I rarely comment on videos. You are literally amazing. You reinstalled a love for circuits and physics I had in high school but thought I had lost in engineering college. You are clear, concise, informative, hilarious, enthusiastic and above all make complex subjects simple, relate-able, and understandable. If there is a teacher of the year award I can nominate you for let me know. Please never stop the enthusiasm or making your videos, they have helped me regain a love of learning in as senses! You ROCK!!!!
I have to pause the video to write the comment. You are just amazing. I am trying to explain this to my kid, it takes me forever. You nail it. Thanks for the video.
this is literally the first time I've ever commented on a video despite having been on UA-cam for almost 10 years (?!). But I just gotta express how I LOVE how FUNNY yet informative you are. I don't think I ever laughed so much learning physics before!
I have a horrible teacher for my freshman year's physics classes, and thought of changing my major because I wasn't doing well and I found the concepts so convoluted. Your videos has reminded me why physics was so beautiful and interesting again! Thanks!
I swear I'm hooked up to this guy, the way explaining things makes me feel like I'm hearing ot Richard Feynman....Man you are soo good thank you from the deepest of my heart
You are a very clever and brilliant teacher. Today I asked me what is a tank circuit in wanting to experiment with TRF radios and you fired me up. Then I likened it to the energy of motivation. Thank you.
Reactance creates Impedence creates Resistance. Drop a piece of paper to the floor (not crumpled up). The Reaction of the paper falling creates impedence against the air which creates the resistance that causes the paper to not fall straight down. I really love how excited you are :)
Thank you so much Doc, I found your youtube channel last night and I watched all your alternating current videos and now I don't need to mug up those phasor diagrams or the formulas for impedance, it all actually makes sense to me. Thanks to you I have fallen in love with physics, the subject I hated 2 nights ago. !
Amazing bro ...I am really impressed ...I have also made a radio station ..at home using this property of capacitor, inductor and resistor ....nice to meet you ...awesome ...fantastic ...I can't explain how happy I am after watching your video .....🤓
For a parallel LC circuit, the impedance would be maximum when at resonance frequency. Your connection seems to be in parallel but it acts as series connection. Series or paralell?
If I had half of his excitement for phisics I would already be a decent student 😂, since I'm a chemistry student every time he gets more excited I get more annoyed by how can someone enjoy this so much, but the explanation was really solid thanks for the video
Doc Schuster I'm in second year electrical and computer engineering. Since high school, I am always very good at dynamics and classical physics but not electronics. I just felt electrical stuff are not as intuitive... and your video just blew my mind, I never treated electrical circuits as physical components before. If I saw this video last year I would have done much better in my second year circuit courses.
I indeed understand how the inductor initially resists the flow of current, but I don't understant is how it does not simply consume the potential energy from the capacitor killing the oscillation. Can anybody explain? Thanks a lot.
@ 9:10 you said that the inductive reactance is equal to the capacitive reactance in a series circuit. You are saying only if there is no voltage right? Because the capacitor could be 1uF and inductor 1mH, with 1kHz input (1/2pifc and 2pifc) means they wouldn't be equal.
My question is how the instructor assumes that current are equal both C and L in paralel combination. It must not. Because the magnitude of current varies depending on resistance of components ????????
Doc, it a really nice explanation of resonance, but I have a simple question regarding resonant frequency, I would like if you could make a video on how to solve this simple question. Here it goes. If a 200uH whose resistance is 5 ohms and is connected is series with a 200pF capacitor, what would be the resonant frequency of the combination. Hope you can make a video. Moises from Belize Central America. Thanks a lot.
at 1:48 it says that the same amount of positive charge will build up on the previously negative plate, causing the "polarity" of the capacitor to change and start pushing in the opposite direction. This confuses me because I though that once 50% of the charge has left one plate and ended up on the opposite plate, there will be no net charge difference on the plates, and as such the voltage would be zero, causing the current to come to a permanent standstill. Why doesn't this happen? Or is this just a flaw in the video?
Andrew Muller Consider a pendulum as it passes through the lowest point in its cycle. Why does it continue despite the fact that there is nothing pushing it?
There's just one thing I don't understand. At 1:08, you said that current will flow clockwise, i.e., from the positive to negative plate. Please help me make sense of this.
Back before they knew that current was actually caused by the movement of electrons, they naturally assumed that the "electrical motion" per say, was going from the positive to the negative. So if you had a capacitor with a positively and negatively charged plate hooked up to a circuit, the assumption was that the electrical charge was moving from the positive to the negative plate. Nowadays, we know that's actually not what's happening. The particles that carry the electric charge along the circuit (the electrons) posses a negative charge, so really what's happening is the negative charge is moving to the positive plate. Because of this, what we define as current is opposite the flow of the electrons.
Great video! I asked earlier about using complex numbers for periodic motion, I'm still a little confused as to why Euler's identity is sometimes used instead of the sin and cos functions. It is because e^ix is also periodic right? Does the imaginary unit appear when one is calculating impedance?? Btw nuclear magnetic resonance?!? I know what I'll be researching today, and my grandmama says thankyou for looking out for her
Good God Dude, did you get into the sugar bowl again. You are not the typical back yard mechanic are you ! PLEASE SLOW DOWN for us regular people ...... still, good vid.

Subscribed and liked. Keep it up Schuster :)
👍
Today many animated videos have taken over the internet but the vibe these old yt videos give is Just incomparable.

Hands down the best Physics teacher 👨🏫
I dont often comment but this is great. Your teaching style is awesome!
Very well and exuberant delivery. Your Math explanation is super. Spring constants Hooks law it's all connected. Thanks.
This is the best class I have never had better than that before!
Thanks for the videos. They make school so much easier to understand and keeps it more interesting. Please keep them coming.
Thanks, Evan! I'm on it.
3rd year into my polymer engineering course and I still look up Doc Schuster for my physics ❤️❤️❤️❤️. Please make more videos. I love your channel
I like the way you teach. Very easy to understand.
OK, this is my favorite channel now for the power systems person in me.
Amazing bro ...I am really impressed ...I have also made a radio station ..at home using this property of capacitor, inductor and resistor ....nice to meet you ...awesome ...fantastic ...I can't explain how happy I am after watching your video .....🤓
Thank you. I really like my current job, though!

Subscribed without hesitation! Excellent job. Full stop.
We need this in electrical engineering labs. Thanks for the great content!
wow so much enthusiasm in one video... I LOVE IT!
I've been confused on this so long, this video was extremely helpful
GREAT VIDEO LECTURE SERIES PLEASE POST MORE AND MORE SPECIALLY RELATED TO COMMUNICATION ELECTRONICS
Holy eff-word this video just kept getting better and better!
I love your enthusiasm, .akes me want to go to my radio shack and play with this ckt.
Keep up the good work
First time circuits made sense to me by your awesome lectures! Thank you soooo much!! Please keep rocking those physics! :D
If I had half of his excitement for phisics I would already be a decent student 😂, since I'm a chemistry student every time he gets more excited I get more annoyed by how can someone enjoy this so much, but the explanation was really solid thanks for the video
best teacher ever
Aw, shucks! That's just over the top, man. Thanks, though!

Great work you helped me a lot thank you!!!
I wish every of my classes were like this!
Thank you 💪This corrected much I wanted to learn at college!
Thanks pal; next time I think of oscillating circuit I will think of granny's rocking chair.🤣🤣.
this video is simply awesome !! thank u so much sir.....
genius explanation sir! all physics come together
I'm so glad you like it. This was the MOST fun to make.
That's really cool, I will teach my students in this way. Thank you.
simply brilliant sir
great insightful video, thanks doc!
I suspect Doc Schuster might be Afrotechmod!
He has a similar voice, good way explaining and interactive.
I wish I were Afrotechmod. I consult his videos before I build stuff!
could you tell me where did the imaginary factor go when we read about the reactance its like jwL or jwC?
Beautifully explained Doc... but throttle back on the Prozac a little :P
Muchas gracias excelente vídeo.
the best i ever see
Have you considered rehab?
Grandma fell out of rocking chair....XD omg I love you man
Is the lowest/minimum impedence the value of the resistor's resistance, say if the inductive and capacitive reactance cancel each other?
Well _done._
Unreal video! Thanks man!
Thank you. I had a great time making that one.
You're batshit but also the most clear at explaining electronics... great video!
still gives benefit to me in 2017. thank you! but almost had heart attack whenever you shouted in joy when figured out something..hahaha
Yay! No problem!
Lovely! Thanks.
Hows the current thru the capacitor and inductor the same??? They're supposed to be parallel???
Incredible man...
Loved this, thank you..😊
I indeed understand how the inductor initially resists the flow of current, but I don't understant is how it does not simply consume the potential energy from the capacitor killing the oscillation. Can anybody explain? Thanks a lot.
Wow amazing, thank you!
Beautiful. LC tank = electrical pendulum. Thanks for sharing :-)
Isn't the the impedance low at resonance for series LC? For parallel LC circuits you should get a max impedance at resonance.
when Xl=Xc it is said that the circuit will be reso. But what happens when you change the capacitance?
I am really enjoying this :D
Nice video, thanks :)
You're a genius! Thanks
Great video thanks

Omega = 1/sqrt L x C
Put values there and you get it.
I understoood!!!
what is the function of inductor coil
Doesn't negatives move to postives, though?
Correction at 2:00 - there is no charge on capacitor. The reverse current is driven by coil through induction and not by capacitor.
Man your amazing.
What is the application of Resonance?
what does a phasor graph look like with RLC all together?
Impedance from L and C are pi/2 out of phase, so they will attempt to cancel each other!
Sir why I is rms but not I max??

you are awesome!
Laverne wants the letter off of her sweater back
I feel like Barney from How I Met Your Mother just taught me LC oscillations.
Thank you!!!

The imaginary term is hugely useful - it's a pi/2 phase shift, like you will find in my phasor videos!
"You've had a mouthful today. Good luck!"
MAXIMALLY!
ur awesome
Its so complicated there is no simple way to get this doc ?
victor vance I put everything together in this video, so it would be a tricky place to start. Watch the ones that come before it in my playlist.
Good God Dude, did you get into the sugar bowl again. You are not the typical back yard mechanic are you ! PLEASE SLOW DOWN for us regular people ...... still, good vid.
At resonance frequency Xc = Xl which means that Z total = R. Please fix your graph
amplitude ,its all abt amplitude lol thanks for video
14:56 LOL!
Doc Physics is no squirrr
mindblow :)
KILL ME NOW, i understand it so thanks but it's so much ahaha
👌
this spring its not inductor but it looks like one ..hahahaha..10:12
oooo shoot.
wow
You didn’t say why I dicta nice impeads curre nt flow
Your L looks like a z. but nonetheless marvelous explanation
Had to watch this twice...too much information at once!
Any ham radio operator come here for they extra license?
👏👏👏😂🤣👏👏👏
