What are inductors? (self-inductance) | Electromagnetic induction | Khan Academy

[@YogeshSharma-gl8yt]

No teacher explain like you in India they just focus on formulas hats off to you sir

[@hellobro564]

Yes very true they only know how to do problems

[@marq6325]

Why u take off ur hat

[@littlejohny9545]

Harsh truth

[@mitochondria4893]

Your teacher *

[@lekaotamoeta2171]

He's the best!!

[@matibrusco]

I've been in Electronics for 20+ years, and this is by far the best explanation about inductors I've seen, great job !

[@KhanAcademyIndiaEnglish]

[@Tamizharasi1979]

You are something special MR. Mahesh Hats off

[@adammikhail2420]

I love the way you teach, it's like hearing a story😍

[@mery_lv_c]

Indian tutorials are leading in KZbin. I even find tutorials that are rarely made by other nations.👏🏽👏🏽

[@lambda5949]

Ikr, I'm studying Galois theory for my physics program and no matter how niche the topic I'm looking up there's an Indian channel with an explanation, it's amazing

[@DiamondsR4Everrr]

Wow, I read this in the book like ten times over and over trying to fully understand it. I listen to you explain it once and I get fully. Thank you!

[@kripayadav7925]

The reason for why I love physics is because your way of teaching is incredible........you make the topics alive and everything gets crystal clear

[@shide1473]

he is funny 😂 I'm giggling while learning

Hi mister Shenoy! I just want to say that you reaaaaaaaally helpt me a lot! I'm studying Biology at the university in Belgium right now and Physics was always my most difficult subject. BUT NOW I FINALLY GET IT! I love you man, I really do! ❤️

mee too !

[@jimgowtham]

Moral of the story : Final Battle : - Inductance says -- I HATE changes in the current..!!! 😝 Good one sir.

[@Arkad_1]

Deep respect for you. Your explanation was detailed and yes we won't forget that the Inductor has no issues with the current just the change In current

[@warindark]

this gotta be one of the best explanations for the inductions

[@marq6325]

Allow me to ask, why is the current in the circuit changing over time? I thought this is series circuit in which current is constant?

[@mrcastor9514]

@@marq6325 the current wants to go from zero to some max value. In a simple resistor circuit it happens almost instantaneously but when an inductor is introduced it forces the battery to increase the current slowly in some equilibrium condition. Once the current reaches its maximum value then the circuit behaves like a normal resistive circuit except that the inductor stores some energy in magnetic field.

[@xlr8_bs514]

​@@mrcastor9514Is there any explanation for how the inductor is actually forcing the current to change gradually? That's the one concept that I just cannot grasp!

[@mrcastor9514]

@@xlr8_bs514 the Lenz's law. Initially current inside insulator is zero so is the magnetic but when current increases, because of the shape of inductor, the magnetic field increases too. If you want to know a more intuitive answer then sorry bro I don't have it. It's been a more than a year and I've nearly forgot about all of this I studied in School.

[@bharatarora.]

@@mrcastor9514 Field due to a coil or solenoid depends on the current passed through it. Due to self inductance back emf is induced . To pass current through a inductor work must be done against back emf

[@vivekgupta3692]

*_Summary Of The Video :-_* *Inductors and Self Inductance* * When we connect a bulb to an inductive circuit using a DC supply , we notice that bulb takes some time to glow in its maximum brightness. * Inductors do not have any problem with current. Inductors have problem with *_change in current_.* * Whenever there is change in current across an inductor , it induces an *EMF* to oppose that change in current. * The ability of an Inductor to oppose the changing current by inducing an EMF is often called *INDUCTANCE* (Self Inductance) * If changing current and opposition both are happening in the same coil then it is called *SELF INDUCTANCE* * Inductance is like *Inertia* . * Unit Of Inductance - *Henry* * When we turn off the switch we see a *Spark* because of incredibly high voltage supplied by inductor due to decreasing current. * It is dangerous to turn off switch of an inductive circuit because we might get a heavy shock.

[@anjanakumari6008]

Thx i wrote these in my notes i was confused as i have less time to make notes ❤

[@nesma8006]

This sir, is what we call "perfection" Thanks a lot.. I was starting to get hopeless and then, thanks God, I found this video :)

[@thisguyispeculiar]

Super useful. Couldn't understand what on earth an inductor was and we have already gone past AC circuits and LCR combinations. But now it all makes much more sense.

[@rktiwa]

It is the voice, affected accent and drama that kill it especially after you heard Salman's rich, smooth and resonating voice.

[@olli9618]

Wow. It’s been a long time since I’ve seen an educational video done so damn well. Huuuuge thanks.

[@satishvishwakarma9177]

Incredible sir !! It was a great experience to attend your lecture.

[@kags8160]

i always find it fun, when teachers explain pure science by saying "the coil hates the change in current" or f.ex. "the electrons WANT to have 8 electrons on the outer shell". ofc its easier to understand it like that but for people who are driven by pure facts and rationality its controversive when they explain it like that and its fun

[@jocelyn5336]

I'm very very grateful for this video. Thank you so much. Pls continue to teach like this and help students love physics. Lots of love from Oman. ♥️🙏

[@michaelconfidence5563]

God bless you so much, the best way to learning is by using stories, you’re a great teacher. Thank you sir😊

[@m_ali4476]

im suprised that your topic are same as topics taught in my country

[@abhaagrawal538]

the best explanation on the internet

[@tasneem6427]

Please upload all these before our board exam commence 😭

[@justlearn3444]

I am also waiting for the same Thousands of videos on Internet But you are our gem and resonating factor ❤️

[@mitchinyauja]

i swear i literally smiled so much after this lecture, it just made inductors so easy oh my god. i really enjoyed this video, i love this method of teaching, plus the language was so clear and friendly voice, it actually felt like i was just hearing a story wow.

[@solapowsj25]

You're good at teaching students high school and college level. Keep it up. 👍

[@dkioko6819]

The d.c supply does not produce changing current.Current in a d.c circuit is constant.For you to have changing current hence changing magnetic flux you ought to have use a.c supply in the circuit.

[@yoramalon5273]

How an indian explain things , straight to the gist, simply and logically. I think India must be an intellectual superpower. I like indian people.

[@dishajariwala9741]

This is actual learning of physics as there's no focus on just mugging the formulas but it is actual concept

[@uzairhussain4856]

10 by 10 for you. This is how physics should be taught.

[@SriPradha.S_1027]

what i had studied in my school days , inductors are short circuit for DC , but now i understood that i was told only about the climax and not the complete movie..thanks tutor for the animation and your amazing explanation...!!!!simply WOW

[@sparsharegmi]

Awesome lecture, thanks sir

[@mike-df3qo]

Dude I've witnessed so many teachers and khan academy teachers even, no on is better than this guy

[@som3.14]

I am in love with your explanation..... Real addiction... keep uploading all topics ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️

[@OnlyOne1Dee]

They is something special about Indian tutors, more love from Africa, thank you sir

[@RandomerFellow]

Absolutely brilliant explanation of the subject.

[@Ansh_Dhillon_]

And the conclusion is that the battery and Inductor are arche enimies 😂

[@harshguptaxg2774]

These videos have left a huge impact on our youth in the way that we learn things, Hat's off to Khan Academy especially Mahesh Sir

This is a FANTASTIC explanation. Thank you so much! (On a side note, however, if the switch is opened, wouldn't the bulb explode first, instead of the us getting the spark? I may be getting picky)

[@nauwwww]

Sir thanks to you I love physics, thans hou

[@dalenassar9152]

GREAT VIDEO!!! I want to actually do this and watch the light slowly (relatively) brighten compared to an identical lamp with no inductor. Would a suitable inductance be much of a problem to make?? I plan to use the time constant (L/R) for reference. THANKS MUCH!
