00:00:00This is the first time I thought that the aptitude test is done in the first time.
00:00:08Is it secondary or A-level or A-level or frontal board?
00:00:12Nothing can be done in the first time.
00:00:14The international exam is set and it can also come.
00:00:18Now the question is the resistance of wires is cut into four equal parts.
00:00:24And all four parts are bonded together side by side.
00:00:28The better I will write this and later I will write this in the later days.
00:00:36I will write it as a correction, the right and the right.
00:00:40The other parts are added together side by side.
00:00:44I will write it all out of a parallel position.
00:00:47The range is better than identical resistant to the incident or the relative value A-level or A-level.
00:00:55R by 4, if 4 is cut into R by 4, if we divide R by 4, what will happen to R by 16, the final answer is R upon 16.
00:01:08There is an equivalent resistance of an identical resistor connected in parallel is X.
00:01:14If the resistance are connected in series, then equivalent resistor.
00:01:19Parallel and series ratio ratio 1 is 2 N squared.
00:01:24Parallel resistance is S, then N squared is equal to X.
00:01:30Now, we can do this with 5 identical resistance.
00:01:35This is the same thing. N is 5 equal to 5.
00:01:39This is how we can do this.
00:01:42The test is like this.
00:01:45Numerical and numbs are like this.
00:01:49We can do this with X.
00:01:51Initial resistance is 4.
00:01:54Equivalent resistance is 5.
00:01:56Resistance parallel is 5.
00:01:58If it is in series, how much will it be?
00:02:00It will be easy to multiply 25.
00:02:03What is your answer?
00:02:04Your answer is 100.
00:02:06ideal it goes out to the типа machine.
00:02:08Then there are various senzaes.
00:02:12What does it mean to do?
00:02:13What is the 1.
00:02:15Time 5 is 100.
00:02:16The 3 O in the 4 O in the arm.
00:02:19Now, both of this апostitute and f conservatives.
00:02:22worldwide is the 3 iniom resist.
00:02:24세븐 1R.
00:02:27This is the voltage of resistance.
00:02:29How will it be?
00:02:31There are so many formulas.
00:02:33There is a very famous formula, ohms law.
00:02:35V equal to higher.
00:02:41If you look at the voltage, you can remove the voltage.
00:02:45If you multiply 3, it is 2.4.
00:02:47Now listen, the voltage is small.
00:02:49If the voltage is 2.4, then how will it be?
00:02:532.4.
00:02:55How will it be?
00:02:576.4.
00:02:59What is this?
00:03:01Current.
00:03:03Current is 0.8A.
00:03:05What is the current?
00:03:07Add up?
00:03:09No?
00:03:111.2A.
00:03:13Current is 0.8A.
00:03:15Current is 0.8A.
00:03:17Current is 0.8A.
00:03:19Current is 0.8A.
00:03:21How will it be?

00:04:13How do you think?
00:04:1520
00:04:17Here is current and voltage
00:04:21Now let me tell you what current is equal to
00:04:25Voltage upon resistance
00:04:27How do you divide?
00:04:2920
00:04:30Answer 1 upon
00:04:32Here is 3 resistance in series
00:04:36Blast
00:04:38Now let me tell you what instant is equal to
00:04:45Now if you try the parallel
00:04:48Parallel, how many amino acids are there?
00:04:532 also equal to 1
00:04:55If you divide between 2, twice
00:04:583 is divided by 4
00:05:01how this is
00:05:02Now, here is the result of all of this.
00:05:04How today is a series?
00:05:06Series, plus 1.
00:05:07Series is that.
00:05:08Why would you choose the way to do this?
00:05:11This is 5 by 2 plus 3.
00:05:135 by 1, upon 2,
00:05:16final answer has 5 by 2.
00:05:19Let's see,
00:05:21Ecore alert is identical.
00:05:24When it turns out to be the same in the triangle,
00:05:27then call it a identical.
00:05:28there is a
00:05:58And who is in this triangle?
00:06:00Identical resistance.
00:06:02It's equivalent to its equivalent.
00:06:04It's a big deal.
00:06:06You can see it in this triangle.
00:06:08It's identical.
00:06:10And now, we'll take our magical trick.
00:06:12Identical triangle,
00:06:14when it's equivalent to its equivalent,
00:06:16it's called Dubai Games.
00:06:18So, answer 8.
00:06:20Here, see.
00:06:22What is identical?
00:06:24How many?
00:06:26How many?
00:06:282 by 3.
00:06:30How many?
00:06:32How many?
00:06:3420.
00:06:36Now, here's current.
00:06:38And voltage.
00:06:40Now, we'll tell you,
00:06:42what is current?
00:06:44Voltage upon resistance.
00:06:46How many?
00:06:48Answer 1 upon?
00:06:50Here,
00:06:523 resistance in series.
00:06:542.
00:06:562.
00:06:582.
00:07:002.
00:07:022.
00:07:042.
00:07:062.
00:07:082.
00:07:102.
00:07:122.
00:07:143.
00:07:163.
00:07:173.
00:07:183.
00:07:192.
00:07:203.
00:07:212.

00:07:282.
00:07:293.
00:07:302.
00:07:313.
00:07:325.
00:07:335.
00:07:34So, we are going to transform.
00:07:35The final answer is 5 bar apart.
00:07:38Look, we have a little bit of 1 alert.
00:07:40You will have a little bit identical.
00:07:42If we have a little bit of an angle, we will have a little bit identical.
00:07:47If there is a little bit of a signal, then we will have a little bit.
00:07:49The second one is going to be 2 bar apart.
00:07:52If you have a little bit, it will be 20.
00:07:55We have to add 2 bar apart.
00:08:00Since it is a simple, its little bit more.
00:08:02How much is it?
00:08:04If you have any problems, you need to have a problem.
00:08:08You need to have a level of inter.
00:08:10Thanks a lot.
00:08:12I have told you that this is a very complicated circuit.
00:08:16How many 6 resistance are and all 6-6.
00:08:18Let's see how many.
00:08:201, 2, 3.
00:08:223-6, how are parallel?
00:08:24The question in black is blue.
00:08:266-6 is divided by 3.
00:08:282 will come.
00:08:302, 2.
00:08:32Now, let's go side.
00:08:34Here, see, 6 and 6 will be 12.
00:08:36In series, it will be plus.
00:08:386 and 6 will be 12.
00:08:40And the next 6 is parallel.
00:08:42I have to tell you that,
00:08:44in parallel, the number of double is divided by 3.
00:08:46The number of double is divided by 12.
00:08:483 divided by 4.
00:08:50Now, look at the big digits.
00:08:52This is solved.
00:08:54Here, 2 and 4 is enough.
00:08:56How much is the answer?
00:08:58How much is the answer?
00:09:00This is my magical trick.
00:09:02Now, listen.
00:09:04When there are so many things,
00:09:06and the number is always divided by 2,
00:09:08usually, it is the same.
00:09:09It is not necessary.
00:09:10Now, let's go.
00:09:11We are using the same thing.
00:09:13Look, this is the number of double is much more.
00:09:16What is the matter?
00:09:17The number of double is divided by 12.
00:09:19The number of double is divided by 12.
00:09:21The number of double is divided by 12.
00:09:23The number of double is divided by 12.
00:09:25Ab both to the whole.
00:09:30Now, we have to make the number of double...
00:09:31That is the number of double and fits 4.
00:09:32Yes!
00:09:33I didn't see that 48.
00:09:34You read the total much,
00:09:36only 2,
00:09:37Now, remember that we have 11.
00:09:38I'm leaving,
00:09:39and this is the number of
00:09:40O,
00:09:4018
00:09:41to most of the double
00:09:42ESPAC before the season.
00:09:43You can explain that.
00:09:44There are 14.
00:09:44Now,
00:09:45there are 11.
00:09:46How many times
00:09:48You could use counterweight that
00:09:49there is still
00:09:50바� nose?
00:09:51The printer's
00:09:53so long.
00:09:5312 or 24
00:09:55It's a double value
00:09:57It's a big value from 3
00:09:59And the final answer is 8
00:10:01And in 2nd we have solved
00:10:03How much is it?
00:10:05Thanks a lot
00:10:07There is a team resistance in parallel
00:10:09We always solve it
00:10:11We always solve it
00:10:13We will solve it
00:10:15We will solve it
00:10:17When we solve it
00:10:19We will solve it
00:10:21We will solve it
00:10:23We will solve it
00:10:25We will solve it
00:10:27It is a great question
00:10:29We will solve it
00:10:31In 6, 6 and 3
00:10:33We will divide it
00:10:35With 3
00:10:37And 12 and 12
00:10:39We are divided
00:10:418
00:10:43We will divide it
00:10:45This is 8
00:10:47We will divide it
00:10:49So this will be the answer for this circuit.
00:10:53Let me tell you, it's a big one.
00:10:56It's a 9 and a 8.
00:11:02It's parallel.
00:11:04This is a formula.
00:11:06It's not true.
00:11:08I'm going to make it easier than this.
00:11:11Let's see if this is double.
00:11:14It's double.
00:11:16It means 9, 2, and 18.
00:11:19If you don't have any questions,
00:11:21you can divide the big values by 3.
00:11:24If you divide the big values by 3,
00:11:26then the answer will be 6.
00:11:27So 9 and 18 will be the same.
00:11:29Let's look at this formula.
00:11:31We don't have 6.
00:11:32Now, when we're taking 5,
00:11:35we're taking 12 and 24.
00:11:37What's the difference between 12 and 24?
00:11:39Yes, it's 12, 2, and 24.
00:11:41So the big values we divide.
00:11:43What's the answer?
00:11:45This is the same.
00:11:46This is the same.
00:11:47This is the same.
00:11:48This is the same.
00:11:49This is the same.
00:11:50This is the same.
00:11:51This is the same.
00:11:52This is the same.
00:11:53This is the same.
00:11:54This is the same.
00:11:55This is the same.
00:11:56This is the same.
00:11:57This is the same.
00:11:58This is the same.
00:11:59This is the same.
00:12:00This is the same.
00:12:01This is the same.
00:12:02This is the same.
00:12:03This is the same.
00:12:04This is the same.
00:12:05This is the same.
00:12:06This is the same.
00:12:07This is the same.
00:12:08This is the same.
00:12:09This is the same.
00:12:10This is the same.
00:12:11This is the same.
00:12:12How many? Art and 12.
00:12:17Now look, my tricks are big.
00:12:20I'm going to buy my kids.
00:12:22This is not going to happen.
00:12:27Now, if I cut it from 2000,
00:12:31it will be 6 or 10.
00:12:34How much is 8 multiplied by 6?
00:12:3748 upon 10 is 14.
00:12:40If I cut it from 2000,
00:12:42it will be easy for 10.
00:12:45Now, what is the result?
00:12:48This answer is 4.
00:12:50This is 4.8 and 7.8.
00:12:53It will be plus.
00:12:56It will be 12.
00:12:58How much resistance is?
00:13:0012.
00:13:01How much voltage is?
00:13:026.
00:13:03The current is equal to 6 upon 12.
00:13:066 upon 12.
00:13:08So, what is the result?
00:13:10It will be 0.5.
00:13:11What is the result?
00:13:12It will be 0.5.
00:13:14So, what is the result?
00:13:16This is the result.
00:13:18Now, let's go ahead and check out the results.
00:13:20Let's go ahead and check out the results.
00:13:22Now, 6 ohm is connected in series with another resistance of 4 ohm.
00:13:27Across our battery of 20 ohm.
00:13:29Potential difference across 6 ohm resistance.
00:13:32So, what is the result?
00:13:33I mean, look at the result.
00:13:34Resistance is 6 ohm connected in series with a battery of 10 ohm.
00:13:37So, what is the result of the series?
00:13:38What is the result of the series?
00:13:39Resistance is in series.
00:13:41Okay.
00:13:42In series, the result is the result of the sum of resistance.
00:13:47So, what is the result?
00:13:48R1 plus R2.
00:13:506 plus 4.
00:13:52I mean, V equal to IR formula.
00:13:57I equal to V upon R.
00:13:5920 ohm 10 is divided into.
00:14:02Now, my friend, what is the result of resistance in series?
00:14:05What is the result of current?
00:14:06Same.
00:14:07Current is the same.
00:14:08Parallel, the result is same.
00:14:10The result of current is 2 ohm.
00:14:12What is the result of current 2 ohm?
00:14:13Who is the result of this?
00:14:14Since this is the result of resistance?
00:14:156 will multiply the result of 2 ohm.
00:14:17What is the result of 2 ohm?
00:14:18How much is the result of 2 ohm?
00:14:202 ohm.
00:14:21Then, this is the result of 3 ohm.
00:14:243 ohm and 5 ohm are connected in parallel.
00:14:28well we can see what is going on
00:14:33promises
00:14:46this looks like
00:14:47okay
00:14:50rivals

00:16:13i4
00:16:15i4
00:16:174.8.32
00:16:18If you ask me 4 resistance is 8.8
00:16:22So, the maximum value is the maximum value.
00:16:25So, the maximum value is when it is in the series.
00:16:274.8.32
00:16:29But, this is the same 4 resistance.
00:16:33The value is 8.8.
00:16:36You can say that you can use parallel.
00:16:38So, the formula is R upon R.
00:16:418 upon 4.
00:16:43Okay, then.
00:16:45Another big problem.
00:16:478 upon 4.2
00:16:48I have given it.
00:16:49Okay.
00:16:50If you have a minimum combination.
00:16:52So, the minimum combination would be that.
00:16:548 upon 4.2
00:16:56Now, see.
00:16:57If the resistance is used.
00:17:00The current is the same.
00:17:02The voltage is different.
00:17:04When the resistance is parallel, then what happens?
00:17:07Well, see.
00:17:08The voltage is the same.
00:17:10And the current is different.
00:17:12These two original formula.
00:17:14You can do that in the magic trick.
00:17:16So, I will keep you with the Jesuit of this.
00:17:18I will put that in Francis.
00:17:19I will put that in my mind.
00:17:20You need to align yourself.
00:17:21So, the maximum balance of this thing is something.
00:17:22It is a huge mistake.
00:17:23The first is costly of this first 24.
00:17:24This is not a standard.
00:17:25I am doing all the negative.
00:17:26I am doing all the true,
00:17:27Yes, not a standard.
00:17:28Now, I am doing this.
00:17:29But, I am doing it.
00:17:31some good logical formula
00:17:34look at
00:17:36resistance and current
00:17:38voltage
00:17:40then we need to multiply the current
00:17:42voltage
00:17:44power and current
00:17:46voltage
00:17:47then we need to divide the current
00:17:49voltage
00:17:50power and resistance
00:17:52then we need to take the power and resistance
00:17:54product and square root
00:17:56theoretical mcqs
00:17:58can be used by the voltage
00:18:01RIK
00:18:02option BOP
00:18:04option CO
00:18:05square root PR
00:18:07all of them
00:18:08and this is also numerical
00:18:10PR and the voltage
00:18:12this is the three formula
00:18:14we need to take the power
00:18:16now we need to talk about the three formula
00:18:18which comes from resistance
00:18:20this is a great trick
00:18:22resistance, voltage, current, power
00:18:24everything is remembered
00:18:26voltage upon current
00:18:28resistance
00:18:29voltage
00:18:30square upon
00:18:33power
00:18:34resistance
00:18:35power upon current
00:18:37square
00:18:38resistance
00:18:40okay
00:18:41so
00:18:42very important
00:18:44which is important
00:18:45is
00:18:47you can keep
00:18:48keep
00:18:51this
00:18:52resistance
00:18:53okay
00:18:54power
00:18:55voltage
00:18:56square
00:18:57and
00:18:58i square
00:18:59multiply
00:19:00yeah
00:19:01voltage
00:19:02current
00:19:03multiply
00:19:04okay
00:19:05current
00:19:06okay
00:19:07current
00:19:08is
00:19:09current
00:19:10We will divide the power by voltage and the resistance to the current.
00:19:19We will be able to do this trick.
00:19:23We have a number of 03212716654.
00:19:28The port potential difference is needed to charge a battery of 20 volt EMF.
00:19:32An internal resistance of 0.1 ohm at rate of 70.
00:19:37So, what is the source of what potential difference is needed to charge, v equal to e plus r.
00:19:50So, what is the source of what potential difference is needed to charge, v equal to e20.
00:20:06So, what is the source of what potential difference is needed to charge, v equal to e20.
00:20:14Internal resistance, v equal to e20 plus e20 is the answer.
00:20:23So, this is the charge. Charge load, charge load.
00:20:29Battery of 24 volts connected to 10 ohm load and current of 22 ampere flow.
00:20:37Find internal resistance of battery and its terminal voltage.
00:20:42I am going to show you the internal resistance of battery and one of the terminal voltage
00:20:51I am going to show you the battery of 24 volt is connected to 10 ohm load and the current of 22
00:21:00load is related to the internal resistance is 1 hour
00:21:07so what is the terminal voltage? This is a big problem. This is equal to capital Aya
00:21:15well this is the load of capital Aya, 10 ohm
00:21:20current is 2.2
00:21:242.2 when we will apply 10 to 10, this is 22
00:21:29so my brother, this is my mind that we used this formula
00:21:32I am going to show you the value of 22

00:21:50I am going to show you the value of 24
00:21:52minus
00:21:532.2
00:21:54which statement is correct
00:22:08the first option is when EMF of single cell
00:22:11is too small
00:22:15for a particular application
00:22:202 or more can be connected in series
00:22:22see a big point
00:22:23if EMF of single cell
00:22:25is very small
00:22:25then we will have 2 or 2
00:22:27more connected
00:22:29in series
00:22:29this statement is correct
00:22:30after this
00:22:32EMF of this set
00:22:34is sum of EMF of individual cells
00:22:39yes

00:22:44is the sum of individual
00:22:45resistance
00:22:47okay
00:22:47R series
00:22:48equal to R1
00:22:49plus R2
00:22:49plus R3
00:22:50plus R
00:22:51now
00:22:51this statement
00:22:53CA
00:22:53D
00:22:53and E
00:22:54is all of above
00:22:55now look at some
00:22:55some
00:22:56time
00:22:57how is it
00:22:59there is no
00:22:59both A and B
00:23:00option
00:23:01then there is E
00:23:03in all of them
00:23:04A
00:23:04also correct
00:23:05B
00:23:06also correct
00:23:06C
00:23:07D
00:23:07is not
00:23:08correct
00:23:09the answer
00:23:10is not
00:23:11correct
00:23:12but
00:23:13since there is not
00:23:14the answer
00:23:15is not
00:23:16let
00:23:18acid
00:23:19cells

00:23:29to make
00:23:3112V battery
00:23:32of a car
00:23:33this is also a big
00:23:33point
00:23:34now
00:23:35we will study all
00:23:35points
00:23:36well
00:23:37like
00:23:38we are saying
00:23:38lead acid cell
00:23:39in series
00:23:40is an arrangement
00:23:41to make
00:23:42a 12V battery
00:23:43this is the same
00:23:44same way
00:23:44that the lead acid cell
00:23:47is how much
00:23:47battery can be made
00:23:49in the car
00:23:49so
00:23:4912V
00:23:50can be made
00:23:50this is a very important
00:23:51thing
00:23:52after
00:23:53when
00:23:53EMF of cell
00:23:55is sufficient
00:23:55but its capacity
00:23:57is too small
00:24:00or more
00:24:01batteries or cells
00:24:02can be connected
00:24:03in parallel
00:24:05to give one more current
00:24:07the total current
00:24:09is the sum of current
00:24:10deliver
00:24:12for the individual
00:24:13battery or cell
00:24:14so
00:24:15you
00:24:15this is
00:24:16D-state
00:24:16when we
00:24:17correct
00:24:17this is
00:24:17what
00:24:18answer
00:24:18all of
00:24:19what potential difference
00:24:20is needed to charge
00:24:21our battery of 20 volt EMF
00:24:23and internal resistance of 0.1 ohm
00:24:26at rate of 70
00:24:27is the total current
00:24:28the total current
00:24:29the total current
00:24:29is the total current
00:24:30source of what potential
00:24:32difference is needed
00:24:33to charge
00:24:35which is
00:24:36now
00:24:37in the connection
00:24:37which is
00:24:39v equal to
00:24:40e plus
00:24:40k
00:24:41v equal to
00:24:42e plus k
00:24:43Yes, I am saying that it is needed to 20 only, so E 20 only, it's a big deal.
00:24:57I don't know how to keep the start.
00:25:01Current, current, current.
00:25:0470.
00:25:06Internal resistance.
00:25:08I'm going to multiply it.
00:25:1020 plus 7, 27.
00:25:13The answer has come.
00:25:14I'm going to show you this chart.
00:25:16Charge load.
00:25:18Charge load.
00:25:20Battery of 24 volt is connected to 10 ohm load and current of 22 ampere flow.
00:25:28Find internal resistance of battery and its terminal voltage.
00:25:33The battery of 24 volt is connected to 10 ohm load and current of 22 ampere.
00:25:51Load is related.
00:25:53Internal resistance is related.
00:25:58Terminal voltage.
00:26:00This is a big problem.
00:26:02This is equal to capital A.
00:26:05Well, this is a load of capital A.
00:26:1010 ohm.
00:26:11Currently, this is 2.2.
00:26:13This is 2.2.
00:26:152.2.
00:26:16When we multiply from 10 to 10, this is 22.
00:26:20So, my brother, I just have to go to this formula.
00:26:23We use this formula.
00:26:24And this is 22R.
00:26:28EMS is 24.
00:26:30Current to 2.2.
00:26:32R, I need to change.
00:26:33I will change.
00:26:34I will change.
00:26:35I will change.
00:26:3622 and 24.
00:26:38I will change.
00:26:40It will change.
00:26:412.2 R. I call it minus 2, minus 2, minus 2.2. Okay, white. What is the value of 0.9?
00:26:50And this is the answer of question.
00:26:54Now, let's start the current analytics.
00:26:57Now, let's see this chapter.
00:26:59This is the starting system.
00:27:01The other thing is that we don't miss any chapter.
00:27:04We don't miss anything.
00:27:06We don't miss anything.
00:27:08We don't miss anything.
00:27:10V equal to IR.
00:27:12This relationship, ohms log, is very popular.
00:27:15We don't miss the matrix.
00:27:17Voltage equal to current multiplier resistance.
00:27:20But, one thing is voltage and one thing is electro-voltage force.
00:27:26The other thing is different.
00:27:28The other thing is equal to voltage.
00:27:30Electro-voltage force is greater than voltage.
00:27:32Electro-voltage force is greater than voltage.
00:27:34So, this is the big ohms.
00:27:37Now, let's go.
00:27:39This is a mobile.
00:27:41This is a mobile.
00:27:42I will disconnect its battery.
00:27:44What do I do?
00:27:46Disconnect it.
00:27:47So, V equal to E.
00:27:49The voltage is equal to electro-voltage force.
00:27:52Listen to this.
00:27:53It's very small.
00:27:54It's very small.
00:27:55It's very small.
00:27:56It's very small.
00:27:57Look at the other.
00:27:58But, if you want to change the voltage.
00:28:00Now, if you want to change the voltage,
00:28:01we can use the voltage force.
00:28:02How can you use the voltage?
00:28:03This is the voltage force.
00:28:04How can you use the voltage force?
00:28:05V equal to E minus IR.
00:28:07I iso current, R iso current.
00:28:09Internal resistance.
00:28:10resistance
00:28:12and in this way the electromotive force is increased
00:28:15and we can see that
00:28:17v is equal to e minus i
00:28:19so this is the load condition
00:28:21and charge of the load
00:28:23and numerical also we can see that
00:28:25load values or charge
00:28:29and if I charge this mobile
00:28:31then what will happen
00:28:33v is equal to e plus
00:28:35and so on
00:28:37v grunted
00:28:39so that the three things
00:28:41can be done in the mind
00:28:43and keep the three conditions
00:28:45in the mind
00:28:47and if there is one condition
00:28:49we can follow
00:28:51any condition
00:28:53we can follow
00:28:55there are many questions
00:28:57because charging
00:28:59we can do
00:29:01but we are not doing anything
00:29:03so we will be doing
00:29:05we will start
00:29:07current and electricity
00:29:09and we will see
00:29:11the starting system
00:29:13and we will see that
00:29:15any other chapter
00:29:17we have no tension
00:29:19and we will do it
00:29:21we will do it
00:29:23we will do it
00:29:24and you will see that
00:29:25we will see us
00:29:26this is what we have to do is we have voltage equal to current multi-planned resistance
00:29:31but one thing is voltage and one thing is electromotiforce
00:29:37the difference between these two is equal or the voltage is
00:29:41electromotiforce is bigger than the voltage is bigger than the voltage is bigger than the voltage
00:29:45so this is a big concept
00:29:50now this is mobile
00:29:53I will disconnect the battery of the battery.
00:29:56What do I do?
00:29:58Disconnected.
00:29:59V is equal to E.
00:30:01V is equal to E.
00:30:03Electromotive is equal to E.
00:30:04If you listen to the attention,
00:30:05it is very difficult.
00:30:06It is very difficult.
00:30:07It is very difficult.
00:30:08It is very difficult.
00:30:09It is very difficult.
00:30:10It is very difficult.
00:30:12How can we use it?
00:30:14Load.
00:30:15V is equal to E minus I.
00:30:19R is equal to internal resistance.
00:30:22In this way,
00:30:25Electromotive force is increased.
00:30:27And we can see that
00:30:29V is equal to E minus I.
00:30:31So, load is equal to charge.
00:30:33Numerical is equal to load.
00:30:36Load is equal to charge.
00:30:39If I charge a mobile,
00:30:42what will happen?
00:30:44V is equal to E plus I.
00:30:47So, V is equal to E.
00:30:50So, three things can be used.
00:30:53Three conditions can be used.
00:30:55In the mind of it.
00:30:56If there is one condition,
00:30:57it can be used.
00:30:59It doesn't matter.
00:31:01It doesn't matter.
00:31:02We can follow any condition.
00:31:04We can not do any condition.
00:31:05In the paper,
00:31:06there are many questions.
00:31:08It is related questions.
00:31:09Charging conditions will be used.
00:31:11In the paper,
00:31:12the generator of EMF 80V has an internal resistance of 0.04 ohm.
00:31:26If its terminal voltage is 75 ohm,
00:31:29find current.
00:31:31EMF 80 is,
00:31:33terminal voltage 75 is,
00:31:35current is,
00:31:36internal resistance of 0.00 ohm.
00:31:38This 75 ohm,
00:31:4080 ohm,
00:31:41minus 5.
00:31:42And,
00:31:43when we divide the 5,
00:31:440.04 ohm,
00:31:45then,
00:31:46final answer is,
00:31:47125 ohm.
00:31:48This is a good question.
00:31:49Cell negligible resistance.
00:31:51NEMF 20V.
00:31:53It is connected across series combination.
00:31:562,
00:31:573 and 5 ohm.
00:31:58Potential difference across 3 ohm resistance.
00:32:01We get to 16.
00:32:02V is a basic one.
00:32:03What does the resistance group need to do?
00:32:0410th.
00:32:05V is equal to IR of small formula.
00:32:06V is 20.
00:32:07Our base of ADHD has Uh,
00:32:0810 to P
00:32:28I feel like an other thing you have to say that you have to say that you have to say
00:32:35that you have to say that you have to say that you have to say that I will
00:32:41follow a resistance of why this is our it is third into four equal part and all
00:32:48four part are bonded together side by side resistance of bundle to the goal
00:32:55all the parts are rounded together side-by-side side-by-side
00:33:08parallel parallel to the identical resistance to the incident already value hey are my phone
00:33:19the charge so many are my phone this company's phone so divided by the other thing on the line
00:33:26R upon 16. Final answer is R upon 16.
00:33:31So, there are equivalent resistance of an identical resistor connected in parallel is X.
00:33:37If the resistance are connected in least than equivalent resistance.
00:33:40So, there are equivalent resistance.
00:33:42Parallel and series ratio ratio 1 is 2 N square.
00:33:47Now, parallel resistance S is N square X.
00:33:51Now, we can do this as well as 5 identical resistances.
00:33:57So, we can do this as well as N-Bram 5.
00:34:00So, we can do this as well as 5 test per item.
00:34:01So, we can do this as well as all.
00:34:04Let's see.
00:34:05It was like this in Numerical and Nums test.
00:34:11And we can do this as well as the value of X.
00:34:14Initial resistance is 4, equivalent resistance.
00:34:18Now, 5 resistance is parallel.
00:34:21When it's in series, how much will it be?
00:34:23It's very easy to multiply 25.
00:34:26What do you think?
00:34:274.
00:34:28What is your answer?
00:34:29That's a very difficult question.
00:34:32Look, you have to test tricks on the other side.
00:34:34What is the value of X?
00:34:36The value of X is black.
00:34:373 ohm, 6 ohm resistance.
00:34:39Parallel then, 4 ohm resistance.
00:34:41The value of X is 3 ohm resistance.
00:34:43The current value of X is 0.0.
00:34:46How much is 0.0.
00:34:47And 4 ohm resistance.
00:34:51How much will it be?
00:34:53How many formulas are?
00:34:55There is a very popular formula for ohms.
00:34:58V equal to higher.
00:35:00What has the value of X is 0.0.
00:35:04It will be 0.0.
00:35:07Now, if you see this, the value of X is 0.5.
00:35:12By the value of X is 0.0.
00:35:15The value of Y is 0.5.
00:35:19This is 60.4.
00:35:21What is the current?
00:35:23Current.
00:35:25The current is 0.8A.
00:35:27The current is 0.4A.
00:35:29What happens in parallel?
00:35:31Add up?
00:35:331.2A.
00:35:35The current is 1.2A.
00:35:37Current is 0.8A.
00:35:39Current is 0.8A.
00:35:41Current is 0.8A.
00:35:43How much?
00:35:451.2A.
00:35:47How much?
00:35:494.8A.
00:35:514.8A.
00:35:53This is your answer.
00:35:55Awesome.
00:35:57No doubt.
00:35:59This resistance is 4.4A.
00:36:01Is it not?
00:36:03And in the triangle?
00:36:05Identical resistance.
00:36:07It's an equivalent.
00:36:09It's a big deal.
00:36:11It's a triangle.
00:36:13It's identical.
00:36:15And now let's take our magical track.
00:36:17Identical triangle.
00:36:19It's a big deal.
00:36:21It's a big deal.
00:36:232x8A.
00:36:25Answer 8.1A.
00:36:27Look at this.
00:36:29What are identical?
00:36:31How many?
00:36:33It's a big deal.
00:36:352x8A.
00:36:37What should I do?
00:36:39What are the current?
00:36:41So, here.
00:36:43Current is 0.7A.
00:36:45And voltage is 0.8A.
00:36:47What is the current?
00:36:49What is the current?
00:36:51What is the current?
00:36:532x8A.
00:36:542x8A.
00:36:551x8A.
00:36:562x8A.
00:36:572x8A.
00:36:592x8A.
00:37:012x8A.
00:37:022x8A.
00:37:042x8A.
00:37:052x8A.
00:37:061x9A.
00:37:082x8A.
00:37:10Parallel and Domain.
00:37:12Parallel.
00:37:14Parallel.
00:37:16Somed mastered as many variables.
00:37:18You already have more than 1x4A.
00:37:19Only when double replaced it,
00:37:222x4A.
00:37:242x7A.
00:37:26We all have to solve it. Now we have to solve it.
00:37:29This is a series.
00:37:30It's a series.
00:37:31It's a series.
00:37:32We have to solve it.
00:37:33This is a problem.
00:37:34So, we have to solve it.
00:37:352R plus 3R.
00:37:375R upon the problem.
00:37:40Final answer is 5R upon the problem.
00:37:43Look at that.
00:37:45Equivalent is identical.
00:37:48When we have to solve it, we can solve it.
00:37:50We can solve it.
00:37:51Equivalent is identical.
00:37:52We can solve it.
00:37:53Let's make it happen.
00:37:54Let's ask if we have a problem with the current problem.
00:37:58If we have 2R upon 20, we have to solve it.
00:38:00They have to solve it.
00:38:01I have to solve it.
00:38:033Rs and 3Rs.
00:38:053Rs and 3Rs.
00:38:071Rs is not enough.
00:38:084Rs is not enough.
00:38:10This is not enough.
00:38:11First, we have to solve it quite a bit.
00:38:14We have to solve the problem.
00:38:15Let's solve it.
00:38:17Then, we have to share.
00:38:18I told you.
00:38:19It's a very complicated circuit.
00:38:21How many resistors are all 6-6?
00:38:251, 2, 3.
00:38:273-6. How are parallel?
00:38:29Blacks question is, blue is 6-9, 6-3 divided.
00:38:332 will be 2.
00:38:352 will be 2.
00:38:372 will be 2.
00:38:39Here, 6 and 6 will be 12.
00:38:41In series, it will be plus.
00:38:436 and 6 will be 12.
00:38:45And below 6 is parallel.
00:38:47I don't know how many tricks.
00:38:49In this parallel, when the difference is double,
00:38:51it will be 3 divided by 3.
00:38:53The value is 12.
00:38:553 divided by 4.
00:38:57Now look at this.
00:38:59This is solved.
00:39:012 and 4 will be 2.
00:39:032 and 4 will be 6.
00:39:05How big is it?
00:39:07These are my magical tricks.
00:39:09Listen.
00:39:11When there are so many things,
00:39:13and this number is repeated,
00:39:15usually it is the same.
00:39:17Let's see.
00:39:19Let's see.
00:39:21Look at this number.
00:39:23There are so many things.
00:39:2516 and 16 will be divided by 2.
00:39:278 will be divided by 8.
00:39:298 and 8 will be divided by 2.
00:39:31This will be divided by 4.
00:39:33This will come from here.
00:39:35Now in the series,
00:39:374 and 24 plus 24.
00:39:39Let's see.
00:39:419 and 18 will be divided by 3.
00:39:439 and 18 will be divided by 3.
00:39:459 and 18 will be divided by 3.
00:39:47So the value is divided by 3.
00:39:4918 will be divided by 3.
00:39:516 plus 6 is 12.
00:39:53Look at this.
00:39:55Now there is a chance that
00:39:57you will be divided by 3.
00:39:59How will you do it?
00:40:01Look at this.
00:40:0212 and 26.
00:40:03Double value is divided by 3.
00:40:05And the final answer is 8.
00:40:07And in the second time,
00:40:09we have solved it.
00:40:10So it's like this.
00:40:11Thanks a lot.
00:40:12So there are 3 resistance in parallel.
00:40:14We always solve it.
00:40:16We are trying to solve it.
00:40:17The value is the same.
00:40:18The value is the same.
00:40:19We will solve it.
00:40:20The value is the same.
00:40:21The value is the same.
00:40:22The value is the same.
00:40:23We will solve it.
00:40:24The value is the same.
00:40:26The value is the same.
00:40:27And the value is the same.
00:40:28Once we are identically.
00:40:29I have told that.
00:40:30The value is the same,
00:40:31how much it does are divided by 2.
00:40:32The value is the same.
00:40:33Now,
00:40:34here we will show you how to do it.
00:40:36Let's continue using the value.
00:40:37The value of 6 to 3.
00:40:39and 3.
00:40:40I will divide the value of 6.
00:40:41And 3.
00:40:43Once we divide the value of 12.
00:40:44we divide the value of 16.
00:40:46And they divide the value of 16.
00:40:478 again.
00:40:48Then again,
00:40:49These 2.
00:40:50The value of 8.
00:40:51Now this.
00:40:52If you divide between two and two, then it will be the answer to this whole circuit.
00:40:59Do you know what I'm talking about?
00:41:02It's a big answer.
00:41:051,9 and 1,8.
00:41:09It's parallel.
00:41:11This is a formula.
00:41:12It's not true.
00:41:14I'm going to make it easier than this.
00:41:17You can't do anything.
00:41:19What is the difference between two and two?
00:41:22Double means 9,2,18.
00:41:25If you divide the difference between two and three,
00:41:3018 and three, it's a answer.
00:41:33If you do not work with this formula,
00:41:37we will divide the difference between two and twenty-four.
00:41:43What difference between two and twenty-four?
00:41:45Yes, it's twelve and twenty-four.
00:41:47So, I'm going to divide the difference between two and twenty-four.
00:41:49What is the answer?
00:41:50What is the answer?
00:41:51Yes.
00:41:52What is the answer?
00:41:53What is the answer?
00:41:54What is the answer?
00:41:55All right.
00:41:56All right.
00:41:57All right.
00:41:58All right.
00:41:59What?
00:42:00It's parallel.
00:42:01The car resist.
00:42:02The car resistance is a 7.2.
00:42:03It is in the series.
00:42:04And the voltage is in the current.
00:42:05The voltage and the current.
00:42:07You see, it's so long.
00:42:08But it's pretty short.
00:42:09All right.
00:42:10The third rule.
00:42:11The two parallel.
00:42:12The parallel.
00:42:13The shortcut formula for the first.
00:42:15The two products are in the lower.
00:42:18The two products are in the lower.
00:42:19The other two products are in the lower.
00:42:21The one art.
00:42:22And the other one.
00:42:23Now, look, my tricks are big. I look at the kids of the bio.
00:42:29Is this okay?
00:42:31Is this okay?
00:42:33Now, if I cut it from 2000,
00:42:37it will be 6 or 10.
00:42:40How much is 8 multiplied by 6?
00:42:4348.
00:42:44Upon 10, 4.8.
00:42:46I don't want to cut it.
00:42:47I don't want to cut it.
00:42:48I don't want to cut it.
00:42:49When it comes to 10, it becomes easy.
00:42:51Now, look.
00:42:53What's the benefit?
00:42:54This whole answer is 4.8.
00:42:56This is 4.8 and 7.8.
00:42:58This is 3.8.
00:43:003 will be plus.
00:43:02This is 12.
00:43:04How much resistance is 12?
00:43:06How much voltage is 12?
00:43:08How much voltage is 6?
00:43:09Current is 6 divided by 12.
00:43:126 divided by 12.
00:43:146 divided by 12 is 0.5.
00:43:16What's the unit?
00:43:18I don't know.
00:43:20It is 0.5 Ampere.
00:43:22In this way, the answer is very fast.
00:43:24This is the answer.
00:43:25There is a more magical trick.
00:43:27Very fast.
00:43:28As you can see,
00:43:30there is no one.
00:43:31There are resistance.
00:43:33Here, we have a magical trick.
00:43:34Here, we have a formula.
00:43:35There is a formula.
00:43:36I1 is equal to I2.
00:43:37I3 is equal to I.
00:43:38I2 is equal to I.
00:43:39I2 is equal to I.
00:43:40I2 is equal to V1 plus V2.
00:43:41I2 is equal to V3.
00:43:42R R R R 1 plus R 2 plus R 3 Maximum result R multiply by minimum result R divided by Parallel
00:43:53R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R R
00:44:234 resistance
00:44:25How many?
00:44:27All 8 are
00:44:29If it's in series
00:44:31What result?
00:44:33If it's identical to n parts
00:44:358 4s are 32
00:44:39If you have asked
00:44:414 resistance
00:44:43Then the maximum value
00:44:45maximum value is when it's in series
00:44:474 8s are 32
00:44:49But this is the same
00:44:514 resistance
00:44:53The value of their
00:44:55R-R-T
00:44:57You have to say that they have parallel
00:44:59So the formula is R upon
00:45:018 upon 4
00:45:032
00:45:05One more big part
00:45:078 upon 4, 2
00:45:09I have said
00:45:11If they have minimum combination
00:45:13Minimum combination
00:45:158 upon 4, 2
00:45:17If it's in series
00:45:19The current is the same
00:45:21The current is the same
00:45:23The current is the same
00:45:25When the resistance is parallel
00:45:27Then what happens?
00:45:29The current is the same
00:45:31The current is the same
00:45:33The original formula
00:45:35I will do the magical trick
00:45:37That is why you have to worry about
00:45:39You have to pay more
00:45:41It's very dangerous
00:45:4320-20 seconds
00:45:45It's very dangerous
00:45:47That is why I am
00:45:49I will do the best
00:45:51This is the same
00:45:53I think

00:46:133
00:46:14to mq bar minus 2.
00:46:16Now,
00:46:17this is the concept of height.
00:46:20Dog had a test
00:46:21in this time.
00:46:22Resistant directly proportional
00:46:23to length
00:46:24and inversely proportional
00:46:25to the area.
00:46:27The way the length
00:46:29is more than the resistance
00:46:30is more than the area.
00:46:31The area will increase.
00:46:32The amount of time
00:46:32will increase.
00:46:33I will make this role
00:46:34that proportionally
00:46:34is equal to or constant.
00:46:37This is raw.
00:46:37Resistivity.
00:46:39Now,
00:46:40resistivity
00:46:40which is the same?
00:46:41Resistant
00:46:42multiply by area
00:46:43divided by length.
00:46:46And the area
00:46:46is the same length
00:46:47in this way.
00:46:47So,
00:46:48you know,
00:46:48you have to have
00:46:49resistance
00:46:50and length
00:46:50So,
00:46:51you have to multiply
00:46:52the resistance
00:46:53and then you have to
00:46:53resistivity.
00:46:55Dimension
00:46:55and we will use this.
00:46:59Now,
00:46:59the situation
00:47:00is the same.
00:47:02They have to
00:47:03remove resistivity
00:47:04from the area.
00:47:05Resistant
00:47:06in the area
00:47:07the value of resistance
00:47:08is the same.
00:47:08How much is the same?

00:51:00अब फिर सम्झाए उसमेना कॉबे इपर लेख लो सीदी साधे बात है
00:51:06increase the probability of collision of free electrons with which एक ये भीजी थी मैंने
00:51:14ultimately affect the drift velocity of free electrons for a given voltage और अब बता रहें
00:51:20with rising temperature the decrease in drift velocity is attribute to decrease in the electrical
00:51:26current और the increase in electrical resistance for given applied voltage बिल्कुल साइची और
00:51:33d state मेंने electrical current depend upon drift velocity of free electrons
00:51:41तो चीज का answer of course क्या हो गया all of these
00:51:43महाँ अच्छा साले if resistance of wire at 0 degree centigrade is r0 and at higher temperature is t degree centigrade
00:51:52it is rt नहीं 0 degree centigrade पे उसकी resistance r0 है और t degree centigrade पे उसकी resistance rt है
00:52:01तो change in resistance is rt minus r0 equal to del r चलो गई यह बाद भी साइच में आ गई
00:52:07आगे क्या कहने
00:52:08for a change in temperature t0 minus 0 degree is equal to del t चलो चलो चलो चलो चलो चलो चलो चलो चलो
00:52:13then the constant alpha known as temperature coefficient of resistance
00:52:20or of resistivity is equal to option a है rt minus r0 r0 del t और यह क्रेक्क आंसर है बच्छो फिर option वी में दिया था
00:52:29We have given RT plus R0, R0 minus DLT, so we can give Rt and R0 value to the resistance.
00:52:38DLT value to alpha.
00:52:41Usually, it's not like this in the statical numerical, that alpha value is given.
00:52:46So, it's not like DLT.
00:52:49So, this was the option of COD.
00:52:52The correct option is which?
00:52:54A.
00:52:56The option is the length of the conductor, the longer the conductor, the greater the would be, should be resistant.
00:53:08The longer conductor, the longer conductor, the longer conductor, the longer conductor.
00:53:16The cross-sectional area of a conductor, thicker, wire has less resistance.
00:53:23An-ging, if an area gets more than URX, then it costs less resistance.
00:53:28So my brother, the option D, used to all of them are given.
00:53:35Just like for
00:53:43As the material of which the conductor is made, under the same conditions, wires of different metals show different value of resistance.
00:53:57Of course, this one is also true.
00:53:59This answer is all of them.
00:54:01Three resistors of 1 ohm, 2 ohm and 3 ohm are connected in series through a battery of 12 volt.
00:54:09The current flowing through each resistor will be.
00:54:13So, 1 ohm, 2 ohm, 3 ohm connected in series?
00:54:17And how much battery is?
00:54:1912 volt.
00:54:20In series, it will be more than 1, 2, 3, and 6.
00:54:25Well, I know that there is a formula that refers to IR.
00:54:29If IR is 12 and IR is 6, then IR is very fast.
00:54:34How is IR?
00:54:36If IR is 6, then IR will be 2 ohm.
00:54:40And this is your answer.
00:54:42Another great question.
00:54:43Combining 3 resistors of 5.5 ohm, the maximum equivalent resistor.
00:54:49Maximum is when it comes to series.
00:54:52If it comes to 3, we will multiply 3.
00:54:55If it comes to minimum, we will keep parallel.
00:54:58If it comes to 3, we will divide 3.
00:55:01Let's see.
00:55:02Now, this is a good question.
00:55:03It's a good question.
00:55:04Cell-negligible resistance.
00:55:05NEMF, 20 volt.
00:55:07It's connected across series combination.
00:55:102, 3, and 5 ohm.
00:55:12The potential difference across 3 ohm resistance.
00:55:15How much is resistance?
00:55:1710
00:55:19V equal to IR
00:55:21V20
00:55:23R10A20
00:55:25Current is 2 Ampere
00:55:272 Ohm Resistance
00:55:292 Ohm
00:55:312 Ohm
00:55:332 Ohm
00:55:354
00:55:37What?
00:55:39Siemens
00:55:41Semen's Conductive
00:55:45MHO
00:55:49MHO
00:55:51MHO
00:55:53Cement
00:55:55Conductivity
00:55:571 upon RO
00:55:59L upon AR
00:56:01C
00:56:03Conductivity
00:56:05Resistivity
00:56:07Resistivity
00:56:09What is the formula?
00:56:11AR upon N.
00:56:13AR was above and L was below.
00:56:15So, when this is reciprocal,
00:56:17the conductivity of this,
00:56:19what will happen?
00:56:21L is above and AR is below.
00:56:23So, the conductivity is equal to this,
00:56:25and this is also equal to this.
00:56:27This is the same.
00:56:29This is the same.
00:56:31The power is 12.8 watts
00:56:33when current is 4 ampere.
00:56:35If the resistor is the same,
00:56:37the power is the same.
00:56:39So, tell us,
00:56:41how much power is in 6 ampere?
00:56:43Wow!
00:56:45Wow!
00:56:47Power is equal to I2 into R.
00:56:51So, R is equal to P upon I2.
00:56:55Now, the game is,
00:56:57which is the resistance?
00:56:59If it is R1,
00:57:01then it is P1, I1.
00:57:03If it is R2,
00:57:05you call it P2 upon I2.
00:57:07But, when we say that
00:57:09the power of both resistance is equal,
00:57:11what would it be?
00:57:13Yes,
00:57:14this could be a matter of situation.
00:57:16This could be a bit of an issue.
00:57:18So,
00:57:19when we have to use a system,
00:57:21we have to use the base.
00:57:22Power is 1 through 12.8.
00:57:24Hmmmm...
00:57:26i1 square is 4 square is 4 square is 4 square is 4 square is 4 square?
00:57:32i2 square is 6 square and i1 square is 4 square
00:57:38Power 2 is 4 square
00:57:41Now calculate the number of 2 square square is a square of square square
00:57:44multiply and we turn the count on the end of the square right??
00:57:52This is the question that we can convert from electrical energy to this device.
00:58:00This is the device which is called thermo.
00:58:04This is very important.
00:58:06The question is that voltage is 100 volt, current is 10 ampere, resistance is 5 ohms,
00:58:13and internal resistance is 5 ohms.
00:58:15This is the direct formula.
00:58:18V upon I minus I, this is internal resistance.
00:58:23Well, voltage is how much?
00:58:25100.
00:58:26Let's write.
00:58:27I is how much?
00:58:29It is 10.
00:58:30And this resistance is 5.
00:58:32100 upon 10 is how much?
00:58:3410.
00:58:3510 minus 5 is 5.
00:58:36The answer is 5.
00:58:382.
00:58:393 resistance is 7, 5 and 8 ohms.
00:58:44So, what is current?
00:58:477 ohms, 5 ohms, so well resistant is series.
00:58:52And when it is in the resistance series, what is current?
00:58:56What are the same?
00:58:57Yes, if it is in the resistance parallel, then voltage is voltage.
00:59:02Yes.
00:59:03Now, the question is, the 3 resistance are R1, R2, R3.
00:59:07Again, the R1 is R2.
00:59:09R1 is R2.
00:59:10It is R2.
00:59:11It is R2.
00:59:12It is R3.
00:59:13It is R2.
00:59:14It is R2.
00:59:16So, the equivalent resistance is less than R1, equal to R1, less than R3, greater than R1.
00:59:20R1. So, keep those three sum.
00:59:23When the series has resistance, it will be equivalent to three sum.
00:59:26I hope it will be greater than R1.
00:59:28So, the correct option is greater than R1.
00:59:32The correct option is greater than R1.
00:59:35So, the correct option is greater than R1.
00:59:39Today, we are doing current and electric city,
00:59:42past fiber, MCQs.
00:59:44How are they?
00:59:46So, EMF.
00:59:49Basically, electo-morti force.
00:59:52What do I say?
00:59:53So, what is the unit?
00:59:55What is the unit?
00:59:56Potential difference.
00:59:58What is the unit?
01:00:00What is the unit?
01:00:02What is the unit?
01:00:04What is the unit?
01:00:06What is the unit?
01:00:08What is the unit?
01:00:10What is the unit?
01:00:12What is the unit?
01:00:14Current and voltage.
01:00:16The unit of charge.
01:00:17Then, if the unit is equal to and constant,
01:00:18which is equal to?
01:00:19Which is the unit?
01:00:20Which unit's constant then?
01:00:21So, if you have a mistake, you will not be wrong.
01:00:23Constant of Proportionality
01:00:25This is what we see from MCQ.
01:00:27What is constant of proportionality in the Ohm's Law?
01:00:31What is constant of proportionality?
01:00:33What is constant of proportionality?
01:00:35What is constant of proportionality?
01:00:37One upon are very important.
01:00:39Now, my brother, one small part.
01:00:41If the wire is in the current,
01:00:43then the magnetic field has 4 sides.
01:00:45Now, I am wondering what you are asking.
01:00:49If the magnetic field is anti-clockwise,
01:00:55then the direction of current will be.
01:00:57Then the direction of current will be.
01:00:59And if the wire is clockwise,
01:01:01then the direction of current will be.
01:01:03Downward will be.
01:01:05Now, this is the resistivity.
01:01:09Resistant into area of alignment.
01:01:11Iron resistivity is very important.
01:01:13If I have been asked,
01:01:151 to 10 to 10,
01:01:17minus 8 ohm meter.
01:01:19Remember that the resistance unit is ohm.
01:01:21And the raw,
01:01:23the resistivity unit is ohm meter.
01:01:25Let's go, this is ohm meter.
01:01:27What is the ohm meter?
01:01:29What is the ohm?
01:01:31What is the ohm unit?
01:01:33Let's go.
01:01:34If this is the conductance unit,
01:01:35then what is the conductance?
01:01:37Conductance is the resistance of the reciprocal.
01:01:39The one upon r.
01:01:41Okay.
01:01:43If one upon r is the conductance,
01:01:45the resistance of the reciprocal,
01:01:47then it is the resistivity.
01:01:49It is the reciprocal of the reciprocal.
01:01:51It is absolutely true.
01:01:53One upon raw is the reciprocal of the conductivity.
01:01:55The resistivity of the reciprocal is the conductivity.
01:01:57The resistance of the reciprocal is the conductivity.
01:01:59And the resistance of the reciprocal is the conductivity.
01:02:03And that is the question which I have all said.
01:02:05In which of following more heat energies produced.
01:02:11So,
01:02:13Bulb of resistant 50 ohm.
01:02:155 ohm.
01:02:17Operated for
01:02:191 minute.
01:02:21By applying current of 120 ampere.
01:02:25Well,
01:02:27Let's see.
01:02:29An iron producing heat energy of 2 kilojoules.
01:02:332 kilojoules?
01:02:35A tube working for 2 minute with supply of 50 ampere current.
01:02:39And offering a resistance of 0.02 ohm.
01:02:43Both ANC produced same energy.
01:02:47So,
01:02:48this is a formula.
01:02:49Power equal to I square into power.
01:02:52I call current.
01:02:53Current of the square is the resistance.
01:02:55Now,
01:02:56heat and energy
01:02:57How do we get the power of time?
01:02:59When we get the power of time?
01:03:01Well,
01:03:02Well,
01:03:03Well,
01:03:04Heat and energy
01:03:06You can be the power of power as R as well.
01:03:07You can be the power of power as R as well.
01:03:08You can be the power of power as R as well.
01:03:09Now,
01:03:10This is energy.
01:03:11Aqua is the power of power as R as well.
01:03:12I square R T.
01:03:13Now,
01:03:15Up from the first case,
01:03:18I 1,
01:03:19This is the power of power is the power of power.
01:03:20It's more than two or four.
01:03:21In the first case,
01:03:22I 120.
01:03:23The power of power is really big.
01:03:24And what is this power?
01:03:25How does that?
01:03:26It's square.
01:03:27Then, R is 5 ohm. Time is 1 minute and 60 seconds.
01:03:34You can see that the value is very big.
01:03:38In the third case, we see that it is 2 minutes and 0.02 ohm is 50 amp.
01:03:44Well, of course, 50 is smaller than 120.
01:03:48So, 50 square is also smaller.
01:03:52Then, 0.02 and 62.
01:03:54You can see which value is bigger.
01:03:56You don't have to calculate it.
01:03:58In the third case, the value is bigger.
01:04:01The option is A.
01:04:03Of course, the result is 2000.
01:04:06Because 12 square is 144.
01:04:09And 0 is also 144.
01:04:12Of course, the answer is the option.
01:04:14Okay, let's see.
01:04:16Power, voltage, current and resistance.
01:04:19There are 4 big things.
01:04:21And...
01:04:28Let's go see...

01:09:15This is a very important thing.
01:09:19This is all resistance.
01:09:23Okay, if power needs voltage,
01:09:27then R-C divide.
01:09:29or resistance to I-square.
01:09:31or voltage to current to current.
01:09:35Okay, if current needs power and resistance voltage,
01:09:41then power to resistance divide.
01:09:43If current needs power,
01:09:45then power to voltage to divide.
01:09:47and voltage to resistance to current.

01:09:59So, current's definition.
01:10:03Basically, one is called an electronic current
01:10:05or a rail current.
01:10:07And one is called a convention.
01:10:09How is MCC?
01:10:11An electric current through a conductor
01:10:13is due to drifting of the electron.
01:10:15The electron always drift from lower potential,
01:10:17negative terminal of battery
01:10:19to a higher potential,
01:10:21opposite to electric field.
01:10:23This current is called electronic current.
01:10:25or electronic current.
01:10:27In the lower potential,
01:10:29the higher potential,
01:10:31the electron is called,
01:10:33what is the current?
01:10:35Rail current or electronic current?
01:10:37If you give it to lower,
01:10:39the higher potential,
01:10:41the current is called.
01:10:43Option A, electronic current.
01:10:45Option B, rail current.
01:10:47So, all of them.
01:10:49Conventional current,
01:10:51which is due to flow of equivalent
01:10:53positive charge from higher,
01:10:55here positive terminal.
01:10:59Positive terminal to a lower,
01:11:01negative terminal is called conventional current.
01:11:05Conventional current.
01:11:07In conventional current,
01:11:09So, there are a lot of important things.
01:11:11You can see a lot of things.
01:11:13Thanks a lot.
01:11:15So, there are a lot of important things.
01:11:17You can see a lot of things.
01:11:19Thanks a lot.
01:11:21Also, current effects is contain.
01:11:23Now, current effects.
01:11:25So, these current effects are also heating effects.
01:11:27Like, the heaters are current,
01:11:28the heating effects.
01:11:29Electric iron is current.
01:11:31Electric iron is current heating effect.
01:11:33Electric lamp is유 turn.
01:11:35Electric lamp unfolds and fuses.
01:11:37Make sure each heater is good here.
01:11:39Electric iron stands in the middle.
01:11:41Electric lamp is all heating effects.
01:11:43The power effects are the chemical effects.
01:11:45So, this is a lot of the chemical effects.
01:11:47The power of electricity and electricity.
01:11:48Although it also is very much.
01:11:49So, this is very important.
01:11:50and magnetic effect, meters, fans, relays, electric belts, motors, transformers, these are all magnetic effects.
01:12:04So, this is a very important topic.
01:12:07When current is set up in a wire by connecting,
01:12:13by connecting its end respectively to the two terminals of the battery,
01:12:22the electron moves along the circuit from negative terminal to the positive terminal of battery.
01:12:32This is called as dash current.
01:12:36So, this is a very important topic.
01:12:43When current is set up in a wire,
01:12:47by connecting its end respectively to the terminal of the battery,
01:12:51the electron moves along the circuit from negative terminal to positive terminal of battery.
01:12:56This is called S.
01:12:57So, what does this mean?
01:12:59Electronic current.
01:13:00Which is the proper definition?
01:13:02Electronic current.
01:13:03Negative to positive terminal current.
01:13:06Drivelosity का topic.

01:15:32After you test hard work is more smart, how genius you are.
01:15:42This is a very good question. Thermo couple is connected across galvanometer of 30 ohm.
01:15:50One junction is immersed in water at 373 Kelvin and other in eyes at 273 Kelvin.
01:16:00EMF of thermo couple is 90 microvolts for each 1 Kelvin difference in temperature.
01:16:12Between injections and thermo couple resistance is 6 ohm.
01:16:18What current will show in galvanometer?
01:16:21DoHS, NUSTO, NUMZO, these are the same questions.
01:16:25You can take A level physics from each other.
01:16:28The first thing is temperature difference.
01:16:32The difference between 373 and 273 is 100 Kelvin.
01:16:36And in thermo couple, how do you get EMF?
01:16:40The voltage of thermo couple is multiplied by temperature difference.
01:16:47Actually, EMF is not the same.
01:16:49The difference between thermo couple is 90 microvolts and 9000 microvolts.
01:16:55Państwo is without this respect.
01:16:56The resistance from Canon's current limit.
01:16:57Total resistance, how do you do this?
01:16:58Look at the resistance?
01:16:59Deep resistance being 30, 1,6.
01:17:00386, 36.
01:17:0136.
01:17:02Um
01:17:04O.
01:17:05IEV upon our original formula.
01:17:079000 to 36.
01:17:09divided by 250 microAM.
01:17:10The answer, what should happen?
01:17:12250 microAM.
01:17:14My dear, dear, dear, dear, very important MCQs in the past.
01:17:19When current I flows through a wire, the drift velocity of the electrons is V.
01:17:27When current 2 I flows through another wire of same material having double the length and area of cross section, the drift velocity of electron will.
01:17:42There is a drift velocity.
01:17:44In a conductor, the electrons are flowing in a conductor.
01:17:47So, the velocity is called drift velocity.
01:17:50This formula is called velocity equal to current divided by n charge density.
01:17:55This is the charge of electrons.
01:17:57This is the area of conductor.
01:18:00Now, what is happening?
01:18:03The velocity was at the beginning.
01:18:06But we have said that we are going to talk about another conductor
01:18:09in which the current came.
01:18:11So, the value has doubled.
01:18:13Okay.
01:18:14Okay.
01:18:16And what is happening?
01:18:18Of the same material having doubled the length.
01:18:21Length is not in this formula.
01:18:23So, there is no difference between the length.
01:18:25An area of cross section.
01:18:27Let's go.
01:18:28Area of cross section has also doubled.
01:18:29This is the case.
01:18:30How much drift velocity will be?
01:18:32So, I will roll the mass.
01:18:332-2.
01:18:34It will be cancelled.
01:18:35So, there will be more.
01:18:37So, the answer will be V.
01:18:39Then, the term velocity of electron in a wire of radius R is proportional to.
01:18:46R, R square, R cube.
01:18:48According to formula, of course, none of these.
01:18:51Now, R is formula.
01:18:53I have remained R is not in R.
01:18:54So, the question was also in MD-Gate 2013.
01:18:56Electrical heater can be represented.
01:18:59Has two resistance of R1 and R2.
01:19:05And two switches S1 and S2.
01:19:09The resistance R2 is greater than R1
01:19:12This diagram is very good.
01:19:14Now, what are we going to do next?
01:19:17When switches must be closed so that the heater produces maximum possible power and the minimum non-zero power.
01:19:27So, option is this way.
01:19:29Maximum possible power for option A, S1 and S2.
01:19:34And minimum non-zero power for S2.
01:19:38Then option B, S1 and S2.
01:19:42Maximum possible power for maximum non-zero power for minimum non-zero power.
01:19:49Maximum possible power for minimum non-zero power for minimum non-zero power for maximum non-zero power for minimum non-zero power.
01:19:59Now, this is the explanation.
01:20:02Power of the formula is v2 upon i.
01:20:06Okay?
01:20:07We say power maximum power for minimum non-zero power for minimum non-zero power for minimum non-zero power.
01:20:14Which happens for parallel resistors.
01:20:17Power is minimum for maximum resistance which is R2.
01:20:25Here I am coming.
01:20:28Now, see.
01:20:29Power minimum when will be minimum power?
01:20:31When resistance will be maximum R2.
01:20:36So, one thing must be closed.
01:20:37When the switch must be closed.
01:20:38So, that heater must be closed.
01:20:39So, if minimum power for minimum and maximum power for maximum power for maximum power for maximum power for maximum power.
01:20:44So, the correct answer will be option A.
01:20:49Which is very heavy.
01:20:50So, if minimum power for minimum power for minimum power for minimum power for maximum power for maximum power.
01:20:56So, the correct answer will be option A.
01:21:01So, it is very heavy.
01:21:02It is very heavy.
01:21:03For the concept, it is so heavy.
01:21:04I have to be a very heavy.
01:21:05There is also very heavy.
01:21:06The last question is.
01:21:08A and VAR bulb connected in this series.
01:21:13with 40 volts on battery and a bulb C is connected with a 40 volts battery glow of bulb will be well
01:21:28question is that we have connected series 40 volt battery and bulb C connected to 40 volt battery
01:21:40so what do we have connected to a and B and C is different so the correct answer is that
01:21:50A and B same and C is different. The final reason is that we have connected to a and B
01:21:55in series. So in series of resistance, the resistance will increase and add up.
01:22:04When the resistance becomes more, according to Ohm's law, current will be less.
01:22:12So how much voltage is? 40.
01:22:15Equal to IR.
01:22:17Current will be less.
01:22:22And when the voltage starts to drop, the power will also drop.
01:22:27Less power will consume.
01:22:29A and B, C will be less.
01:22:31So C will be less, then A and B will be less.
01:22:34Who will less, which will be less?
01:22:37This or not?
01:22:38I have asked many reasons, which will be same?
01:22:43So A and B will be same, C is different.
01:22:45So this is why we will keep track of A and B.
01:22:48So A and B will be in series.
01:22:50So what will glow also be same?
01:22:52So the answer will be your option number.
