[akshayarl]

Thanks for ur valuable lecture sir....🙏🙏🙏
I understood the concepts very well....🙂🙂🙂

[Ginger_Cattt]

You r doing a great job sir. It was very much helpful. Thank you soo much!

[MahiJaan]

Thanku soo much sir. this concept i understand clearly

[shaikthajwin]

Thank you sir.your explanation is fantastic and this video is amazing as like

[madhavan.j]

So basically notes are being read aloud nd it's known as explanation. I don't know how others are saying that the explanation is good, amazing and too understandable.

[Reshma-dzcr]

Very useful information sir I understood very well tq for your vedio sir

[ravinasewatkar]

Thank you sir for very knowledgeable video.👌👍👍

[gadhamshettysanjay]

Thank you so much sir this concept I understand clearly

[vandanapunamruthasai]

tnx sir for ur explanation and explain (UNIVERSAL SHIFT REGISTER)also sir ones

[ramyasree]

Thankyou for this video sir, everything was clear, it helps me a lot❤️

[shanuuzzzvlog]

Thank you sir for the clear presentation

[sushilkerketta]

It was nice clss
Easy in understandance

[spicesweet]

Thank u so much for sharing this video it is very useful

[islamicguidence]

Thank you so much, sir....very good explanation.

[galatapori]

Its nice and clear explanation useful to me

[asokkumar]

Due to minority carriers (-) in p- side recombine with minority carriers (+) in n side.
Minority electron from conduction band recombine with holes in valence band.

[rohansamrat]

thanks sir ❤️, for best explaination 👍😊

[wqnmlcq]

Good and simple. Electrons jumping from conduction band to valence band need little more explanation
