Nikhil Rao in this video sir gave us a example in which sir varied current according as emf to get a constant voltage in output. My confusion is that does actually current varies in the real circuit according as emf to give constant voltage? Physics doesn't depend on our calculation but our calculation must satisfy physics. Please solve my confusion
@Subham Jena, in normal circuits, as the voltage rises, the current rises PROPORTIONATELY( as they follow ohm's law ), but in semiconductors like zener diode as the volatage rises( beyond a particular value i.e., breakdown voltage ), the current rises EXPONENTIALLY nd thus voltage also drops to a much higher extent. Hope ur doubt is clear brother.
Vaibhav Gupta i understood but i have a doubt. What is the value of the resistance which drops potential? Is there any specific value or arbitrary value ?
Tutorials point you people are really doing a great job providing quality knowledge in this RUclips platform. So grateful to you. Sir your explanation is simply superb. Thanks a lot for this amazing lecture !
@@bionicpenguin5471 at first some one from the comment section told me that he passed away ...I asked the same to him ...he told me yes..i didn't believe him and in another video another guy replied to sum 1 that he passed ..I think it's true
sir i was not able to understand zener diode whole year but when i saw your video , it cleared all my doubts ........THANK YOU SO MUCH!!! YOU ARE THE BEST
Awesome teaching and got the concept at ease.. Will be useful if do more RUclips lectures.. Best and patient lecture I've ever seen in RUclips so far..
Thanks a lot sir you are really a genius physics teacher in our country and in my I think you are genius physics teacher in the world your explanation are just same as explanation of Richard Feynman's explanation. Sir you are genius really
Watch this video at 1.5X or 1.75X it helps save some time. But sir your explaination is fabulous understood all the topics for which i referred your videos.
Due to the heating effect large no.of covalent bond get broken and large current flow through the circuit nd causes a breakdown called avalanche breakdown
Sir i have a question If the voltage exceeds breakdown voltage then the zener diode will not offer any resistance and will simply start acting as a wire so why the current will flow through the resistor when it has a simple wire to pass through ?
JAAT if you really want to understand this thing....then read my note patiently.....the concentration of zener diode is very high.....and it operates in breakdown region......you ask if there will breakdown and current leads high then why go to resistor???....my brother we regulate the voltage not temperature......and after breakdown occurring in zener diode....it will act like a constant voltage source......by constant potential difference....we find a current in our circuit....and remember..... although breakdown will occur but it doesn't mean..it is a wire...it regulates the voltage at a constant value.....I hope you got some idea.....if yes ....then please send me ur feedback😇😇😇😇....keep learning
While watching this video I have only one question hovering in my mind is that why tihe voltage accross zener diode is constant??(don't say according to vi characteristics)
Actually the input Voltage must be greater than the zener voltage for the proper regulation.. i don't think it can increase the output voltage... I may be wrong as well... If you find it, please answer me 😊😊
If the input Voltage is lesser than the zener voltage, no current can pass through it.. as current only flows when the voltage of input exceed the reverse breakdown Voltage
Nicely explained. What will happen if the input voltage is less than Zener voltage? will it regulate it to Zener voltage or allow it to pass through as it is?

Best video on this topic on RUclips so far hats off to Pradeep sir god bless you may you live long
👍👍👍👍thank you sir
When input is leess then break voltage

This is such a great explanation. These lecture series must be recommended to all the higher secondary students.
Tutorials point you people are really doing a great job providing quality knowledge in this RUclips platform. So grateful to you.
Sir your explanation is simply superb. Thanks a lot for this amazing lecture !
Just excellent,,best video I had watched on zener diode as voltage regulator 💯💯
Your nailed it Sir
Thanks thanks thanks thanks thanks thanks............upto tan90
Sir , you made physics very easy . May u live long😘
Oh girl
Bulati he magar janeka...nhi...
Sir passed away😥😭😭😭😭😔
@@rathaprasi6135 is this kinda joke??

my best electronics lecturer on you tube.old way of presenting but very very effective.keep it up Sir Pradeep!
I am really amazed by ur teaching Sir, thank you🙏
PERFECT! Wow I love it when I find someone that teaches so good and saves me from losing so much time.
Never seen a techer like him
Sir, your way of teaching is so easy to understand, thanks sir, for making video on topics and providing us
i always watch his lectures ....damn amaxing.......
boom sir i got this in just 2 min. your example of pressure was awesome. thanks for this helpful video..
It was.....Outstanding sir👍👌 great job.....Keep up ...Good. work......
Best explanation of zener diode.
♥️♥️
Fantastic my dear nice explanation your de best teacher
We need lectures like u sir

amazing class.
thank you sir finally understood
so thanking you sir...for such an understandable class.
I watched ur every video at 1.5x speed
Same dud
Me at 2.0x and i feel it,s the real voice
Mee too
Thank u for ur precious lecture sir
Why does not zener diode work in forward bias sir?
Bro,what is breakdown voltage? Plzz say bro
Bro, breakdown Voltage is the voltage at which maximum current flow through the circuit.
@@RashidKhan-qf6pu what is avalanche breakdown voltage??
Avalanche breakdown is the breakdown which is caused due to thermal effect.
Due to the heating effect large no.of covalent bond get broken and large current flow through the circuit nd causes a breakdown called avalanche breakdown
Thank you sir
Thank u sir💐
Thank u for ur precious lecture sii
you got my problem
Sir i have a question
If the voltage exceeds breakdown voltage then the zener diode will not offer any resistance and will simply start acting as a wire so why the current will flow through the resistor when it has a simple wire to pass through ?
No Bro, Zener diode will resist the flow of current due to junction field
JAAT if you really want to understand this thing....then read my note patiently.....the concentration of zener diode is very high.....and it operates in breakdown region......you ask if there will breakdown and current leads high then why go to resistor???....my brother we regulate the voltage not temperature......and after breakdown occurring in zener diode....it will act like a constant voltage source......by constant potential difference....we find a current in our circuit....and remember..... although breakdown will occur but it doesn't mean..it is a wire...it regulates the voltage at a constant value.....I hope you got some idea.....if yes ....then please send me ur feedback😇😇😇😇....keep learning
Temperature no...that is current....so sorry
Tnx so much sir. Content well explained
What happens when the given voltage is less than the zener voltage?
No current will flow through Zener allowing the voltage across load to remain the same.
Sir if I use zener in forward.will the voltage constant??
I don't understand why the voltage across the zener diode gradually decrese?
How does it work for less than 10
Sir thank u so so much u are awesome
Salute sir...
While watching this video I have only one question hovering in my mind is that why tihe voltage accross zener diode is constant??(don't say according to vi characteristics)
Example level 👌water tank
Sir what happens when input voltage is less then zenar voltage.... how it reaches to zenar voltage.,..??
rakshith s gowda it will reach to Zener voltage by increasing the voltage
Actually the input Voltage must be greater than the zener voltage for the proper regulation.. i don't think it can increase the output voltage...
I may be wrong as well... If you find it, please answer me 😊😊
If the input Voltage is lesser than the zener voltage, no current can pass through it.. as current only flows when the voltage of input exceed the reverse breakdown Voltage
Thanks sir
Thnkuuuu sir
Sir example 👌
Nicely explained. What will happen if the input voltage is less than Zener voltage? will it regulate it to Zener voltage or allow it to pass through as it is?
Then current flow through diode is negligiblebelow the breakdown voltage
Sir wide pipe Lo water Lo takuva unapudu small pipe Lo ekuvaga veltae kada
Thanks a lot sir
Sir agar voltage 80 se kum kr de toh kya hoga???
Can u expalin properly aout avalanche breakdown and zener breakdown plz 🙏🙏🙏🙏
