No words to THANK U RESPECTED SIR... u hav xplained the concept so deeply...Im so happy ..bcos of u Im in love with physics ❣❣ now its CRYSTAL CLEAR 💯

[@prateekchauhan5959]

Absolute genius piece of work!

[@bheemsinghchauhan9499]

Sir u r my guru.. thank u sir for help students...

[@avinashdubey1806]

Really sir you are god of physics

[@rajeevkumarkushwaha5144]

Nice video for those students who don't go out side of their home town like me ,a lot of thanks sir

[@heartly_doc7550]

Sir u r really so intelligent

[@deepakchandravanshi6274]

sir ...simply you are awesome... i hv never seen someone like you...this topic was always fears me but now it is too much easy for me...thanks alot

[@jagatnarayan2515]

Awesome explanation and thank u so much

[@kalpananigam1116]

Mai class 12 se zener diode padh rahi hu aur iss samay mai electronic science net jrf ki preparation kr rahi hu lekin aj first time mujhe zener diode as voltage regulator smjh aaya Thank you so much sir 🙏🙏

[@vinodSharma-ny5oi]

U r best teacher of physics....... 😆😆😆😆😆😆😆😆😆😆😆😆

[@rashi2937]

Best teacher ever 😊❣

[@pristinpristi9852]

Sir please write it down whatever you explained... I've to prepare notes... please

[@SUNO_VIJAY]

Owsm lectures

[@Rajveerpratapsingh3755]

Sir pls write whatever u explained

[@rupeshkoirala4557]

electric field between depletion layer is maximum then it should also pull the inner electron of depletion layer and p layer

[@NituKumari-ef7cl]

Thank u so much sir 🤗

[@parmatmayadav6834]

nice

[@BTCIVARJUNTAMBHALE]

thank you

[@yashijain4955]

sir plz physics important topic , conceptuals and numericals for 2018 CBSE board bta dijiye

[@jayjakasaniya8572]

sir aap bahut achha padhate ho

[@saqibnazir6286]

😍 u sir

[@akshitathebest1011]

Sir reverse current flows due to which minority charges as concentration of both p type and n type increased so there will be hole current too..so what we consider reverse current is because of electron or hole..?

[@akshitathebest1011]

In diode reverse current is due to which electron or hole as this is pn junction so here is both p type and n type...sir my question is which current is higher in case of reverse bias. ?? Or we should always consider hole current lesser than current due to electron

[@injourney7147]

@@akshitathebest1011 in p- electrons & in n- holes are in minority......so since there is no barrier for those minor electrons to travel to minor holes , neutralise it & create a hole at its place which is again filled by other minor electron......it is maintained by a potential difference in case of reverse biased diode .....although the number of minor electrons and holes does not change and there a const. current which flows ...name given as reverse current because it occurs in case of reverse biased diode. So reverse current is because of both minor particals and its value becomes const. after a application of certain voltage .😀

[@girishshankarrai6488]

sir u ar so good u help students like me lot A LOT OF THANKS TO YOU SIR

[@youtubepolice6085]

Sir camera quality not good I have seen my settings sir

[@nirmalsharma3213]

god level

[@nidhisethi3135]

really helpful sir :) thankuu so much :)

[@kamleshray1090]

Sir special theory of relativity samjhye na aap bahut acha samjhate hai

[@Jaya_Y4dav]

sir...according to reverse biasing... depletion region must be increase..... but at 12:20..u said that it will decrease.. a great confusion sir... plz clear it

[@somratdutta]

same doubt

[@riyajain949]

I too have same doubt

[@sumitpunia9793]

Force of repulsion of electrons + force of repulsion of holes is greater than applied potential... so, result will be in decrease of layer & also explained at 14:50

[@Jaya_Y4dav]

thnks

[@ravidhanju8552]

Yes..

[@e.a.rahman7197]

what is the work of the resistor which has been connected

[@renuchauhan6907]

If supply voltage is less than ,how zener regulate terminal voltage

[@tarunpratapsingh5276]

Sir , we uses the property that a input voltage greater than the zener voltage (set to required voltage) will be drained out by the increased current and the output voltage will be constant, Vi = Vo - Ir can't we use the forward baising so the "cut in" voltage will be set as the required voltage and and any input voltage above that will be drained out as increased current ?

[@kgnstarinterior2118]

sir p to +ve or n -ve hota hai to electric field p to n banni chahiye par ap n mien +ve sign dikha rahe ho or p mein -ve sign dikha rahe aia kyon please reply sir

[@injourney7147]

p or n dono neutral hote hai......jab junction bnta hai tb p k holes ko n k free electron neutral kr dete hai aur apni jagha +ve charge bna dete hai.....vaise hi p k holes ne electron except kiya toh uspr -ve charge aajata hai.....isliye p ko -ve aur n ko +ve show krte hai aur electric field flows from +ve to -ve....😀

[@injourney7147]

p aur n +ve,-ve ni hota....ye bs representation hai......both are neutral

[@krishnachowdhury7601]

you are wrong brother.. actually sir put it by mistake.. n is full of free electron it is negetively charged.. amd p acts like positive

[@siddhantpradhan9354]

If the voltage is fluctuating in the saturation region of reverse biasing,then can zener diode work as a voltage regulator???

[@Er.DeveshKumarGangwar]

sir maine Electronics Engineering ss polytenic diplomaa hu par aaj tak keval paper clear karne ke liye Zenor pdaa tha .. Aaj pahlii baar shi ptaa chalaa ki Zenor diode kyaa hota h

[@maulikdev5040]

E=-dV/dr so the electric field should decrease right??

[@manasvishekhawat725]

-ve sign for direction E is vector quantity

[@mahimamishra8265]

sir hindi ke video lecture nhi upload hoge kya ab.

[@zintapriya1463]

😊👍🎓🎓🙏🙏🙏🙏⏰

[@akarshit8556]

sir agar voltage zener voltage se kam hogi to current ki direction kya hogi...............................

[@raghavsethi8481]

akarshit srivastava then the current is not going to flow..

[@Rajveerpratapsingh3755]

Sir apki bjah s mere physics m 89 marks aye in biharboard

[@shivamprajapati4582]

Sir location

[@trehg3236]

At7:22 how current can be increased after a fixed value,??

[@madhavmadhav3781]

sir ye notes written me net PR nhi hain??? apke

[@mosaic34]

the graph of reverse bias is wrong....voltage stays constant and current increases rapidly....

[@garvanshbhandari9626]

good video but a very long explanation

[@jagritbudhiraja6391]

Sir itne ache se samajh nhi aaya mujhe ye topic
