BJT transistor NPN & PNP working difference, in Hindi

BJT Transistor working, NPN & PNP transistor difference, function, and principle are explained in Hindi in the video tutorial. The difference between NPN and PNP Bipolar junction transistors is explained.
In the Lecture, BJT transistor as a switch circuit and BJT transistor as an amplifier are explained.
Noise pick up is shown in the demo, Experience-based BJT circuit design tips, the application of an amplifier, noise pickup by transistors, how to suppress noise, and faster on-off operation, are explained.
Educational tutorials 49 by G K Agrawal (Gopal Krishna Agrawal) on electronics engineering in Hindi.
The lecture is given by me based on my industrial experience and is useful for electrical, electronic communication .and power electronics engineering students.

[@pankajpushpakar7351]

sir, mere kuch2 doubts clear ho gye, aapke tutorials dekhne k bad, lekin kuch2 doubt abhi bhi hai mere ko, jaise noise suppression k liye jo resistance use kiye hai wo 10k ko hi kyu use kiye hai ?

[@pankajpushpakar7351]

jab bhi koi project bnate hai to kaise decide krte hai ki kaun se no. ka transitor use krna hai ?

[@GKAgrawal2]

You can use here 20K also. However this is decided based on long experience. In some products I have used 100K, some other place I have used 1K also. It is not just theory based.

[@GKAgrawal2]

WE should know various current, voltage, power loss, response time, quality, reliability requirement etc, then we have to select. But in Industry, this is again selected by experience and theory both, not only type number , but also manufacrer name also. Please note that selection of component in project in BE, in commercial product, in industrial product, in military produc etc is different is not same. For example in fan control, you want cheap component and if it fails then no problem. But in airoplane design, you want best quality , you can afford failure of transistor, & you can pay more money also.

[@meetpatel8197]

really good work sir. i did not get why diode is used so please if anyone can explain me it would be great

[@GKAgrawal2]

Diode is used for different purpose at different place. Some of the use are explained in my 6 videos, Igbt rectifier, 20 tips for circuit design, 20 tips for electronics protection, Smps block diagram, mofet testing with multimeter, diode clamper circuit.

[@meetpatel8197]

[@GKAgrawal2]

This will avoid reverse voltage appearing across transistor BE juction, hence protect it.

sir , how u create the negative supply to trigger the base of PNP transistor.

[@GKAgrawal2]

1- No negative supply required for PNP.
2- If base voltage is less than Emitter then it will become ON.
3- Connect Emitter to plus terminal of supply.
4- Leass than supply voltage at base will make it ON. THis ckt is shown video.

[@ajitsingh-xv3lg]

hello sir,aapka sara video bahut achha hai.but mera ek question hai ki resister ko kaise select karate hai ki kitna ohm ka register lagega .kahin 10k ka hai kahin 4.7 k ka hai ye kaise select karte hain.

[@GKAgrawal2]

Resistor ko kahee per calculation se select karte hai , aur kahee per experienc se. Aur experienc ke bina to calculation bhee kai bar kam nahee karta hai. LED ke series me resistor current flow ko limit karne ke liye lagaya hai. Yeh calculation se hai aur experience se bhee, jaise kitee current se LED me dekhane ke liye light ayegee. Base mey resistor experience se lagaya hai.

[@ramgopalverma1987]

Sir aap ka javab samza nahi kayo ki Om ka niyam se hi kam karta hai

[@goldenzia667]

Sir transistar ko splai ki dar say deni ha emitter say ya collector say

[@GKAgrawal2]

npn transitor mey supply kaa positive collector ki taraf, pnp mey supply kaa positive emitter ki taraf. Circuit diagram mey mainey yeh bataya hai.

[@taplalverma6853]

Emitter में maximum कितना वोल्टेज दे सकते है

[@amitghosh6966]

If I use Bc547 whose collector current is 100 mA & beta is 100, how much beta to consider if I want 80 mA current?
2) If I use Sl 100b transistor whose collector current is 500 mA, beta is 50, how much beta to consider if I want to draw 300 mA for making small regulated power supply?

[@GKAgrawal2]

no change in beta

Jesse switch me NO NC type Aata he. NO type switch normally open hota he. NC type normally closed. Transistor me base ko pe+ , ne- dene par voh collector Orr emmiter ko short karta he matlab transistor NO type hua. Fir voh npn ho ya pnp.
But emmiter or collector normally close chaahiye or base me +/- dene par voh emitter or collector ke bich ke current ko open Karna chahiye.
Toh aisa normally close transistor available hota he? Sorry me mechanical Engineer hu. No electronic deep knowledge. Would like to make you guru 🙏🙏🙏. And learn all you have.

Yesa circuit ek aur not gate base mey laga kar bana sakte hai.
