Perfect! ✨This video is complete with perfect explanation👌No waste talks, no extra unnecessary content, no long boring lecture, each word spoken is limited and more than sufficient. This is exactly what the word perfection means 💯.
This is the best physics lecture that I have seen till now. Straight to the point explanation no waste of time. Moreover the videos of every topics are separate so we don't have to waste our time searching for the topic that we need. Short , simple and beautiful lecture ❤💕 Understood everything . Thank you very much sir. 🙏🙏
Super sir pura samjme agaya sir 3 days I am finding the videos but I not get full details video but apki video mai pura smaj me agya u r the genius sir thank u sir
Sir really ur way of teaching is just another level.U explain each and every thing in a very polite and patient manner.Thanks a lot from all the students whom u teach and we r very grateful to have u as our teacher,sir.🙏🙏.
Sir you are using such a simple language... And most imp thing u are not wasting a single second in jocking around or talking... Thankyou so much sir🧡🧡
Sir i wanted to ask that uh have not uploaded the video regarding to the filter circuits and ripple factor . Can uh please help with that . Thank you so much sir . Your teaching methods are very good .

Sir I want to know the second condition current direction when the current obtained with negative half ? and you explained very well and thank you for being here.
sir i must say you are the best teacher i have ever studied from. Your style of explaining is just awesome.... thanx a lot sir your videos are very much helpful... thank you sir
Sir when an electron left the valance shell and go to the conduction band in case of semi conductor materials, normally we consider that the vacancy of electron is known as hole and containing + charge, and electron have - charge . My question is that if we think about copper 1 atom and after applying voltage the valnce electron flow or left the valance orbit the + charge will be greater than electrons bcoz no of protons becomes greater now what is the concept about the positive charge ????? Is it on whole atom. Or only hole contain + charge???? Plz explain it I will be thankful for your this kindness.
Charge ki bat ki hai , I know conductor material hai copper, silicon germiniam to directly insulator behave krengy impurities waghera k bad extrinsic ye sab I know, mein Jo puchna chah RHA Tha us k ans Ni mila conceptual abi tk, may be koe scientist janta hoga!
Sir , in half wave rectifier , during negative half cycle on inpur , it is possible that there would be sudden increase in current through it as happening in reverse biasing of pn junction diode . Isn't it ??? Plzz explain and reply soon

You forgot about avalanche breakdown which you didn't tell in the last video

If reverse bias is equal to breakdown voltage then the reverse current through increased very rapidly this situation is called Avalanche breakdown

And , awesome teaching...
Yes you are right he had made wrong diagram of transformer
He had made more no. of turns in secondary coil which is wrong

Sir , in half wave rectifier , during negative half cycle on inpur , it is possible that there would be sudden increase in current through it as happening in reverse biasing of pn junction diode . Isn't it ???
Plzz explain and reply soon
No it's not possible. The value of i falls down in reverse bias and it goes into break down where diode will not conduct at all.
