Intro to AC Circuits using Phasors and RMS Voltage and Current | Doc Physics

We will use a cool method of describing the oscillation of current and voltage called phasors, which are fixed-length vectors that rotate at a constant frequency. It will be very fun. Yes, really.

India is awesome. Indians are some of my best students. I want to go there someday!

"sqroot" hahahaha omg I love that!

Thanks so much, I'm in first year engg and I need to pass this course.

Disha - work problems.  Find a friend who is about as strong as you are in class.  Work problems from the chapters that gave you the most trouble, and check them with your friend.  And then work more problems.  If a concept gives you trouble, watch a video, but then work more problems.  Good luck.

You just dispelled the mystery of RMS for me! Thank you!!

[Dr_MW]

"Shoutout to India.."
*grins*
Shoutout to you too for this amazing vid. Hats Off!

[DocSchuster]

You've got so much time on your hands that you say Square Root? Consider yourself lucky. I'm a busy man.

After 9 years, this video is still so useful. Kudos to you professor.

You're a good guy Doc. As an apprentice electrician trying to discern meaning out of a vague, cryptic textbook, I appreciate these videos immensely.

Wish my teachers explained in this manner..i guess my whole class would have topped then..anyways..u kept me focused all the time with your strange but cool way..cheers!

Ryan Reynolds probably took vocal lessons from this guy.

This is such an amazing video, your enthusiasm is so infectious. I could barely bring myself too study this topic for 5 minutes before this video and now I actually enjoy the topic, thank you.

[crhee]

Why can't all professors teach like this.

[danielespinoza]

I just want you to know that I love you. Nah, but seriously dude your videos are saving me in class. I learned more from this video than I did an entire semester of circuits

[jean-gabriellacombe]

I usually never comment on Youtube, but just had to thank you for this! Absolutely brilliant

[goku]

You make Physics so much interesting! Thank you Sir! Crystal clear concepts!

I have just started my electronics engineering at one of the worlds so called "top " universities, and I have struggled so much in keeping up with the course as they expect you to just know everything and do not explain things properly. I stumbled across this video and you explained this topic in such a beautiful way that I can finally appreciate what a phaser is and what the rms is. you could put a top professor to shame that is how good you're teaching is. Please continue your amazing work. Just goes to show that these universities are just great by name but when it comes to actually teaching their horrible waste of time and money. Most importantly thank-you for making learning fun and not a tedious regurgitation of knowledge where we do not know what anything does but we just memorise.

You're a legend. Thanks for making my electromechanics class bearable

[Hassanw]

man im so glad i found you i have a electrical quiz in 2 days and exam in 8 days, I've learnt more here than i have in like 5 lectures... appreciate your work, defo subscribing

[lalnazochasev]

A shout out to india? I love you even more now! You're a really good professor! Also, sqrt.= scroot? Lol you the best!

[rafay_syed]

Thanks so much! I have a physics exam coming up in three days and I was confused on AC circuits. This video clarified so much for me! I am subscribed :)
