- Half wave rectifiers convert A.C. to D.C. by conducting for only half an input cycle. Let's learn how we can use a PN junction diode to build a simple half-wave rectifier circuit. In the next video we will build up on this to learn the full wave rectifier circuit using 2 diodes.

Class 12 Semiconductors: We cannot imagine our life without computers today. But what makes a computer tick? What's making this technology grow at such an exponential rate? It's all due to semiconductors. As unbelievable as that might sound, altering the properties of semiconductors allows us to build these computers. In this topic, we will explore the world of semiconductors. It's a journey from what semiconductors are all the way to creating building blocks of these computers.

Wow! Best efforts given. Explains what none of the books can.
Trueee
Yes
100%true
With JEE Mains just almost 2 months away I was panicking. But as I am understanding these concepts I realise the very reason I loved Physics back in class 10. The fact that learning is actually pure joy... but the current scenario that makes us only think about writing the formula and getting the marks is just crushing the curiosity
Paper kaisa hua jee ka
I relate to this on a whole diff lvl!
Man you brought a tear to my eye
I need this type of teacher in my school😭😭
🙂💯💯💯
100true i miss gd teaching only blind memory my book
Then on the last day the teacher will say OK CHAPTER 4,5,6,7,8,9,10 read by you self 😁😁
i love the way khan academy explains stuff with a pinch of humour🤣
I go for school & two extra tuitions for physics but unfortunately I couldn't understand these concepts anywhere.
I'm really grateful , thankful , & appreciable for your academy to help children like us for free.....
I promise i'll donate my first earning to this academy volunteerly
Truly! indeed they do it as non profit. And for that reason we are always blessed. Good motive.
Really an under-rated organization. Whatever our NCERT books failed to teach us, Khan Academy taught us the same thing in some videos!
real
Finally a channel that explains in english, and that too with such simplicity and great demonstration. Thank you so much sir😁
This took me nearly 3 years to get my head around in university...and I finally understand it after watching a ten minute video. Thank you for making this so much simpler and understandable than my lecturers ever did.
My teacher made this topic so complicated but everyone was getting it, I thought something is wrong with me but turns out the problem is not with me as I understood this topic by watching this video!
Same bro
Lol. I tried to understand this chapter on the unacedemy JEE you tube channel and that shithead didn't do anything except drinking water.
Thank you this was just sooooo helpful
For real I trusted that channel blindly and when I couldn't understand I thought it was just because of my dumbness. Really regret it. And the funny part is that they take 1 hour teaching a certain topic and half of the time they're bragging about how great their channel is and here in only 10 minutes the concept is clear. No hate because well they're teaching for free so ofcourse I have no right to say anything against them but still I wasted a lot of my time and not all of the teachers there are careless some teach really well.
i could'nt understand a single word of physics from my ncert textbooks and this subject was really becoming a bother for me. Khan Academy u explained what my teachers and textbooks couldn't make me understand. i can really for the first time relate all these concepts to real life practical situations. Thanks a million for making me learn, understand and love this subject. All the kids who don't know about khan academy are missing out on something incredible, and i hope that many more of us come here to study this subject. Hats off to you Sir!
👏👏Understood. No book can explain like this.
Why did it take me so long to find this channel 😭
But glad I found it 💟 thank you so much 😭 I really appreciate it
Dear Khan Academy, you made a kid not only learn but love physics😊
omg...how can someone explain in such a way 5 yrs before ....hats off to u sir ...helped a lot..have my boards tmmrw
I'm so glad I found this channel 🔥
I love those bonus words 😂
Please, make some more videos of electronic problems, it really helps me
I don't know why this Intuitive amazing vedio is underated, People surely don't have taste these days. Anyway love from Bangladesh 💗💗.
How can you teach so efficiently?
I got the whole topic stuck in my mind in just 10 minutes. You are simply amazing!! Hats off!!
I opened my charger to see the whole system right after this video. This is called quality education, learn practically. Take love ❤️.
Khan Academy is now in India thanks guys
Sir this is the first time i have truly understood science
Fully satisfied.....
Even after spending lack of money in coachings we can't get the concept.....
Its worth it to watch10 min of video....
You are an excellent teacher Sir!!!!!!!!!!!!!!!
I can't thank you enough for all the effort you put into this.this is just amazing
Guys I bet uh, u won't get a better video than this in the whole of the utube!!
I wasted a lot of time,
searching for videos where I could understand p n junction, rectifier clearly...
And then I found these videos where I understood it finally!!!
Tqsm🙏🏻🙏🏻👏🏻👌🏻🥳🥳
THIS is the best video I’ve seen on PN junction diode working as a rectifier. Thanks a lot sir for clearing our concepts!!
🔥🔥 Thank u sooooo much...This is what I was searching for. This made my concepts crystal clear. 🇧🇩
Amazing amazing i have fallen in love with semiconductors
Best explained sir thanku so much
The funny analogy of hiring a person to control the flow of current in only one direction made me understand the role of PN junction diode in this rectifier really well! 🔥 Thank you so much for this video!
When I finally understood this, I started weeping 😂
You can really make your students love the subject 😊
Best explanation ever. I was fully confused about this from my diploma class
This is the best explaination! Thank you! You are life saviour💕
Wow sir
You are making physics interesting for us
Thank you so much
Amazing explanation! Thank you so much
At last understood thanks khan academy
I'm afraid this channel will not be existed.... U save my lifeee thank uu sirr
Who are you man ? A magician ? Btw thnku❤
I have my last physics revision exam tomorrow and board exam in a month but only now am I learning that alternating current actually switches its direction of flow. Way to go NCERT and the subsequent schooling system.
You are best in only 10:55 minutes
I already knew this topic, but your explanation is so beautiful that I kept on watching as if I am watching my favorite movie again.
oh didnt expecte such an immense explanation from indians
really grateful for all of the efforts put in to explain these concepts! Made my life 10X simpler
This was really helpful and fun to watch... Physics made fun👍
Super explanation and animation. I think There will be no one who is disliking this video. And sometimes the voice is like men's and sometimes womens
I really love the way how he explains this topic in fabulous way🥺❤️❤️❤️❤️❣️❣️❣️❤️
simplest and the best explanation ever...thanks a lot sir....
I can't stop watching ! Help

Wow you're so enthusiastic in the stuff you're teaching and I understood every single bit! Great job and thank you so much!
wow thanks i understand it very well
this channel deserves more subscribersss😃😃☺☺
from Sri Lanka
Thank you so much i only understand animated videos and this video gona help me so much in my upcoming physics paper...❤😙
amazing!!! loved the explanantion. just realised i found a goldmine
i founded this gold mine from the starting of my 12th standard
I've understood the concept really well. Thank you so much. However, I do have a question. According to the books I'm using, the diode is connected on the other wire, ie. before the load resistance. So in that case, what I don't understand is this: when the diode is reverse biased, wouldn't current pass through the resistor first and then the diode, which will stop it's flow? Wouldn't there be discharging in the load resistance then? Isn't it the same as not using a diode at all then?
When the diode is reverse biased, the circuit is open. Regardless of where the circuit is open the current won't flow.
Imagine a circular road full of cars. If one car is unable to move, none of the cars can. Regardless of where the car is.
Does that make sense? Feel free to ask for more clarity
@@KhanAcademyIndiaEnglish It does make complete sense. I understand it now. Thanks so much!!!!
@@KhanAcademyIndiaEnglish Sir if a circuit doesn't work when a diode is reverse biased , then how did it work in bridge rectifier ? In bridge rectifier circuit , two diodes are reverse biased , so how did the cars move in that circuit then ? Hope you would reply soon
You are great, Serving the Society.❤
Speechless over this explanation
It very helpful. Thank you 🙏
You're literally amazing, thank you.
Powerful explanation !
