This black screen concept is so cool and it even does not effect our eyes also. Great Sir

you are the most underrated teacher on youtube

I don't know why this channel is underated 😑.....so simple and easily understandable ❤️🙏concepts and easy to visualise

सर आपसे पढ़ने के बाद सारे doubt clear हो जाते हैं। इतने अच्छे lectures देने के लिए thanks.

After physic wallah u are best teacher for me tq 🙏🙏sir

Sir kash mujhe aapka channel pehle se pata hota to main electric feild or electrostatic force and coloumbs law bhi parrh leta overall thank you sir lot of love from pakistan

Sir, the video is extremely well explained and the diagrams are also clear *THANKS A LOT SIR*

God give you lot of energy, and life . Please keep on doing such videos. If you had come earlier my life would have been different

Best channel but underrated the teacher is very polite and kind hearted

this channel should really have more subs,they teach so much to the point,better than many channels who spend hrs teaching the same topic in such a lenghty manner ....exam ke pehle yeh sab videos bohut hi kaam ata hai

Sir u r superb. U helped me to understand physics in a very easy way

Thank You Sir, Aap bahut a66e se #Samjhate ho, Dhanyavaad..😍😍😍🙏🙏🙏

Come here directly from Physicswallha !!!

Sir may pn junction ki purani video abhi hi dekh raha tha aur ye naya video aa gaya love you sir

Through this u I understand much..... !! Thanks 👍SIR

Sir, Holes dosen't move they just only occur , when there is an vacancy for electron..., Only Electrons move

that trivalent accepted negative and became negative. and pentavelent which gave became positive was near junction. And trivalent which became negative near p side of junction do not allow further electrons to come and repels it This was very much needed. Kept on thinking and by your that insight of that idea got to know. May be wrong but got some what clarity almost... But still more trying more and more clearer... no need of conventional current direction i guess... But may be useful somewhere donno but it should be changed if nothing...

Excellent explanation, i was thinking ,ehere would be drift of electrons and holes in unbiased condition, either it will be in whole pn junction diode or in only depletion region where electric field is set, i learnt here that it happens only in depletion region because electric field is set only there

Congratulations for 1 million subscribers after long time ♥️

Ultimate explanation ....! Thank you so much sir ...! :-D

Sir superb and unbelievable teaching.

Sir you are brilliant teacher for phuysics

Thank you very much...I wasn't able to understand this concept earlier but now I got it... Explanation was really helpful was interesting 💕🙏🏻

u r great teacher in world sir. I learn more things from u. love u sir from our family. thnks again.

Cleared all comcepts ✨

Thanku very much I wish millions of subscriber
