Wow!!!! Thanks!!!💜

[@electrical4you]

@@25-anishaherala83 No worries at all Anisha! 🙂

[@BalwinderSingh-cw8zc]

Very nice

[@chetanreddy106]

Too much excellence in the video,and the thing which I found funny is the doll which is explaining has kept the face as an annoying teacher that made me to listen whole video😂😂

[@electrical4you]

Thank you for your kind words Chetan! Very happy to hear you enjoyed the video :)

[@Tagan672]

5:04
in indirect gap semi-conductor, the maximum level of valence band and minimum energy level of conduction band, *do not occur at the same momentum of electrons.* What do you mean by 'do not occur at the same momentum of electrons'? Electrons isn't a unit of measurement?

I'm completely losing her around this point. It suddenly becomes all garbled!

What is the volts used for PC cases? The one you see in the front panel for the reset switch and hdd light

[@markandeyagupta8530]

A different way of explanation & good too. Thank you.

Fantastic explanation!

[@lallulallalla]

mast...it was what i want. thanks a lot of.

[@n1pster3]

At 0:44 you explain anode vs cathode. I believe you have it backwards, isn't cathode the positive terminal while anode is the negative terminal?

[@darth1311]

no

[@vedantsuryawanshi2920]

Very much useful content !!! 😀😀😀

[@kingpetra6886]

Since momentum is conserved, a photon must be released in order to maintain this conserved momentum in an LED? More importantly why isn't momentum conserved in the other types of diodes? What is it about their gaps that cause this? If the momentum of an electron wasn't conserved so what, but a photon where momentum is not conserved?

[@sumeshchakwarty6057]

Perfect for my requirement. Thanks a lot.

[@electrical4you]

No problem Sumesh! Happy to hear you found it helpful 🙂
