I am just fortunate to find such an extraordinary teacher.......huge respect

[@MJ-kv8vb]

Sir why you are saying thanku at last...instead of that we should give thanku to you that you give such a good teaching without any cost...

[@srividyan2600]

Simple and easily understandable explanation...... Thank u very much..... Expecting more videos

[@bas5rocker311]

Thankyou sir! I always hated this chapter but somehow you made it bearable!

[@damnastha4523]

God of physics✌️

[@lizamanik9875]

For the very first time I understood semi conductor so easily thanks to you sir😊😀😀😀😀😀

[@npandiyaraja7697]

I fall in love with semiconductors.☺.... Because of your great explanation 👌👌👌

[@padmavatibhat4409]

sir now i understood what i did in physics lab

[@sattwamabasu2737]

Yeah me too ...

[@artist_vru5hti]

Thanks a lot sir While studying from text I was not getting the concept clearly but after watching your video, I've cleared all my doubts and understand properly.🙏

[@behararakesh3275]

Obviously superb sir nice explanation sir , definitely useful to us a lot .. thq so much sir

Sir difference between avalanche breakdown and zener breakdown?

[@RahulYadav-si5pq]

You looking very nice bhai

[@harshchauhan3714]

Avalanche breakdown is known as zener breakdown

[@nityanandmishra9406]

No there is a difference between avalanche and zener break down....

[@Ok-bw9zv]

They both are same

[@DJ-xx2wx]

Sir could you please make vedios on op-amp

[@naeemabbas7294]

Thnxc sir g.. Butbin reverse bias initially current increase with increasing voltage... But when we increase Voltage further then depletion region increased and it becomes insolator then current become zero and.... Help any one if it will possible

[@mayankchandwal792]

Because in reverse bias the current is due to minority charge carriers whose concentration is about 1ppm .Initially the current increases and then it becomes constant at a avalanche voltage due to an ionisation of minority charge carriers there is an abrupt increase in current due to an increase in concentration of charge carriers. I hope this will help you .

[@bhagyammabhagya1521]

How barrier width become constant in reverse biasing in order to create a high electric field

[@sattwamabasu2737]

Barrier width is the distance between two oppsitely charged plates as in capacitor .In this case barrier width is the width between p and n sides .It can extend upto a certain limit ,i.e. , the length of the diode . E(electric field)= V(voltage across the two points in thr circuit)/ d(barrier width) Since with the increase of voltage the barrier width increases ( as neutralised atoms add up to the potential wall) the ratio of V to d remains constant and hence E reamins constant.😀

[@jayantachakraborty276]

nice..

[@trivenisaripudi2000]

Niceee

[@meganathmeganath1742]

Sir how are you saying there was no 4 th chare carrier

[@samriddhikhandelwal9641]

When depletion region increases than the electric field increases or decreases

[@chinmaylute1571]

E.F will increase

[@salwaaltahir988]

e.f= v multiply d in reverse biasing the depletion layer widens hence d(distance) increases thus electric field increase.

[@ashokgajawada8437]

Why atoms are ionised in which region

[@dr.jaikumarsharma9714]

🥇🥇🥇🥇🥇⭐⭐⭐⭐⭐♥️♥️♥️♥️♥️

[@manoj6804]

How can d be constant when v is increasing. d will also increase or decrease by changing v.

[@sampathkumar9980]

Sir what is negative voltage what is the meaning

[@sattwamabasu2737]

If we consider the voltage in case of forward bias positive , the voltage in case of reverse bias is in the opposite direction and hence we consider it to be negative .The + or - sign denotes the direction of potential .

Sir, current is flowing from positive point to negative or from positive point to negative point? Please clarify sir.
