00:00As-salamu alaykum.
00:03Today's video is very useful.
00:06But the problem is that you won't be able to watch it.
00:09It will be a long video.
00:12But it is a useful video because
00:14the work that an electronics enthusiast does,
00:18the work that a catering enthusiast does,
00:20it is very important for him.
00:22It is a basic work.
00:23What I am doing is basic.
00:25I will try to explain it to you in a good way.
00:28See, this is a transistor.
00:31There are many types of transistors.
00:33There is not just one.
00:35There are many types.
00:36See, I have kept them in front of you to show you.
00:39See, this is a transistor.
00:43But if you go into its theory, it will be very long.
00:46I am only telling you this because it will be a little work
00:49so that you can work.
00:51This is also a transistor.
00:53Okay?
00:54And this is also a transistor.
00:57And this is also a transistor.
00:59This is also a transistor.
01:01I have shown you all these transistors.
01:03It can have more types.
01:05But there is only one principle to work.
01:09It has two types.
01:11One is PNP.
01:13NPN.
01:14There are two types of transistors.
01:16You have to check them.
01:18I will tell you.
01:19And I will try to explain their function to you in a good way
01:22according to practical theory.
01:25And I will explain it to you very briefly in a good way
01:29as to how you can work with it.
01:32It is not beneficial for me to watch the whole video.
01:35I am talking for your benefit.
01:37If you understand what I am saying,
01:39then you can watch the whole video.
01:41First of all, this is a component in my hand.
01:45This is called a diode.
01:47These are small and big.
01:49See, I have put one here too.
01:51It is small.
01:52But I have kept this big one so that you can understand it well.
01:56There is a theory in this that
01:58its main thing is that
02:00you see its symbol.
02:02Give me a lead pencil from above.
02:04Lead pencil.
02:06Its symbol is like this.
02:10This is like this.
02:12And see this.
02:14Like this.
02:16I have made a video on this.
02:18I have explained it in great detail.
02:20You can watch it.
02:22But since it is related to this,
02:24I will explain it to you again
02:26so that you can understand.
02:28Only for this.
02:30Otherwise, it had no purpose.
02:32Look at its main thing.
02:34You can show the camera.
02:36Look at this.
02:38This is its symbol.
02:40Look at this.
02:42There is a lead pencil here.
02:44I have kept it like this.
02:46Its purpose is that
02:48I will tell you briefly about it.
02:50Not much deeply.
02:52If I take it from here.
02:54These are meter probes.
02:56Look at this.
02:58This is negative.
03:00This is positive.
03:02This is positive.
03:04It is attached like this.
03:06If I do it like this.
03:08Look at this.
03:10There is a line here.
03:12And I have put a line here.
03:14If I take it from here
03:16and give it positive voltage
03:18on this side,
03:20so it will cross it from here.
03:26If I give it negative voltage
03:30on this side
03:32and give it a negative voltage on this side
03:34so it will cross it from here.
03:38And if I give it positive
03:40on this side
03:42a positive line, then it will not pass. Similarly, if I give a positive line from this side and
03:49a positive line from this side, then it will not pass. This will be its theory. Now I will
03:58tell you its practical by checking it. How is it checked? We have put this meter on buzzer
04:08like this. If I check it like this, it should not be shown as short. If I put it on diver
04:15mode, then it is a positive line. If I put it like this, then it is showing a voltage.
04:27If I put it on diver mode, then it is showing a voltage. If I put it on diver mode, then
04:34it is showing a voltage. If I put it on diver mode, then it is showing a voltage. If I put
04:41it on diver mode, then it is showing a voltage. If I put it on diver mode, then it is showing
04:48a voltage. If I put it on diver mode, then it is showing a voltage. If I put it on diver
04:55mode, then it is showing a voltage. If I put it on diver mode, then it is showing a voltage.
04:59If I put it on the 15 volt mode and put it on the 5 volt mode and then put it on 20
05:03volts mode, then it is 100 ohms. Simple. If the switch is on, then it will not be generating
05:10at all. If the switch is off, then it will start generating at all. The secret is if
05:17So, if you take any transistor, PNP, NPN are later, first of all, if it has a leg like this,
05:27one here and one here, in this, this is the emitter, this is called emitter, in the center
05:39it has a collector and this is its base, base collector emitter, in the same way, whether
05:47it is PNP or NPN, whether it is PNP or NPN, if any of the two is yours, then it will be
06:04PNP or NPN, if any of the two is yours, then it will be PNP or NPN, if any of the two is
06:14yours, then it will be PNP or NPN, if any of the two is yours, then it will be PNP or NPN,

06:44of the two is yours, then it will be PNP or NPN, if any of the two is yours, then it will
07:04be PNP or NPN, if any of the two is yours, then it will be PNP or NPN, if any of the
07:24two is yours, then it will be PNP or NPN, if any of the two is yours, then it will be

10:53yours, then it will be PNP or NPN, if any of the two is yours, then it will be PNP or
11:22NPN, if any of the two is yours, then it will be PNP or NPN, if any of the two is yours,
11:51then it will be PNP or NPN, if any of the two is yours, then it will be PNP or NPN,
