bemisaal sir aajtak aap jaisa consept koi de nahi paya kameene log ek ek ghante ka lecture lekar aa jaate hain lekin consept de hi nahi paate hain lekin you gave supersmart consept thanks sie r
1st one is not a proper question... When a normal pn diode can control the reverse saturation current without causing damage(because of heat) in reverse bias then its called zener diode.... Because this functionality of diode can b usefull just in the case when it can handle reverse saturation current which flows because of reverse bias... 2nd answer: Depletion layer depends on the impurity density...when its high the layer will b thin if its low then the layer will b thick.... When the layer is thick then the breakdown voltage is of that diode is called Avalanche breakdown on the other hand when layer is narrow its called zener breakdown... The width of layer is taken narrow for zenner diodes this is for eliminating the collusion as in normal pn diode which generates a lot of heat...
Plz answer my doubt. We have a fixed resistor ( Rs) so how will the current drop vary? Sbse pehle supply resistor se hokr guzarti h toh uska drop toh constant hona chahiye na ye kaise aur kyu badalta hai.
sir u used this formula for increased voltage then it will keep the voltage constant ir 10V but if voltage comes down then due to potential drop it will come down than 10V.Then how can it b explained?
the input must be more, then only you will get constant output. if input is less the you won't get constant output. generally the fluctuation are less, so input voltage won't be that much less.
Electrical Technology sir zener diode is used in case of fluctuating signals...if it can increase(you explained it) then fluctuation may also lead to less input than 10 V.plz explain
impurity badhane se depletion region kam(decrease) ho jata h...........(less impurity , more depletion region), (more impurity , less depletion region)
its about balancing the drift current and diffusion current. If you have very low doping, a large volume of depleted semiconductor is needed to generate enough electric field to balance the diffusion current. On the other hand, if you have very high doping a much smaller region is required to balance the diffusion of carriers.
Due to heavily doping on both sides and this results in increase of electric field and thus the immobile charge carrier gets drifted and depletion region gets thin
You are decreasing voltage in the negative and somehow the depletion layer is getting less? How did the zener diode break down you did not explain just told us because of Zener voltage being equal to minus voltage! Disappointed

Mistake in this video is from 4:25 minute i.e. electon will move from N to P.
Now see NCERT page no. 485 zener diode 3rd paragraph 2nd line.
You are right 😱😱😱😱😱😱😱😱😱
Symbol is also wrong
Sockty diode symbol make
That's what he said. Electrons will move from N to P
very good sir you have made physics so easy for us thank you so much
Hy
thank u so much sir....aapne hr ak vedio hmara besic concept clear ho rha....thanks alot sir....
Very very thnx sir aap bhot km time mein bhot acha pdate hai

Sar thank you your concept is very easy and useful
Sir your videos are very very helpful for us please please sir keep uploading these kinds of more videos ..we wil be very thankful to you🙏🙏🙏🙏
Sir little bit confusion in circuit, if zener is breaking down at higher voltage then how it is regulating voltage , was IRs not previously there
now I have no doubt related to this topic . thanks you very much sir.
1.Why zener diode is connected in reverse bias? Explain.
2.why deplection layer is narrow?explain.
Good
For flow of current in reverse bias .. A special type of diode is used is called zener diode
1st one is not a proper question...
When a normal pn diode can control the reverse saturation current without causing damage(because of heat) in reverse bias then its called zener diode....
Because this functionality of diode can b usefull just in the case when it can handle reverse saturation current which flows because of reverse bias...
2nd answer:

The width of layer is taken narrow for zenner diodes this is for eliminating the collusion as in normal pn diode which generates a lot of heat...
2. because of high doping of impurities in both p &n semiconducotor.
Plz answer my doubt.

bhaii depletion region bhi increase hota ha tabhi electric field increase hoti ha....Tmna kha depletion region kaam hota ha...???
Best video of zener diode on TH-cam. I got everything by watching the video. Keep going like this sir 😄😃😊
sir please feedback amplifier, Hartley oscillator, linear multimeter ka video send kr dijiye
Very well explained. Thank you 😊
sir agar low voltage aaye gi to kya hoga voltage drop nahi hoga ya phir zener ka volage bhi add ho jaye ga
Sir isko kiya ac or dc me two jagay use hota he ? Na sirip dc me use hota he.

impurity badhane se depletion layer mein kya changes aate hai? plz answer
impurity badhane se depletion region kam(decrease) ho jata h...........(less impurity , more depletion region), (more impurity , less depletion region)
Electrical Technology reason behind this?
its about balancing the drift current and diffusion current. If you have very low doping, a large volume of depleted semiconductor is needed to generate enough electric field to balance the diffusion current. On the other hand, if you have very high doping a much smaller region is required to balance the diffusion of carriers.

Depletion width kyoun Kam ho jata he with dipping
How the depletion gets thin if the diode is reverse biased
Due to heavily doping on both sides and this results in increase of electric field and thus the immobile charge carrier gets drifted and depletion region gets thin
Thanks sir
