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
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...
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
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
Dil se very much THANK YOU Sir, Aapke videos bahut acche hain aur humare exams k liye bahut helpful hain.. Kindly aise hi videos banate rahe, God Bless you.
Why the holes are electrons are combining here why they are making charges When a side of postive charge carrier is there and vice versa is there they must combine right ?

I have no doubt about p-n Junction after looking your video.... So many many thank you for Your helpful discussion about p-n Junction . From :-Bangladesh . Ssc student.
These lecture is very help full to understandble explanation and u can create own definition ,examples, relation to each other etc. All quality contained is here ❤
Sir how a hole can move as it just a blank space for atom ..pls clarify will it shift or move ya whole atom consist of of hole containing shell will move
Sir, Everything is perfect and a personal suggestion or request was there.please don't promote your another video in middle of the video. While getting concept it creates a lot of distraction. Thank you 😊❤️
Sir, Jb electron n-type se p-type k side diffuse krega tb holes bhi p-type se n-type k side kyu diffuse krega. Aisa kyu nhi hoga ki electron p-type k side diffuse ho aur holes ko fill kr de and Dono k charge neutralise ho Jaye. Ya phir holes n-type k side diffuse ho aur electrons k sath mil k neutralise ho Jaye. Please reply sir
Sir i have doubt,why did holes jumps to n side,if n-side is already fullfilled of electrons and only have free charges which could go to ocvupy holes space
Sir hole ka move krta hai? Hole toh imobile charge carriers hote hai ...electron usko aake fill krta hai ...or jab electron ek gajah se dusre gajah jata hai toh jha se wo aata hai wha hole creat ho jata. Hai
You are my best teacher thanks alot.... Very beautifully explained lecture.... You clear the basic concept of the topic very easily and in a simplified method... Your methodology is so beautiful that no words to explain the beauty of you lecture.... Thanks alot....

If there are diffusion current and drift current which are opposite to each other, how do net electric field and potential barrier established at equilibrium??
Due to differences in Fermi level, yes diffusion did made potential barrier neutral but due to the difference in Fermi level it creates a potential difference

This black screen concept is so cool and it even does not effect our eyes also. Great Sir
Because the white stop was small
And saves battery life
Ja bat bikkul sai ha
And makes easy to memorise
Sorry but I think that you are wrong that black does not affect our eyes.

Sir, Holes dosen't move they just only occur , when there is an vacancy for electron..., Only Electrons move
Hmmm Ok 😊
First you have to watch previous video, then come to share your knowledge
Why the holes are electrons are combining here why they are making charges
