Introduction to Phasors, Impedance, and AC Circuits 

Aren't the diagrams the wrong way round for lagging and leading voltage?

You described these concepts really well, and it was backed by some wonderful animations! Nice job, and shoutout to 3Blue1Brown.

love to see the shoutout to 3B1B. love that channel. but also great to see someone continuing in his awesome style! and doing it well!

This was really interesting. I'm a physics student, so this take on circuitry was completely new to me. It's very cool, looking forward to more videos. One criticism: leave stuff on the screen longer. Just another .5-1seconds makes a lot of difference and allows a viewer to digest the content.

I came here and was like "Is this 3blue1brown?". Great video! Exactly what I needed to grasp the subject a bit.

amazing. subscribed. I'm an electrical engineering student. Love the 3b1b tool! Keep on doing this great work

3Blue1Brown , is that you ? EDIT: Just completed the video, amazing work !!

It's so strange getting to this point in my engineering education (ENGR 202, nothing crazy yet) where before this point, all we knew was DC and capacitors and inductors were basically just abstract elements that we learned the mathematical properties of. But now in AC you can see what they do to a circuit! so exciting

Explanation: 10. Music: 10. Overall Learning Experience: 10. Love the content, thanks for the immersive experience Charles ✌🏻

I am begging you man to make more videos on this topic. I really like this work, and I hope you will continue because you help so much. Please

Awesome job with the video, man. I ran away from electrical engineering because things like these scared the crap out of me. This video actually helped to make some of those nebulous concepts feel straightforward and intuitive. Thanks =) Keep up the good work!!!!

Please make more videos like this! I can definitely see you gain a following and supporters. Thanks for the video concise and informative, loved it.

This is the best way to teach concepts. Thank you for using this style for teaching.

i wish everybody copied 3b1b's style of videos. instead everyone's copying khan academy.

I had given up on AC entirely since high school, and came just to see formulas but holyy mother- i finally get it TvT

Thank you for making this video! It's so helpful

Maaaan, please keep up the good. The video is excellent, you really did good job in terms of explaining.

Super cool, I like that 3b1b' style

THIS WAS THE MOST INFORMATIVE VIDEO EVER GOD BLESS SAVED ME PAGES AND PAGES OF READING

this guys giving off 3 blue 1 brown vibes...

this is beautiful

This was super useful, please make more!

very good video, thank you

man this was soooo goood , thank you

just came across your channel! great stuff!! subscribed :)

Amazing video, thank you SO MUCH!

1:42 why the complex plane specifically ?

great video

Thank you so much, this video is superb.

Thank you.

Is the code for this open source?

great background music btw

Do you work with 3Blue1Brown? Your videos use the same animations and music, so I was wondering if you guys helped each other out.

I see that you represent the magnitude of your phasor using RMS value of voltage. I see in other literature that the magnitude is instead the peak voltage. Which one is correct?

My whole half trimester in 3 min :)

But why we need to take complex numbers here??? can't we just do it with Cartesian XY Plane and without using complex numbers ??? what are the advantages and the intuitions ???

Nice vid. :)

Hi Charles , I like your lecture

this video was so goooddd

Voltage and current are scalars. While "phasor" is short for "phase vector," the phasor is actually a complex number, and complex numbers are scalars, not vectors!

why root 2.

Thanks alot 🙏

Amazing

3blu1brown style!!! how???

Can you please share the code for this ?

Hi, I like your lecture

Hello could you test this software? come upon androidcircuitsolver on google

physics 3blue1brown

yooyoyoy this is amazing dude.

Hi! Very good explanation, but I think you're are explaining it a bit too fast, other than that thanks.

i could say those were at least 20 min

Who else came here from Grant's tweet?

You really made me understand my 2-hour course in less than 4 minutes.

great video

Your waveforms (two sine waves) are around the wrong way in your explanation of lagging and leading. The words and phasors are ok. For example at 2:23 when V is at its peak, I is yet to get there, so voltage is leading (by convention time is positive to the right) which is not what you intended. Similarly at 2:38 the waveforms depict lagging voltage.

Do more videos which go in depth on phasors please!! Its the first time I actually found a video on electrical this visually appealing :)

Just what I was looking for... accurate, precise, short explanation. Excellent job!

Thank you! So many poor videos online that fail to properly explain this in 20 minutes. Yours did it in 4 minutes.

please continue this series, your style is amazing

Agree with the comment below, pls leave the animations on the screen longer so viewer can digest. Fantastic animations though. I'd drop the background music, I found it distracting.

best explanation on RU-vid, awesome

This was really really helpful😭😭thank you, and super interesting too, was looking for more videos on AC on your channel, but didn’t find any, wish you had more, you’re really good at explaining 😊thanks for this video super helpful you have no idea

how did u explain this so smoothly?

the amplitude of the phasor can be the peak values ; they dont have to be rms

Not sure why Xc is negative... the angle will take care of lag

Would be great if you did a whole playlist in Electrotechnics.

"Empower the world with your spark of innovation, and let the current of your passion illuminate the path to a brighter, electrifying future in electrical engineering."

Thank you for the video. I have a question, isn't impedance a complex number and not a vector value?

What do you use to make this animations? Or did 3B1B make them?

Resistance is futile! Be susceptive to trying out this simulator! Type circuit solver on the playstore!

Thanks a lot man, I love the animation and conciseness

This is the sexiest animation I've ever seen.

I know this is late but I feel like keeping text for a bit longer and pausing could have been nicer

wonderful. thanks a lot. i mean it. :)

They are really angels on earth 😊

Thanks. From Bangladesh.

Use \sin{2\pi...} in Latex

Make more videos !!

wow

Man, it's a really good video, but even with your correction, I believe you still have the waves plotted backwards at the "leading and lagging" section. If voltage is "Lagging", that means that it hits its peaks and zero points AFTER the current hits its peaks and zero points. So visually the voltage wave should move toward the right of the current in a capacitive circuit. So for a purely capacitive circuit, the voltage waveform would be shifted to the RIGHT because it hits its peak 90 degrees after the current. In a purely inductive circuit the voltage wave would move to the LEFT of the current because voltage should peak first, followed by the current peak 90 degrees later. I urge you to do a couple google image searches to confirm this for yourself. I know it's confusing because you think "oh voltage is lagging, so it goes behind the current", and it's natural if you're reading right-to left that something lagging behind feels like it should go "behind" the other wave. But I'm about 87% sure you have your waves backwards in that section.

thakn you so much

Excellent. Thank you so much. You have made something great, inspired by something, but you pushed it through to the fresh field of engineering. Wow.

AWESOME! You totally nailed both 3Blue1Brown's style, and his ability to explain a topic in a very easy to understand way. I've been watching lecture recordings on repeat for hours and they don't hold a candle to this 4 minute video.

Excellent tutorial video, thousands of times better than my instructor’s explanation.

X is not imaginary, it is very real. But it is represented as tje imaginary part of a complex number, and people make the assumtion that it is not a real thing. Other than that, this was very well explained, but please stop saying Xc and Xl is imaginary.

what

Thanks!

Bravo!

This was the most intuitive video I've seen for under grasping phasor concepts, it was a nice refresher to me.

if the output of voltage of RL circuit is taken to be the voltage across the inductor, the circuit is said to be what

This is a superb video. I have not looked at material like this for many years - decades actually - and this little discourse brings it all back in a quantitative way.

This is so helpful and clear!! Thank you thank you thank you!! 😭😭

hi sir im one of the final year students majoring in chemistry, just wanna say my gratitude for making this video, u just save my ass

Grant shared your video on twitter

Please share code on github

No you are great, you absolutely should be plagiarizing 3b1b

Really like the use of the animation software that 3b1b uses

nooooo where were the "future videos"? :( This was such a great video

You, Sir are the beyond amazing!!!

please do, i love this as much as Grant's videos. We need more videos like this and yours!
