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,

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

06:34it will be PNP or NPN, if any of the two is yours, then it will be PNP or NPN, if any

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

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

08:04yours, then it will be PNP or NPN, if any of the two is yours, then it will be PNP or

08:24NPN, if any of the two is yours, then it will be PNP or NPN, if any of the two is yours,

08:44then it will be PNP or NPN, if any of the two is yours, then it will be PNP or NPN,

09:04if any of the two is yours, then it will be PNP or NPN, if any of the two is yours, then

09:26it will be PNP or NPN, if any of the two is yours, then it will be PNP or NPN, if any of

09:55the two is yours, then it will be PNP or NPN, if any of the two is yours, then it will be

10:24PNP or NPN, if any of the two is yours, then it will be PNP or NPN, if any of the two is

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,

12:21if any of the two is yours, then it will be PNP or NPN, if any of the two is yours, then

12:50it will be PNP or NPN, if any of the two is yours, then it will be PNP or NPN, if any

13:19of the two is yours, then it will be PNP or NPN, if any of the two is yours, then it will

13:38be PNP or NPN, if any of the two is yours, then it will be PNP or NPN, if any of the
