I read zener diode regulator many times from books but didnt get how it works still I got marks.. Now m thinking marks can't decide knowledge after this watching this video...thank you so much sir.. You are giving new life to student in field of physics! 🙏
I am serving in Indian navy and I am from electrical branch... After 1 month a promotion test will be held, and most of the syllabus is electrical physics. I went through book but I was unable to understand zener diode. But thank u sir for your hard work, it makes very easy for me to understand zener diode ane how it can be used. Thank u again sir🥰, lots of love from Defence
Physics ko toh bekar me badnam hai,Agar acche teacher se paradho toh you will find it very easy, thank you sir,😊 12th ka course khatam hone ke baadh se eak playlist QUANTUM MECHANICS ka Sir..
Sir if 3V is required in output but instantaneous 1V input is coming , then it will give output as 1V. I mean zener is helping only in removing excess voltage at the load but not increasing it when it is less than required? I mean it's not regulating the voltage but only decreasing the excess voltage according to your explanation.

Sir i am from tripura..i am studying in bsc physics honours..your video is most useful for students..your voice is amazing that means your voice is very clear..sir i want some video about astrophysics..and some videos about some topic of bsc level..i am not satisfied with video of another channels
Sir,zener diode cannot regulate the voltage through the led since it is in parallel.So,here what is its role ?resistor plays the major role.Please reply sir 🙏
I had an exam the day before yesterday n this question came.. But I learned this diagram in a different book n also saw your video. But I could not remember the diagram that I had learned in the exam and I remembered the diagram that I saw in your video. thank you sir for the great explanation that's why I remember everything.😭🙏
Sir, I love your channel❤ and teaching❤❤❤❤ Because you explain difficult topics like fairy tales, we don't feel pressure like JEE NEET in your teaching.
हम सभी के सम्मानिया और मनपसंद भौतिक शास्त्र के शिक्षक आप के पढ़ाने का तरीक़ा बहुत अच्छा है और जो भी उदहारण लेते है वो बहुत मजेदार होता है जिससे आसानी से समझ में आ जाता है। आपका बहुत बहुत धन्यवाद ।आप सभी मित्र यदि इस बात से सहमत है तो लाइक और कमेंट करे।
Sir, when we already know that at what voltage (3) bulb glows and dc source produces 1-6 range voltage.. we can adjust a resistor according to it .. what's the use of zener diodes
Resistors cause a voltage drop, but this drop is not fixed and depends on the current, so they cannot stabilize voltage. Zener diodes, on the other hand, regulate voltage by clamping the voltage at a specific value (the Zener voltage), ensuring consistent voltage despite variations in input voltage or current.
Sir,i think you are the best teacher of physics.your videos very very helpful for me of semiconductor.you really make understand me the mechanism of semiconductor.very very thanks sir.
Sir aapne case 2 m btaya ki input dc voltage 6 ho to resistance 3 volt drop kr dega or output 3 volt hogi Fir ye bataiye ki zener ka kya roll rah gya vaha pr fir to humko uski jarurat he nhi h Keval resistance se he hamara kaam chal raha h
sir, isn't it mean that zener diode 6v ke current aane par damage ho gaya that's why it does not offer any resistance after getting damaged hence most of the current flows via damaged zener diode
Sir I have a Question pls if its possible reply its soon .....Now Q is that agr case 2. Agr voltage drop resistance mn hoga ie 3 volt mtlb bacha 3 volt so it will obviously drop in LED nd it will glow then what is need of Zener here ....??Hope u will reply it Soon..😊😊😊
सर आपने बहोत मस्त तरीके से समझाया और समझ भी आया लेकिन मेरा एक सवाल है जैसे के हम resistor लगा रहे है ताकि वोल्टेज drop हो तो क्या resister भी ज्यादा ओह्म का लगाना पड़ेगा ?
Sir can you please tell if it is the Resistance or the Zener diode that saves the LED bulb from damage? Because you said that if the Voltage exceeds 3V, it will destroy the LED bulb. But, the Zener diode only controls the flow of current, NOT the Voltage. So can you please explain me this phenomenon once again?
When source gives less than 3V I.e. in case 1 then due to resistance drop will be there . Then how the bulb will glow ? And what would be the magnitude of the resistance?
In case of 3v no resistance will be offered and the led will glow but most probably led will fused zener diode helps in regulating the voltage or u can also understand it as a special type resistor which converts voltage according to the required voltage of the led
It was only for visualization , practically your tv , frigde cannot operate within 220V (approx ) like they operate at nearly 200V thus the output cannot fluctuate that much like u vo get 180V in your home and that's how it regulates...
@@Knowledge_n_factz may be the resistance value is very small..and also the current value is small....but in the second case the current value is very large so as to have a large potional drop🙄
Sir but jab hamara resistor drop kr dega 6 se 3 volt to hame zener diode ki jarurat hi kya hai...?? OR Why do we need to apply zener diode if our resistor can drop voltage too 3v ???
If 1v Supplies to 3v zener parallel with diode 3v LED, can't able to operate, zener can't boost voltage, From 1v supply total current flowing through only ( resistance and LED ) Right.
sir why are u not considering the amperage as more current through a led can blow it off.. secondly if reverse breakdown voltage is reached means a more amount of current will flow through zener diode and less current through led will that small current through led will be able to light it up
sir case 1 me 1v h or case 2 me 6v h led 3v ki h aapne fixed resistor lagaya voltage drop hoga kyoki series me h case 2 is ok but case 1 me voltage kese increase hoga 3v tak
He knows physics concepts you can rely on him... He doesnt share bookish knowledge in a bookish way... Thankyou very much sir...
true ....
Yaaa
I would say best on RUclips
Diode reverse biased me kyu lgaya h?

Wha bhai kya example deya 🤟
Its resistor who is dropping voltage not zener diode

I never really liked story telling examples as a method of teaching but man this video was incredible really helped me a lot.
Sir I have become fan of your explanation.. Thank you
Thanks sir ,i m now 11 class but this video is really beneficial.Thanks again sir , you are best faculty of physics
Sir, accept my Pranam. You are my Guru. Truly every lecture is excellent
sir you have given such a good example that it is very difficult to forget the concept...
Teacher ho to aapke jaisa jisko concept actual mein samgh aata ho... Aur bahut ache se samjha sake😃
he does show bookish knowldge but in his own way
excelllent way of teaching .....

I think LED will off now for this state
I had similar doubt
The ans is "NO".
I have same doubt
No ...this led is working upto 3v..not only on 3v
SIR 11:40 KO AAP BOLTE HAIN KI RERSISTANCE KE KARAN VOLTAGE DROP PARALLEL PAR 3V HI RAHEGA TOH PHIR HAMME ZENER DIODE KI ZARURAT HI KYON HAM SIRF RESISTANCE CHANGE KAR DETE HAIN TAKI LED JALTA RAHE AND AGAR ACROSS LED 3V RAHEGA TOH HUM VO DIODE REMOVE KAR DETE HAIN KYON CIRCUIT KO COMPLEX BANA RAHE HAIN
Zener doid regulates current (i) and to suply only 3v we can only
adjust current bcz resistance remains constant
Mera bhi same doubt h
Sir this is the best vedio on youtube on zener diode

agr resistor ne hi voltage drop krna hai to hm zeener diode q lagatay hain?
kia zeener diode sirf current ko control krnay k lea lagaya gia hai
nice question???
Sahi farmaye ho
Mujhe bhi yahi doubt hai
Same mghe doubt h
Are yar mujhe bhi
best explanation ,, very helpful ,,, thanks ........
Sir, very nice explanation
Sir aapne case 2 m btaya ki input dc voltage 6 ho to resistance 3 volt drop kr dega or output 3 volt hogi
Fir ye bataiye ki zener ka kya roll rah gya vaha pr fir to humko uski jarurat he nhi h
Keval resistance se he hamara kaam chal raha h
Aap ko padhane ka tarika gajab hai ek hi bar men samajh aa jata hai you are great sir
If output volate is 1 volt, will not the resistant in external circuit work then?

सर आपने बहोत मस्त तरीके से समझाया और समझ भी आया लेकिन मेरा एक सवाल है जैसे के हम resistor लगा रहे है ताकि वोल्टेज drop हो तो क्या resister भी ज्यादा ओह्म का लगाना पड़ेगा ?
Sir can you please tell if it is the Resistance or the Zener diode that saves the LED bulb from damage?
Because you said that if the Voltage exceeds 3V, it will destroy the LED bulb. But, the Zener diode only controls the flow of current, NOT the Voltage.

same thing is in my mind .... for first case why there's not any potential drop?
@@Knowledge_n_factz may be the resistance value is very small..and also the current value is small....but in the second case the current value is very large so as to have a large potional drop🙄
By using resistor only, can't we control the voltage..as their will be a volatge drop across resistor
Sir but jab hamara resistor drop kr dega 6 se 3 volt to hame zener diode ki jarurat hi kya hai...??
OR
Why do we need to apply zener diode if our resistor can drop voltage too 3v ???
Thank You So Much Sir, Very Beautifully and Greatly Explained Sir. ❤
a lots of confusion and conceptual calarity comes after watching your videos and my brain finally have some peace .... thanku sir
If 1v Supplies to 3v zener parallel with diode 3v LED, can't able to operate, zener can't boost voltage, From 1v supply total current flowing through only ( resistance and LED ) Right.
Great sir.. you explain very well
Sir 40watt ka load h 12v h kabhi v12 se jyada ho jati h to 12 v ke liye kis code ka zener diod lagaye
Teacher should like you❤️❤️❤️❤️
He is just genius at his consept
If the zener reaches its breakdown voltage then maximum current flows through zener diode then how LED goes turn on?
Thank you so much sir.. for the clarity of concepts this channel gives, it is extremely underrated.. it should have atleast 5M subs if not more
Really the example made the concept quite easy...and in whole lecture it was the main thing to focus..
Mind blowing explaination sir
the best thing about your videos is that you give deep knowledge in short time....to the point explaination....thank you sir..
Fantastic 👌.... thanks for the valuable information
great video as always sir..helped so much
Its ac to kvl total input voltage equal total output so 3 volt drop in resistance nd remaining 3 will be in led...
*Sir jb resistor hi extra voltage ko rok leta hai to diode ki kya jaroort hai fir ??*
Same question
Sir you are Sachin of physics
Sir what will happen when led has limit of 2v and zinar diode has zinar volt is 3v then what happened. Please reply sir
Have Zener diode a fixed it's voltage?is set up by our requirements?
sir why are u not considering the amperage as more current through a led can blow it off.. secondly if reverse breakdown voltage is reached means a more amount of current will flow through zener diode and less current through led will that small current through led will be able to light it up
sir Mujhe ek doubt hai
if huge current flows from the zenner diode then what happens to the energy (potential drop)?
Yahi janne mai bhi aaya tha aur sath me ye pata karne ki zener diode kab fail hoga
Kiya without lod led k out put voltage in put voltage hee show kare gaa
You are the best sir ❤
Best explanation
sir case 1 me 1v h or case 2 me 6v h led 3v ki h aapne fixed resistor lagaya voltage drop hoga kyoki series me h case 2 is ok but case 1 me voltage kese increase hoga 3v tak
