Class 12 Semiconductors: We cannot imagine our life without computers today. But what makes a computer tick? What's making this technology grow at such an exponential rate? It's all due to semiconductors. As unbelievable as that might sound, altering the properties of semiconductors allows us to build these computers. In this topic, we will explore the world of semiconductors. It's a journey from what semiconductors are all the way to creating building blocks of these computers.

I love that "Tadaaa......n"sound when ever you draw a figure or complete an equation. It just show how enrolled you are while teaching.😇😇
Sir I just say that u deserve a Nobel prize ... for heartfull service to students ...🙏🙏🙏🙏🙏🙏🙏👌👌
The way u taught current gain is just mind blowing
I really really wish I had teacher like you in my school days. In my school I was very much interested in electronics. So I took Electronics instead of Biology in my 11th and 12th. But in my two years of struggle I never really understood working transistor. Without understanding working of transistor understanding other electronic circuits was really burden to me. Somehow I cleared my elecronics course but I turned away from electronics engineering in my graduation. I did my graduation in mechanical engineering because it was more intutive. After my gradution I secured All India Rank 1 in GATE exam. If I had teacher like you , I could have done wonders in electronics engineering because I had natural inclination towards it. You have done really nice work to explain the complex topic like transistor without going into details of quantum mechanics. I request you to make videos regarding other circuits using transistors. It will be helpful to students accross the world.Thank you very much.🙏
I better pay you than my college
Yaa🤣
Completed grad. ? 😂
Never seen a better teacher than you.. .🙌
Is it me only or the graphics are really satisfying?
Your enthusiasm and the way you teach just makes the class so much fun! Really amazing teacher mahesh sir
Thank you so much for this u have answered all my questions
Best teacher ever i face
that was extremely understandable! Thanks in tons!
But I do have a question, Professor, related to the microphone itself, What exactly does my voice represent in a microphone? is it turned into waves? and what type of waves are they? Or is my voice the 0.7 or more voltage? Since one electron flows out of 99 in there, where does this electron go? into the microphone? is it double wired? I am not sure how this whole thing is implemented
If you're a school student or at least not an engineering student it'll be quite difficult to explain, cause this way of viewing a transistor and just this knowledge is like 1+1 in the concept, it's a small building block, you need many other concepts of the transistor to understand how a microphone works. Not to mention, the working of multiple transistors, their connections with one another, and the different transistor types.
*IN SHORT* you can't expect to understand how a microphone works with just this knowledge
Edit: Not trying to make it sound worse, but you also need to learn some signal analysis *then* some random signal analysis too🙂
Bruh it was earthed on the other end
Ur teaching style is so cool...Its better to pay u 🙄
Man u explained this so easily 🎉
Great help for mains bruh
How is khan academy not top 1???online education?
It is.
Best explaination i got so far
U r great bro..
Conceptual clarity superb
Please differentiate the currents respectively, which one is diffusion current and which one is drift current ??
I have no idea why am I paying my college so much
Me too
I hope there will be more videos from you sir
Very nice explanation.
May Allah blessed you and reawrd for that.
Really well taught
Really u r explanation is lucid...u r way of explaining things is highly commendable...thanks a lot....
Sir, why can’t we use the same method to find alpha as that to find beta?
i’ve tried it but, the equation is inverse, is it necessary for alpha to be ratio of Ic to Ie?
Yea
'That's pathetic, why would anyone wanna buy that transitor' lolz my man got triggered. anyway great vid mate, thanks
Thanks a lot !
You made it so simple .
How does some of the electrons come out of Base terminal?
It's connected to positive terminal so electrons are pulled
that’s fire bro …thanks
Awesome job. I got a better understanding of Electron and Current flow.
Mene fazul mein apne sar mein dard kr diya itna acha smjh a rha tha mene apni book (Pakistan) ki diagram se match krna start kr diya without knowing k sir working CE ki smjha rhe hain mein general concept smjh kr confused ho gyi i mean humari book mein pehle working of transistor hai phir ce and cb separate but uff ye gandk diagrams joh humarj book pr bani hain demagh kharab kr diya😢😢
Very nice teacher
why output current is at collector?
Nicely explained 💥💥
Once again thank you!
Great 👏 explanation
you are the best
can we write b as 1-a
👌👌👌 #1
Why emmiter is connected to ground?
Thanks you very much 🐦🐥🐥🐳🐳🐣🐣🐤🐝🐝🌸💮🌼🌾🌻🎇🎇
It's thank
Thanks a lot, sir
BRO THAT'S AMAZING 😎
One question out of topic kya india mein Khan cast paya jata hai. ?
plz more video on 12
Very nice
Super sir
suuuuperb classsss
Sir ,How 5 and 95 electrons injected back to emitter in external wire??
♥️♥️
Once again thank you!
