00:00Welcome all of you to this channel with one more educational video from a new educational video

00:11So, let's go to our note pad and learn something new today

00:20Four students set up the circuit

00:22Four students experimented with Ohm's law

00:27and connected the circuit like this

00:30First student connected like this, second student connected like this, third student connected like this and fourth student connected like this

00:39In this we have to tell which of the following option is correct

00:44or which child has connected the wires correctly

00:50First, let's look at the thick ones

00:52As we look at each one

00:54We can also consider this to be correct for a while

00:56But we can't consider this to be correct because he has connected all of them in series

01:00In this, they don't connect in series

01:02This is wrong

01:03Now, if we look at this

01:05What has he done?

01:07This is positive and this is negative

01:09This is correct, but the current is flowing from here

01:12So, this is negative and this is negative

01:14Whereas, the current should come from here to here

01:17So, this will also be wrong in this

01:20Now, we come to this

01:22What is this?

01:24The child has connected it correctly

01:26But what has he done?

01:28He had to connect the voltmeter in parallel order

01:30He has connected the ampere meter in parallel order

01:34So, what is this?

01:50Let's write it like this

01:52First, let's erase this

02:05Hindi medium

02:07We will write this in Hindi language

02:09Language doesn't make much difference

02:12We also studied in Hindi medium

02:15The main thing is that

02:17Your concept should be clear

02:22Parallel combination

02:24Correct circuit

02:26Circuit setup

02:36Observe the following incomplete ray diagram of an object

02:44Where image A'B' is formed after refraction from a convex lens

02:55You can see that this image is upside down from the convex lens

03:00First, we have to complete this figure

03:05As we all know

03:07There are some rules of ray

03:11Whichever ray comes from the principal axis

03:14This state comes out

03:17And from its end point

03:20If we remove one ray from here

03:24Then its position comes here automatically

03:28Now, how does this ray go?

03:31Because the figure is on the left side

03:35So, we have to move from right to left

03:38Because we have been given in this way

03:40So, we pass one ray from here

03:45Obviously, it will go here

03:49Like this

03:51It came here

03:53Now, at this point

03:56There is an object

03:58Image is A'B'

04:02So, we show its object from A to B

04:06This is our object

04:10Here, my space is less

04:13You can understand it like this

04:16Still, the figure is clear

04:19I write this

04:21A'B'

04:23So, we show it from A to B

04:25A

04:27AB

04:29This is our object

04:31This is AB

04:33Now, one ray will go straight from here

04:37From its main point

04:40And the ray which goes straight

04:43From that lens

04:46It will turn towards the focus from here

04:50So, it will come out like this

04:54Like this, our diagram is complete

04:59This is my picture

05:02You can manage it

05:04Still, the correct diagram is

05:07It will be complete like this

05:09One ray goes straight

05:11You have to make it straight

05:13Because it is colliding with the lens

05:15After colliding, the ray will turn

05:17Where will it turn?

05:18It will turn towards the focus

05:20One ray will go from here

05:22It doesn't have to turn anywhere

05:24It will go straight

05:26The intersection of these two points

05:29It will intersect at some point

05:32So, it will be the same point

05:34Where the image is being formed

05:37We have been asked two questions

05:40We were also asked this question in Viva

05:43In Physics

05:45Maybe, such questions are asked

05:49What is the position in this?

05:51The position of

05:53The position of object A would have been

05:57Where would be the position of A?

06:00Behind

06:02Behind 2F

06:04We will write it behind 2F

06:07Behind 2F1

06:13Behind 2F1

06:16From 2F1

06:19If we want to write in Hindi

06:22From 2F1

06:25Here is the right

06:28Here is the left side

06:30Left side

06:33Left

06:35Side

06:37Side

06:39Now

06:41Size of

06:43Size of the object

06:46Would have been size of

06:48As you can see

06:50The size of the image is very small

06:53And the size of the object is big

06:56Size of the object

06:59Would have been

07:01Bigger than the size of the image

07:06Bigger than

07:08The size of the object

07:10Would have been bigger than the size of the image

07:14If you had asked the question in Hindi

07:17Bigger than

07:19Bigger than

07:21This is a small question

07:23And that's the end of this episode

07:26This episode ends here
