You know, the whole AC thing just clicked in my head, and the best part is my exams are in less than 12 hours time. Seriously though, thank you so much for simplifying(and reinforcing) what I've learnt in class. Should have come across this channel sooner.
That minus sign is Lenz's Law, and everybody should know it by this point. Obviously the voltage will be induced in a direction to oppose the change in flux, so I am interested only in the magnitude. Thanks for clarifying!
I have a question about that though, if we're solving problems that have to do with flux, does that mean we *don't* add that negative in our calculations ever ?
Thanks! I think I'll do just that next year. Presently, I'm doing the problem-solving in my class with my students. I suggest you tie up a physics teacher and make him show you an example in your hometown. Then let him go and watch your back. We hold grudges.
Thank you so much for your amazing work on these videos! This made me fall in love with ECE all over again and is helping me in the midst of garbage professors.
Very helpful video. What would also be helpful would be if you put an example with numbers at the end to kind of show how to apply all the theory and proofing you do.
Hi Doc.Have you ever thought about the inductor produced the emf is exactly cancel out the applied voltage? The voltage finally applied on the inductor in the ac circuit is ZERO? I know emf is produced by changing current. But you just wrote EMF=applied voltage as well.
I found one difficulty in drawing graphs of sinusoidal main field flux due to source , lenz's flux that opposes changes in main flux , and also thus effective flux in inductor and thus the emf graphs, when a pure inductor is connected to an AC sinusoidal voltage source. Can you please upload them.
Video guide is good. But help me out on understanding how an inductor works with an AC voltage source using wave forms .................Things like : HOW WILL BE APPLIED SINUSOIDAL VOLTAGE GRAPH HOW WILL BE CURRENT THROUGH THE CIRCUIT HOW WILL THE FLUX BUILD UP AND INTURN PRODUCE ADITIONAL EMF AND THUS INDUCED CURRENT AND HENCE THE LENZ LAW FLUX............................... WAVEFORM OF HOW MAIN FLUX AND LENZ'S FLUX WILL AID AND OPPOSE EACH OTHER IN THIS PROCESS USING WAVEFORM ANALYSIS......................? PLEASE PLEASE PLEASE.......................THIS DOESN'T LET ME SLEEP AT NIGHTS.

I choked on my cookie when you said, "and the inductor will get pissed!" haha.
You have no idea how much you helped me in my studies.
I'd very like to watch LITERALLY all your videos, if only I had the time.
Great!
omg my dream teacher !

I've been so confused for the past 3 weeks on this stuff, but this video clears everything. Thank you so much!

The world's best teacher thanks
I am addicted to these videos
Thank you so much for your amazing work on these videos! This made me fall in love with ECE all over again and is helping me in the midst of garbage professors.
Thanks Doc Schuster! You made me fall inlove with Phasors!
I love the use of low tech crayola on paper to teach, old school, like reading a real textbook...
Best of the best! Thank you Sir for your generosity
I LOVE THESE VIDEOS! never ever ever stop making them
Thanks to you, my friend, I am going to pass this exam! :) Keep doing the examples with the Pi/2 phase shift.
The current goes Shhhhhh! The voltage goes Kachtooo!
i love this guy! xD
I have a final lab exam tomorrow, You saved me Doctor :D
Where are you today's

electrical is my branch so as your channel is what i need to subscribe. thank you sir
Thanks Doc Schuster, thumbs up!
WoW, this was the best
Lovely explain

man u r the best
love this guy
Man..... U R great 👌
Holy shit dude! Great video. Where did you go to school?
Thank you sir. what's about numericals
You are weird but you are great. Doc FTW
I wanna know why V=L(Di/Dt), it suppose shoud be V=-L(Di/Dt), where si the negative sign?

You sound like Ryan Normandin, that MIT guy

Inductor will get pissed😜😂😂
21 of people who disliked this video you know are those who fail in class.
At 8:20, cos(wt) should be changed to sin(wt - π/2).
You are confusing co functions.
Haider Rehman Butt Except for a minus sign, those are equivalent, right?
+Haider Rehman Butt cos(wt) cannot be changed to sin(wt - π/2) because it is false
+Haider Rehman Butt bro, a little knowledge is a dangerous thing
you have a butt in your name
@@DocSchuster even no minus sir It was perfectly alright
*Draws symbol for ground* "if we add a battery"
David Brandt thats a batteery. Earth has 3 lines
İntegralle ve trigonometriyle bu kadar vakit harcatırken fizik derslerinde bu ispatları göstermemeleri çok saçma değil mi?
I dont understand

Why don't you admit you don't really know
be more serious when you explain things ... we are not playing video games here ... !!
