- 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!
Doc Schuster Ur have a great skills I love you...
How about Egyptian?
great work..
Thanks doc
Welcome
"sqroot" hahahaha omg I love that!
Thanks so much, I'm in first year engg and I need to pass this course.
we all need to pass
*screwed
Do you study Engineering at the University of Victoria in British Columbia/Canada?
When you don't have time for extra syllables.
You just dispelled the mystery of RMS for me! Thank you!!
"Shoutout to India.."
*grins*
Shoutout to you too for this amazing vid. Hats Off!
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: ahan??
me: O Yean!!
Ryan Reynolds probably took vocal lessons from this guy.
dude. You made this video 10 times better, cos now I'm thinking Ryan Reynolds is teaching me electrical engineering.
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.
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.
Why can't all professors teach like this.
C Rhee bcus they hate their jobs
University of Victoria, British Columbia, Canada
After 9 years, this video is still so useful. Kudos to you professor.
I teach an electrical apprenticeship and have found your videos to be a great resource. You are a fantastic teacher! Thank you so much for your efforts here!
You're a legend. Thanks for making my electromechanics class bearable
You've got so much time on your hands that you say Square Root? Consider yourself lucky. I'm a busy man.
LOL
Why not just root
Why add square
Why not find avg of the absolute value of sin instead of sqr of it?
@@sarthakrawat7748 we say square root because you can also take cube root, 4th root . . . nth root, so we say square root in order to clarify that we are not taking any other root,
The way you say it is like nails on a chalk board though. Maybe it sounds cool to a girl in high school
these videos are so helpful. seriously i didn't get this stuff after weeks of practise at A level, but now I'm revisiting it at University you've helped me learn this in 10 minutes
Your enthusiasm makes learning fun. I just started AC and it's giving me a bit of trouble, but alas! The Doc is here to help!
squuurrrrrr
skroooot
lol You beat me to it by 3 years. =P
strange!
You really make up for the lousiness of my AC electronics teacher. Thank you!
Oh, and your pronunciation of square and square root is adorable.
Great video! I would highly recommend including links in the description to your other videos continuing on from here, this way people can watch several of your videos on a topic with ease.
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!
Hey Doc schuster , you present these complicated things in such simple and innovative ways it just makes me wanna love things even more and more....
You are a great teacher. Thanks for making eveything easier and more visual than my educational system does :D
Thank you for the lesson, it really helped me. You are a gentleman and a scholar.
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
You make Physics so much interesting! Thank you Sir! Crystal clear concepts!
And Thanks for the indian shoutout :D
Your videos are brilliant! You make everything sounds so simple...
These are absolutely incredible. Awesome instruction. THANKS !!!
love the way you explain, just keeping it active and interesting!
This at 1.5 times is even more amazing. Thank you.
This is a truly beautiful explanation. Thanks for taking the time to make this vid.
Sir, greetings from Romania, by far one of the best educational video about AC, RMS...sir you have indeed a lot of patience, unfortunatley my university proffesors are lacking this kind of skill and interest, they just read the power point....i wish you all the best and keep up the good work!!!!
Thanks Doc Schuster, I was looking a video to refresh me the AC principles , and this video was the best.
best teacher ever. you make learning physics so freakin exciting lol
omg, you have so much passion teaching, that is amazing! i wish all my teachers were like you!
what an awesome way to teach circuits
your voice is very fun to listen to as well
Writes with crayola, teaches logically with the right bit of fun, you make learning fun again.
A shout out to india? I love you even more now! You're a really good professor! Also, sqrt.= scroot? Lol you the best!
Excellent presentation! Thank you for spending your energy making this for us, it was very helpful! A+ in life
Doc, You are a life saver..No Kidding!
Half way through your video and I can already say its amazing! Well done :)
Thanks, Ali!!
I usually never comment on CZcams, but just had to thank you for this! Absolutely brilliant
do u have piles
oh this is really helpful and hilarious. especially when you called every variables there as 'suckers'. thank you
Feels like i am watching saul goodman teaching physic while watching ur vid, great tutorial man saved my ass on the final!
Wonderful mate..my friends in india are loving your teaching..good job
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 :)
I'm glad to have you! Go get that exam.
This channel is great! You gotta love the professional crayola markers. :p
"Scroot it..."
I'm stealing that phrase, thank you
Please, share the love! Ain't nobody got time for that.
It's changed how I'll talk about math not for the rest of my life.
lol you say "screwt" and "sqwur" for square root and square haha anyway great video saving my life in physics.
no - he's saying sqrt and sqr like on a calculator :p
I can't believe I haven't been using that way to say it for so long. It saves so much time, I was all screwted.
Thanks, good steady-state explanation !
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.
which university is this
You bet, and I'm glad they're helping. Electricity is one of my very favorite physics topics!
Best video so far! loved the energy :)
i thought i heard "screwed", but then it was sqrt. phew.
You're a savior! This helped me a lot! Thanks!
I am so facinated over how much you seem to enjoy teaching this. I never got why you'd take the half of v_max^2, but your way of showing it just made an AC-ligh bulb go on in my head! Keep on the EPIC work! :)
Cheers!
Thanks, man! Did you ever wonder how much the power output from an AC incandescent bulb varies with time? The temperature must be quite stable, because power radiated goes like T^4.
Doc Schuster No, but I kinda do now.
...excellent. [mysterious, slightly evil laughter]
Skroot....Gotta say this is brilliant. In the first few moments I thought, 'this is going to be rubbish', but wallop it grew quickly to max coolness.
man, when you said "hello everybody in India!", my eyes just shined really bright.
i can't represent every guy in here, but, i personally LOVE your work!
cheers! wish you all the luck.😜😜😜
Ur a champ had a lecture the day and didn’t get it at all, but this really helped!
I have an oral exam tomorrow and your videos saved me, thanks!
You are AWESOME!!! Thank you soooo much!!...
Hi there! I'm busy studying for my finals and your videos have really helped. Thank you!
Very beautiful. Thank you so much for that amazing video
Loved the yeep sound effects!A solid thumbs up!!
This guy is sassy, I like him. You and Lasseviren1 have saved my grade
you made studying fun.... thank you... this video is really helpfull
Thank you so much for posting this video, really helped out.
I know this is an old video but I dislike all the comments about you being on drugs because you're "too enthusiastic". On the contrary, I loved it! This was super helpful and I'm at the start of my AC analysis class. Thank you for making this!
Thank you for the video.. And much love from India.. 🙏
So much easier to understand than class lectures! Its a bit quirky, which makes it fun and enjoyable to watch! Sqr... lol
Amazing tutorial 👏🏿. Thank you so much
This helped so much. Thank you!
Sounds like me explaining things to myself, only I couldn't explain AC circuits to myself because I didn't understand them. Thanks for this lovely video!
I like your enthusiasm
Great job. Love your enthusiasm! I can tell that you really enjoyed making that video. :)
That was fun! Thank you for this!! I'm gonna binge watch physics vids now LOL
This is so sick! God damn good!
I have my final exam tomorrow. Thankful is an understatement!
Thanks, my prof was using phasors all over the place and I didn't even know that they represent sine waves in the way that you showed.
Thank You!!! I am also Indian...
Also I like the way you teach... It's just AWESOME!!!
Love you brother... Keep up with your videos... It helps many of the students...
what an awesome video/explanation!!!
keep the good work
oh even tho i knew these stuff i watched this vid. I LOVE the way you teach. wish you lots of luck! :p
I learned more about math from you in the first 11 mins then I think I ever have in my whole life. Everything is seeming to make sense now.
Yay! Math is love!
MVP! Thanks a million!
Thanks for explaining the math concept behind the rms value. Most people just throw it out there with no reason as to what that means or why it’s important
This is an awesome video, you are a great teacher!
You're awesome at explaining this! Thanks man
Thank you! YOU'RE awesome at self-driven learning. Keep it up.
I agree with what you've said. My phasor for Vmax is pointing in some arbitrary direction, so it represents V at some arbitrary early time, as you've said!
However, I call the phasor Vmax because that is its length AT ALL TIMES. If that makes sense, you are ready to rock phasors.
U saved my days....it's really cool
Dude, you're amazing!
This is amazing. Very well explained and I respect your energy and enthusiasm.
thanks for all those videos really helped me alot
bruh he is coooool, Thank you sir, greetings from the Philippines
great :-) . I love this , well explained with fun.
Vmax is the magnitude of V. Got it! Great video thanks for the help!
Wow! You are great! Thanks a lot!
Yes, India having been an English colony uses 50 cycle mains power. They also still use older English standard outlets. About the ONLY places that still use 60Hz are Canada, The USA & Mexico, (and a few Pacific islands). 50Hz is slightly less efficient going through a transformer, but not noticeably so. 25 Hz power required a beefier transformer, and some products had a 25Hz option for people living around the archaic power houses in upstate New York & Canada. That system was finally retired after NAFTA went into effect that those old factories back east closed down & relocated to Mexico. They clung to that 25 cycle power supply citing that retooling would cost too much. Moving to Mexico was not a problem, with the cheap labor, and 25Hz power went the way of the steam engine, the model A Ford, and telegrams.
+Seth B Wow! This is very cool info. Thanks!
+Seth B What do you mean by "went the way of the steam engine" the majority of the worlds electricity is generated by steam power.
Great lecture ! Thanks from India 😀😀
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
Hassan Waris 😂 mine is on Thursday bro
godwin enoch how come??
Hassan Waris 😂 😂 you over slept bro
+Nathaniel Weaver exam tmorow, beat that!!
+Glytur Elsa Exam in 4 hours.
If I were a good professor like you, I would be such happy guy!
awesome Mr. Concept!
You are amazing!!! THANKS !!!
Awesome, very clear explanation!
