Oh my god what a wonderful videos , sir you are great , this is much more informative than taking courses on some other platforms ,your teaching extremely good 😍😍😘😘😘😘😘😘😘

[@AubaidAhmadWaniGCET--]

At 12:46 in diagram what does Z° voltage represents in the circuit as you draw it's polarity opposite to applied reverse bias voltage ? Also in reverse biasing barrier potential adds to applied voltage....plz reply sir

[@urmilareddy1921]

thanks to u sir and ur academy

[@sanyamgoyal5172]

When you replace zener diode by equivalent circuit as a battery how you decide which terminal should be above ?

[@humaizmalik]

Tomorrow is my semester exam won't be getting F Neso Academy is really life saver! ❤️

Best teacher, thank you!

[@chiranjiviaulakh4744]

Thanks a lot... All i know about rectifiers and diodes is because of you.. Thanks...

[@mohammadalmasrouhy3440]

Amazing lecturer in performance and explaination

[@mohammadalmasrouhy3440]

Very very benefit lecture in fact it gave me more energy in physics

[@LegumeFinder]

the polarity of the voltage is correct except at Forward bias region. please correct it.

[@phanindrareddy4885]

In last circuit How can u put volarity as plus then minus for the vzo But above polarity is negative then positive for diode

[@RahulKumar-oj3cf]

Thanks for the video. It really helped me. Keep up the good work.

[@shailajapal3089]

I have a doubt... when you are replacing the diodes with the battery, you have taken the polarity of battery opposite,i think.. clear it please.. you had done correct or it is wrong because when i solve questions , i always get wrong answers,,

[@mohamedkalith7607]

What polarity are you talking about?

[@hm2715]

In reverse bias ,,,, polarity of diode as taken same as Voltage across it,,, because Reverse diode is nothing but open circuit so the symbol basically represent the voltage across it..

[@viku1807]

yeah i had the same doubt too, i think he got it wrong as in the last circuit he changed the polarity of diode with opp to battery but while writing kvl eqn he treat the polarity as it is

[@sadi3230]

Very well taught THANK YOU SIR..

[@mademguruchakravardhanredd5616]

Excellent explanation Thank you sir

[@akramhussainmohammad7588]

tq for helping real ly a best lecture.thank you once again

[@ramtripathi1621]

At 3:40 i think zener breakdwon occurs due to electron tunneling if i am not wrong. So what does direct rupture means? Can anyone please explain?

Just amazing explination, thank you very much

[@gediondesale1148]

Is zener diode always work in reverse biasing? when it works in reverse bias current not to be zero sir?

[@priyankan1365]

Do you provide any videos on linear integrated circuits ??

[@vishalpal1999]

excellent explanation! Thank you very much for the lectures :D

[@Googleelgoog-q6s]

Sir ,as you said zener diode is heavely doped pn junction diode,and also the depletion region of such heavely doped diode will have narror region,which means the the barrier potential much reduced,then how did you say that in forward bias zener will act as normal diode with 0.7 drop (si) ? Can you please explain i stuck at this for an hour with my friends ..

[@Tk-cr3zr]

he is back. yay

[@ayrutayrut5882]

Genius 👌

[@mareenacijo2508]

why the depletion region smaller....even it is reverse biased

[@bhupendrateriya7630]

Good Explanation

[@yarasinikitha8972]

hello! sir videos are so wonderful really loving it

[@sembiyanpon9483]

Why depletion region is narrow in case of reverse bias.???

[@aditikumari3677]

Depletion region is narrow in reverse bias (of zener diode)as Compared to normal pn junction diodes due to high doping concentration and since the width of depletion layer is small so a high electric field acts (as E=v/x) and the reverse breakdown of junction takes place at a less voltage as compared to other pn junction diodes.

[@raushanpandey6053]

In both the cases,i.e. in avalanche breakdown and zener breakdown there is tearing of covalent bonds bcz of high reverse bias potential, then how they are different???

[@upscphysicscorridor4834]

every lecture is awesome

[@nanireddy601]

In reverse bias you taken Vz=Vzo+IzRz ,voltage difference bw Vz nd Vzo is Vz-Vzo . in current we should take Iz-Izo.... Is it ryt.....?

[@nanireddy601]

Vz=Vzo+IzRz Plz explain me how it is

[@electro-magnetik528]

@@nanireddy601 i think it should be Vz - IzRz + Vzo = 0 please someone confirm.

[@abinayaabi8497]

Sir, Zener diode is reverse biased then how the depletion region of zener diode is narrow

[@agulpofviralthings8742]

Please upload a lesson on varactor diode

[@sumanthreddy391]

anyway the reverse voltage is constant , what about the current , its linearly increasing

[@fatiheneskose4477]

Hello Is there anyone who tell me what is the diffrence between avalanche breakdown and zener breakdown exactly? I undestood that in case of avalanche, electrons gains and electrons break the kovalent, but in case of zener, directly breaks kovalent. Is it true or could you tell me much clear explanation?

[@vanshtomar6527]

Did you get the answer after 4 years.?

[@aashishsahu6694]

Sir make video on all special purpose diodes

[@devimanickam1871]

sir, normal diode also have a breakdown voltage above which the K.E of e increases &results in increased amount of e and conducts current .I have a doubt that why normal diode can't be used for voltage regulation

[@Yoshitha-fq9en]

For a normal diode we has to apply more reverse voltage to get breakdown but for zener diode we can obtain breakdown earlier than normal diode no need to apply high voltage

[@santoshkulkarni3327]

Very nice explanation. Sir Which device do you use for writing on the screen?

[@shdkdell]

Thanks brother.

[@anamikamaheshwari]

Sir why we take opposite terminal of battery as compare to simple diode ?

[@sandeeptiwari3655]

Please explain me how you made the barrier potential symbol.....I mean p side of diode having -ve sign and n side of diode having + ve sign..... You make this opposite.... Please clear my doubt🙏

[@hm2715]

In reverse bias,,,, diode mostly act as OPEN CIRCUIT,,,, so we take the direction of VOLTAGE

[@parthmodi5734]

Anybody please help. Is this series sufficient for gate preparation?

[@vikku_19]

no,you will have to do more practice.

[@aneshnagle161]

nice way to explain..thanks !

[@sandeep5643]

what is Zener potential

[@bubunmazumder]

Why is the depletion region is smaller than the normal diode?

[@Prashantsingh896]

I have the same question. Since zener diode is highly doped, so the number of electrons in n-region and holes in the p-region will be higher than normal diodes, higher charge carriers means higher concentration gradient among both sides so more number of electrons should flow from n to p side and more number of holes from p to n side, so the region of uncovered ions should increase and hence the depletion region. But this does not happens, I don't understand why ?

[@ayushchoubey635]

Thanks a lot sir

[@samart3010]

Plz upload the video about tunnel diode

[@bestakujwalire4055]

Can you please prepare well organized electronics practical videos as well? Good job...

Both

[@auroshisray9140]

Thank you ..the best

[@Srishi156]

- A zener diode exhibit a constant voltage of 5.6 v for current greater than five time the knee currwnt where knee current is 1 mA . The zener is to be used in the design of a shunt regulation fed from 15 v supply The load current varies ovee the range of 0 mA to 15 mA . Find tge suitable value for the redistor R What is the maximum power dessipation. some one pls explain how to find the power
