[@aslampt1982]

The consant "k" in the equation k=11600 by eta is not Boltzmann constant. k=q/K........capital K is actually the Boltzmann constant

[@i_m_hk]

Yes thanks

[@atheunboxer143]

Thanks bhai for clearing my doubt.

[@omagency2771]

These lecture is very good and help me a lot and also saving my degree

[@chanchalkumargupta2385]

Watching from Australia..
Awesome..

[@tanishqsangwan]

Speedrunning whole playlist the night before exam at 2x speed >>>>

[@bishaldalui]

you are awesome sir.

[@aryandhakad8495]

I m following your playlist completely and I'm watch videos with 1.75* speed 🙄😂😂

[@RohitSingh-dj6uy]

Me with 1.25 speed 😅

[@rufussewel4553]

why i don't apply this earlier? f**k it's so effecient

[@KartikSharma-ri8ok]

Me. 2x..😂😂

[@aryandhakad8495]

My exam has done 😁😁😁

[@yamunasailada3060]

Me watching it in 2x 🤣🤣

[@etneide]

Can't we say that the current is, generally, equal to ID = Im - Is and in case of reverse bias, being Im near equal to zero, then ID = -Is giving us the current direction too?

[@Fighter_Believer_Achiever]

Thank you very much sir🥳🥳🥳🥳

[@alterguy4327]

You are awesome sir☺

[@CSE_11]

Thanks 😊

[@mritunjaysharma7516]

very good lecture luv u sir

[@capitalistbabu1154]

please provide us more notes on analog electronics chps oscillators ic 555 timer etc

[@dwinovianto1250]

7:29 What did you mean Id = low or high?
When is it low & high?
thanks anyway

[@omar.khannn]

thanks for this sir, do you have a video for THYRISTOR as well?

[@cleoseta6264]

The kn = 11600 part makes absolutely no sense to me.

[@deepikadeepika8595]

Sir, shouldn't we take all the units as same an then do it?

[@g7sky]

Respectfully, please explain why or where does the minus 1 comes from in the formula for current through the diode ? thanks

[@sparrows3147]

when vd =0 the exp term becomes zero ,then the only current is saturation current (Is*1)

[@blackvalley2504]

Sir,how can there be reverse saturation current in forward bias?

[@raimaghosh1337]

Reverse saturated current is temperature dependent. So no matter what bias you apply a feeble amount of current (opposite direction to FB current, & same direction as RB current) will be there.

[@learnphysicsandmaths4444]

Sir in this question germanium ka to Vb hi 0.3 v hota hai aur hum 0.25 V de rahe hain to current to flow hi nhi hona chahiye

[@AvdeshKumar-hc1pz]

Sir reverse saturation current and drift current will be same ??

[@adityasaini6507]

nhi diya sir ne ans?

[@dhruv6102]

sir why didn't you converted milliampere into ampere in question of reverse saturation.

[@harihara.t]

diode current is 10mA here,but you took it as 10 A

[@charankumar4267]

He took as 10ma only at last he took answer also in ma

[@juliethmelado]

Good day sir. Your current direction is same as the hole current?

[@preetishsajwan4502]

Saturation current is nothing but drift current right?

[@akhileshkumarsaket7714]

Thank you sir

[@lewllewl3911]

Don't we have to convert the mA to A?

[@josephalias5671]

yes

[@muhammadfarhankhalil8195]

It also depends on the question I think so

[@riazahmedrakin5866]

If you put the value of ID in mA you will get the value of IS in mA,same goes to using Ampere unit.

[@KaveeshaKavinda-jj5zz]

why get 10A instead of 10mA diode current ?

[@tps8470]

Nice

[@zeevlogs4250]

Thanks Sir!!!!

[@siddhantkumarsinha6183]

Hello sir, small doubt. If diode is open circuit when reverse bias voltage is applied to it. Then what exactly is reverse saturation current because when it is open circuit the current should not flow right.

[@azmainfaiak8111]

That is for the ideal case.....in ideal case no current should flow......but irl a small amount of current flows in reverse bias condition before reaching the breakdown point

[@pujabiswas4062]

thanks sir

[@prabalsharma4855]

doesn't the expression for Vt here , contradicts the expression for Vt in lect 10 (barrier potential) there it was Vt= (KT)/q and here it is rep as Vt=(T) / Kn, how?

[@i_m_hk]

K =11600/n , here K is normal constant not Voltsman constant (k).

[@sanepallisaikiranreddy9117]

What is Vt here..u could not mention here..give some clairty

[@mamekuti4044]

Where do you guys study this?

[@Osmanity]

this book goes into detail of all electronics with not hard English and diodes that he explained. The book is called "Electronics a system approach "

[@Dontever_throw_trash_out]

PLS GIVE LINK TO GET SCIENTIFIC CALCI FROM NET

[@juliodelmonte4496]

Notice that it's not specified if he's using conventional flow or electron flow

[@aniketyagik6528]

Sir English subtitles kyun rakhe h inhe hata dijiye its so irritating

[@mritunjaysharma7516]

sir semiconductor 20 rupe ka mil jayega sir ?

[@akhilsharma86]

Sir can we use two semiconductor instead of a diode

[@sudhamsr2676]

wt abt -1 in diode equation

[@lostInTracks]

please correct the ans in last, you have taken mili ampere two times.

[@sparshpasricha6938]

Vt ka mtlb???

[@_gauravsharma_]

Thermal Voltage. Also called "Voltage equivalent of temperature".

[@diptiprakash6717]

Thanku sir

[@Kashyap.gameplay]

2x speed and still seems normal

[@csetankalareshma]

Hw many of u r watching before exams😂😂😂

[@Amankumar0505]

kal hi exam hai🙃

[@harshaddhokne4487]

is saturation current and drift current same?

[@marked3382]

The drift current which comes from the minority carriers is called reverse saturation current

[@tumwesigyebrief7101]
