Mahesh is so underrated,
He deserves more attention and praise for his outstanding teaching ability, how he breaks down complex concept of physics into simple terms..
great explanation, as always!
Agreed. Hes a fantastic teacher
Sir you deserve a nobel prize for teaching
Yet we reward with poor pay
no he doesn't
He is not that great
Why@@sirii3438
And you also deserve a Nobel prize for this type of comments 😂
Broo I'm literally being honest...i don't like it when teachers just give us a set of formulas to memorise and apply them in numericals w/out even making us think or ponder...I swear I literally liked this video within just 4 mins..You guys are the only one who actually gives the feel of physics....it's so saddening that khan academy isn't even popular
Mahesh sir is one of the finest physics teachers👏
No word can carry my zeal, nor could have any intelligent being that lived... Ay, the perpetual bliss but to reconcile with the wondrous beauty of nature that we are so devoutly yet unbeknownstly attached to. Let's have a time together to commend on the astounding process through which the great theories of nature unfolded unto mankind...Nevertheless, consciousness plays dice!(Prick a thorn unless you accord with the phenomenon of Quantum Entanglement)Right reverence and gratitude unto Sir James Clerk Maxwell who showed us to the portal of this great theory and of course to Mahesh sir, who reiterated it in words so rich, so powerful...
indeed! it is quiet the theory. sir mahesh has a way of words, words so inspiring yet so attractive to one’s ear.. i’m afraid i may get out of hand with my thoughts so i’m afraid i have to end it on that note!
Yup, it's lit 🔥
Much better than most JEE/NEET channels.
this man's storying telling skills are top-notch LMAO i was ENGAGED like pls tell us what Maxwell thought !! had me on the edge of my seat
Gone through many videos but see how smoothly and easily and step by step he teached it. Fabulous. Award winning. Thank you sir.
sir u actually made me fall in love with physics. ur way of explaining concepts is SO GOOD. thanks a lot
Excellent! A confusingly named concept - displacement current - given a lucid accounting. I wish as a physics major, decades ago, I had access to this video - instead of our E&M professor just introducing the term with little explanation.
Great handwriting, great English, great enthusiasm for physics.
Watching one of these videos is like watching a great movie/following a story, wanting to know how it all ends. Thank you
Great video on a difficult concept. Keep it up. Students around the world would love to see more of such videos on different topics in science.
Best explanation on the internet! 🙏🙏
exactly
exactly
BEST TEACHER OF ALL TIME HE DESERVES A PROMOTION ❤
I've heard of people raving about Khan Academy but now I know how amazing it actually is
It is the clearest explanation ever what I have heard. The style of video is amaizing with all this manual drawings.
Terrific explanation!! Thank you so much!
Dear sir, am an educator, learning how to deliver physics concepts to students easily from you easily sir. 🙏🙏🙏 Thank you for these works. Keep transforming🙏🙏🙏
This is gold. Thank you!!
Fell in love with the way you were teacher Prof, Im going to watch the whole series of these videos just because I loved it and made the concept really clear.
damn....no one made phy tis lovely in my entire school and college days ......my long pain is cured...tanx
Great Teaching skills ...Appreciable
you are just brilliant, your way of teaching is just.... I am short of words, absolutely amazing, keep coming up with more physics content sir.
you're an amazing teacher, today i understood a concept i have been struggling to grasp for a while. thank you so much sir!
this is an excellent explanation
hey sir, your work is invaluable.
wish for you the best of luck in new year
What I wonder is the explanation of displacement current. I also thought it can be named wireless current. Hats off to Mahesh Sir
Great explanation!
You Are an incredible person!!
I am really speechless how in 10 min he made me understand difference between conduction current and displacement current
Love your work from my bottom of 💖💕heart
6:20 My Eureka moment. Khan academy, Iam really blessed to have you.
sir your videos are brilliant, each concept explained so simple yet smart, thank you so much !
Woah Sir,
You ignited my mind
I hope more teachers were like you ✨🥺
This teacher deserves an oscar!!
So underrated
Much thanks!
This is the best video for displacement current
I literally don't have words to express how grateful I am to you sir 🙏🏼🙏♥♥
Wallah this guy is a legend, Thank you
Thank You !
so great my friend in every thing choose the information , choosing color to explain, your hand write , and you clear English language , can i ask you the name of the software you use
most underratted channel this is
Great explanation, thanks😀😀😀
thank you very much this expanation is perfect 👌🏻
U are the best teacher ever I learn from
really super, thanks so much
thanks very mush for ur vedios
Thank you for this valuable video
i bassically love the explanation.
Fantastic!!
thank you so much mann ive been reading books watching several top indian lectures but understood nothing it was to complex for me perhaps u made this so easy for me
Every time i had any confusion your videos are the only source to vanish it.
Feelings physics for the 1st tym 🤩
thanks so much sir , the way your teaching is so interesting 😁
awesome session sir!
Great explanation!!!!!!!!!!!!!
an award should be made on your own name for great teachers
Thanks Mahesh Shenoy sir😊
what an explanation !
Thank you
thank you kind sir
Excellent
Superb 🙌🙌🙌
khan academy is super underrated bruh ngl
Woohhh nice presentation sir❤
Superb 😊❤
amazing teaching
Thank you so much sir☺️☺️
Super explanation😊
Thank you sir . 😃
Very good explanation
Saw many articles and posts but nothing made sense until your video 🙇
Nice video and presentation.
By page 3:50 presence of B at p confirms there is current flow through the vacuum between parallel plate and continue down the remains of circuit.
Vacuum itself cannot pass charge unless it has permittivity which explains the B at q.
So what is in the vacuum that pass charges? It was Aether, a fluid that has no mechanical but electrical properties, which is permittivity. Aether as a fluid attaches to all matter and drag directly with matter in the local frame and drag indirectly in the global frame.

You are unbelievably great sir !! Sir, i have one doubt. can a static electric field create a magnetic field??? If so the differentiation part of displacement current would be zero!pls reply...
The way you explain the concepts really amazing❤....actually I face difficulty in understanding electrodynamics but ur videos made it easy for me
Beleive me sir i have never seen a teacher like you ...you are truly something else 🙏
Hello sir,
I like your teaching style and concepts detailing,
I request you sir please make videos on JEE and UG-NEET
I would be more thankful to you sir 🙏
I reallyyyyy missed your videos
Page 8:00 it should be noted that Aether has no mechanical but electrical property and that there is no particles in it.
Without Khan academy and you Mahesh sir,I would hate physics!!!
I wish I could Like and subscribe to this channel a million times. Your teaching is soooooooooooooooooo incredibleeeeeeeeeeeeeeee😍🥰💝❤💯💖💖💖💖💖💖
Thanks tutor sir! And for concerning Maxwell....🤣
Very unique explanation 👌 I ever seen.
Lovely handwriting
This is a very well explained video. May you succeed in life !
Quite explanatory; however, it would be even great if you had included the derivation of displacement current by using the equations of capacitors. Namely,
C = Eo A/d(distance between the plates)
Q = CV and V= E d
Q = EoAE and EA : flux
Q = Eo F(flux)
then displacement current : dQ/dt which is Eo dF/dt
Thank you
this is one of the great explanation or the understanding level is very high for normal avg student
this chapter is a backlog for me so your video not helped me to learn, you made me as to think as of this generation maxwell
aama thala!
Wow 🥺🥺.... Explanation 😶
Sir why displacement current depends directly on permeability of free space ('Epsilon') but not electric flux
mahesh i have a doubt.... in the wire we have increasing current ...which means varing magnetic field ..this in turn can produce electric field this electric field can produce displacement current right🤔
and one more ..if there is change in magnetic field then ..opposite emf will be induced know..then opposite current which reduces the source current
Sir which board software do u use?
dud u r good
doing great job sir
Best explanation on this planet ( ´◡‿ゝ◡`)
The 'host' for the electric field though in a capacitor with a free space dielectric.........
*_is assumed not to exist_*
and that is a big opportunity in physics. There is a notable wishy-washiness about the constituents of free space (aka the constituents of the vacuum) in physics history
In our EE and physics courses in college, we were taught "electromagnetic waves do not need a medium to propagate"
or in other words, "space is EMPTY"
We carefully note that, in order to manifest the changing electric fields in the vacuum dielectric between the capacitor plates, THERE MUST BE A 'HOST' MEDIUM
Why?
1) electric fields fall off quickly with distance
2) magnetic fields also fall off quickly with distance
3) there are alternating magnetic fields, and there are alternating electric fields striking Earth this very moment...from our own Sun, from distant stars (the light and other frequency electromagnetic waves from them)
The electric charges that originally created those alternating electric and magnetic fields ARE TOO FAR AWAY
The host for the changing electric field in the vacuum dielectric between the capacitor plates must be charge carriers.
Electron-positron pairs for example
😌😌🥳
There is nothing called displacement current. Moving E-field induces moving M-field and vice versa. Moving E-field moves electrons. It is moving E-field which induces M-field not current as current itself is dependent on moving E-field. Since current is proportional to E-field it is used to calculate M-field. Moving E-field applies to both conductor and capacitor.
