Transformers - working & applications (step up and step down) | A.C. | Physics | Khan Academy

- Transformers step up (increase) or step down (decrease) AC voltage using the principle of electromagnetic induction - mutual induction. A changing current in the primary coil induces an e.m.f in the secondary. Since the e.m.f generated depends on the number of turns, the voltage induced in the secondary can be changed - stepped up or down - by altering the turn's ratio.

One thing I have noticed....all the Khan academy teachers have that positive vibes emanating.
Because all khan's are super cool 😂🦋
@@romarani9525 yupppp agreeddddd
😭 yes and those positive vibes ~~ are contagious which end up helping out a lot of stressed idiots like tone the panic down before an exam 😭🙇♀️🙇♀️🙇♀️🙇♀️🙇♀️
Like me *
I want to like but that 111 looks so nice there
They are gods living on Earth. In the era of business education, that are providing free of cost education. Thank you Sal Khan and Khan Academy and all its Teachers for existing!
Babe ! Why don't you mention too early 🤷!?
TH-cam Jo pesse deta ha unko
You have managed to teach me in 10min something that my school instructor did in 4 hours and still don’t get it. So thank you for all these great video sharing your knowledges and skills to the world. Keep it up!
True.
Thank you sir.... superb work for MdCAT students 🤗
I sweeaarrr
Seriously, no words to describe. Animation and explaination both were awesome. I haven't just think about wireless charging is done by this method. ........ Unbeatable 🔥🔥🔥🔥
Hands down, the best video on transformer. I ever watched!! Thank you sir for being such a great teacher!!
mind-blowing explanation .....Im engineering student , and if I stuck anywhere ....my mind says like ....khan academy hain na 5min me concept crystal clear hojayenge.
Outstanding teaching that touches the micro to macro level 👏👏👏
Bro honestly, khan Academy India has saved my butt a thousand times from all the confusing lessons I learn at school! Thank you very much!!
I barely comment on TH-cam but the Khan Academy has such consistently excellent teaching, I thought it deserves a mention.
I love that how he explains everything practically and it makes so much more sense which makes it easy to understand❤
the best thing about this educator is how he bulids things up slowly amnd genuienly taeches us the importance of every component
I can't thank you enough for all the effort you have put into these videos
U know its gonna be an wonderful session when u hear MAHESH SHENOY'S voice.
This is literally the best lecture on tranformers, great explanantion all doubts cleared. Most of the other videos I found were mostly just definition and formula based due to which I couldn't actually get their working.
We've all been using wireless charging all this time 🤯
You owe the prize of my best teacher. Sir,You explain really well .Love from india.keep going💐
Such a useful video. Thank you khan academy for make things easy and clear for us. Thanks a lot💙.
The enthusiasm in his voice when explaining.... is what keeps my hope in people
your teaching is beyond words to express....
Very well explained, better than my teachers!
Excellent teaching👌our teacher shows your videos for all lessons...
Loved it, so beautifully explained ❤️
it's an excellent platform for science students to evaluate physics in a beautiful and exciting way.
Thanks, khan academy
Hats off to u!!
I am from Egypt. How can I find questions or exams on Google about Kirchhoff and Ohm's law for closed circuits?

Mahesh Shenoy sir is best teacher on khan academy for both English and Hindi lecture ❤️ thanks sir for creating such valuable videos
I just learnt so much! This content is helpful
Thanks!!great explanation!🙌🏼✨
i like how they are actually excited about what they are teaching makes u want to pay attention :)
Great video. Coming from someone like me, who knows zip about electronics, that's a HUGE compliment.
Finally an Indian with good accent
I never thought that physics was interesting until i started watching your video's ❤❤❤😫😫😫😫
Well explained sir, I'm satisfied with your teaching👍🏻❤
Everything is here I wanted to know
You are better than those (professors) in college
THE BEST!!! BEST!!! BEST!!!! BEST!!!!!!! BEST!!! I SWEAR TO GOD!
Loved the video, thank you Khan academy!
Very nice explanation ... loved it❤
I love how he speaks!
Thank you very much Sir, hope we'll learn many more from you
You are simply great...😍😍😍😍
Super helpful!
Mahesh sir is my favourite teacher.....
I dont even know a word in this topic befor and now i am so advanced ,i don't have words,i was watching the video and thanking at the same time
I understand all.Thank you.
Great explanation thanks 🤗🤗🤗👍👍
OMG, the explanation is top notch!
10X better tutorials than 'Physics walla' or 'vedantu' who only do brand promotion and timepass. Clean and to the point. Thank you!
Rightly said pw is brainwashing students in mass with thier half cooked content
Thnx for this
Amazing explanation
Khatarnak explanation 🔥
Thank you so much for such a detailed explanation sir
At my last minute it is really time saving and is very helpful ❤️
Thanks a tonn 🙏🙏🙏
First Like.
great!
Very good explanation.
I appreciate your existence
This tutor is superb. I wish I can get the opportunity to leave my country and migrate over to where you are and continue to receive intense training in physics and engineering as an undergraduate of Mechanical Engineering that I am.
Well thats the benefit of online education, isn't it?
Anyone from anywhere can learn what they want
Thank you for providing us education .
May god fulfill your wishes and keep you healthy and may you live a long and happy life.

Ikr😂😂
Mash allah 🎉You teach very good 👍
Great teacher hats off
thankyoou so much it was so useful for my class \
Great job👍
Very good explanation
❤From srilanka 🇱🇰 ,thnk u ❤
He never ask for subscribe. I like this 👌.
tysm amazing explanation
More than meets the eye indeed
I have a doubt
If the change of magnetic flux generated can produce the same amount of emf in another coil(secondary)
Then wont the change of magnetic flux induce the emf in itself(primary coil) and affect the flow of current in it?
A very good video...
hats off physics dhoni
I owe you everything my guy
great tutorial
This video was far more entertaining than the actually educating
oh, amazing explanation
Thank you so much .
Sir but current increases on decreasing the voltage
That means microwave needed less current than charging mobile
Thanks sir 👌
accidentally this youtube channel is underrated
Within one year or two khan academy in India is gonna grow some 10 to 20 times.
If our school college & university education become like Khan Academy teaching, we are will become 👨🔬scientist's
Study English grammar kid
