1:12 The complex exponential function and sinusoids
3:24 Phasors
4:46 Addition and subtracting phasors of the same frequency
5:15 Addition and subtracting phasors of different frequencies
5:40 Fourier Transform as a sum of phasors
6:02 Approximating rectangular function as a sum of phasors
6:20 Frequency domain
7:18 differentiation and integration of phasors
7:30 resistors
8:07 inductors
8:43 capacitors
9:18 impedance
10:55 How capacitors conduct current
13:47 why voltage and current of the capacitor are 90 degrees out of phase
14:26 the response of a sinusoide is also a s inusoide
15:24 decomposing the step input signal into sinusoide (getting the frequency spectrum of the signal)
16:12 getting the response of the circuit to each sinusoid contained in the input signal then adding all of them

I'm in tears at the sheer beauty of this animation. The fact my years of education is allowing me to understand what he's saying effortlessly makes me grateful to life in every way possible.

For years I’ve tried to demonstrate to my peers how a photon “travels” through multiple axis and my friends couldn’t grasp my vision (maybe my explanation was rubbish) now I can show them!

[guliyevshahriyar]

Thanks for the precious tutorial. It's the reasons Youtube still is on top having such helpful content makers.

[blitzkringe]

Your animations get better with every video. Nice work.

[saifahmad]

DUDE this is something i meen not to compar and all but you could be the 3 blue 1 brown of electrical engineering . im serious

[gabrielevisentini]

This is absolutely brilliant, thank you so much.

[jaybrown]

Very interesting video. I studied all this years ago but we didn’t have such interesting presentations back in those days it was just math. These videos help in the understanding of this topic. Great job!

[anubhabtarafder]

This video is a gem. Thank you for making my concepts clearer.

[iwbnwif]

This is an excellent series of videos, I am really glad your channel is starting to get the attention that it deserves.

[jaybrown]

What great video’s! I wish they had been around in the 70’s when I was in school studying electrical engineering it would have made things much easier to comprehend.

[KaneBear]

Wow, never seen such a good animaion about imaginary part.

[eecuriousener]

Great videos, please do more videos like this to help some learners to visualize math. I really appreciate your videos.

[learnergood]

Superb video, it's very easy to understand concept using such animation. Thank you very much for making such explanatory video.

[benrasmussen]

thank you very much, it makes it much easier to understand when your presentation is so well put together

[geometry_manim]

Excellent animations and story behind! Thank you for sharing source code

[AKfire]

Very very good video.. Cool animation. Keep up the great work..

[parthapodder]

Please, mention the softwear you are using to do the simulation. I will really appreciate your effort.

Bro HOW YOU ONLY HAVE 2K SUBS!!!
This is great content thank you so much and please keep going

[mohamedmouh]

thank you very much 🥰😍🤩. that's was simple. excellent explanation.

Excelent to understand the complex numbers which we calculated without a concrete purpose
