Introduction to AC Circuit Analysis (Full Lecture)

In this lesson we'll introduce basic AC circuit analysis techniques. We'll learn that Ohm’s Law and the power equations are valid for sources that vary not only magnitude but also polarity as a function of time. Additionally, we'll learn to calculate average power and effective voltage and effective current values for AC waveforms. (Full Lecture)

The smoothest transition from DC to AC! This video is a classic that should be taught in all basic electrical engineering classes. Thank you, Jim. You rock!

[@treverkirk8110]

Its amazing how I always have to go back to the basics, and every time I start to understand the significance of the basics even more

[@hekk_tech5975]

thanks to you jim after watching all the dc circuit analysis course of yours I scored 100% in my exam (i am studying in germany). I am starting ac circuit analysis and before I do so I want to thank you again and again for this content. It is really the best content on the internet right now. thank you very much!!!!!

[@bigbadtech]

Very nice! Please tell your friends about this resource.

[@voltampscircuits]

Amazing! 🤯

[@Gamechangerr667]

Thank you so much Professor Pytel ! I'm a junior studying Electrical Engineering. These videos are super helpful to me.

[@bigbadtech]

Excellent. Please let your classmates know about these free resources!

Lots of people seem to have problems with averaging. Don't make it hard. It's just like regular averaging. Example: @ ~20:00 0W for 1s, 3W for 2s, 12W for 2s, 3W for 2s, 0W for 2s, 3W for 2s, 12W for 2s, 3W for 2s, 0W for 1s over a time span of 16s is (0+3+3+12+12+3+3+0+0+3+3+12+12+3+3+0)/16 = 4.5W.

[@chandararanget7879]

Sorry, I still confuse ( 0+3+12+3+0+3+12+3+0)/16

[@mattdelaney584]

@@chandararanget7879 I was a little confused at first also. Where I got tripped up was not adding the Power (w) for the instantaneous (per sec.) I also believe Mr. Pytel missed a couple 12's in his response. 0+3+3+12+12+3+3+0+3+3+12+12+3+3+0 = 72. 72/16 seconds = 4.5

[@bigbadtech]

Good catch. I am indeed missing some 12s! I'm going to see if KZbin will let me edit the reply.

[@melissafoxx4271]

Or just use KISS method ;) (3*4 + 2*12) * 2 / 16 .... Nice and easy :)

[@luongle1996]

Dear sir! I'm mechanical engineering. I find alot book to learn electrical. But it very difficul to learn. lucky, i found all lecture series of you in youtube two months ago. I have learned electrical and hydraulic system on this lecture series. I will continous to learn from you. I shared all of that for my colleague and my friend. Thank you so much!

[@hamidmoradian5907]

Thank god ,finally someone really ,I mean really understand what is he taking about . And Thank you for thank you for this fantastic job.

[@bigbadtech]

Thanks for the kind words! Please let your friends know this resource is available.

[@konturgestalter]

please continue these great video lectures! Exactly what I needed.

[@TJGalloway1]

+Jim Pytel Thanks so much for getting to an AC circuit lecture series. I'm really grateful.

[@Sarcastix7]

Maybe YOU'RE too lazy to move your testing equipment but I move mine 50 times a second for proper readings. But seriously, these videos are fantastic. Thank you for making them

[@rick9833]

Outstanding explanation Jim. Many thanks!!

[@infinitx1330]

The lazy lab partner I can relate, fortunately the lab and the bachelors course is over, your lectures are helping me clear my backpapers, I've never understood the concepts as clearly as now, during anytime of the bachelor's course.

[@shvideo1]

Very clearly and comprehensively explained. Great content Thank you Jim. What's it with the lab partners?! They all seem to be dead beats! :)

[@jonathanswinsburg7716]

Great Video! There is an error at 11 min mark when 60 mA is calculated. Then when converted back to Amperes it is written as .6 in the equations that follow, but 60 ma= .06 A. Thanks again for making these lectures.

[@bigbadtech]

Good catch! Yes 60mA should be written .060A.

oh ho ho, it seems that i have struck gold here, thank you very much jim you can't imagine how much this has helped me, greeting from Egypt brother ❤️❤️❤️

@@bigbadtech i already did no need to say because this channel is too good to not share about it, btw thank you for taking the time to write "very nice" in arabic it really made my day, may allah bless you brother thank you again

[@bigbadtech]

Years ago I tried learning Arabic and all I remember was that and shkran! Those phrases served me well in Morocco.

[@abdullahahmed1673]

@@bigbadtech well, they should, we actually love it when any man takes time to even learn a few phrases in our language, you should come and visit Egypt man, if u ever happen to visit it, just find this comment and tell me here and iam going to show you around, of course iam not a guide but you can say that this would be a little price to pay for the information given on this channel, 2 hours ago i got an Email about an interview to a student activity here in my uni, they required me to have an understanding about signals, i typed that on youtube, and you suddenly popped up, once i saw that i felt truly blessed to have known you, and on behalf of everyone who watched your channel thank you very much jim, again, May allah watch over you, oh and btw u can learn french instead of arabic since its so much easier and go to algeria or morocco, they will understand you just fine, i think u know that already but i thought that i should mention it, thanks again

[@Heatseaker2011]

Absolutely brilliant

[@motloheloatsiame3595]

explanation outstanding and enjoyable. thanks

[@LazizbekYusupov92]

Hi, I have got an excellent idea, how could I teach my students and pass them from dc sections to ac. The best and smoothest movement I have ever seen. Going to use that in my practice.

Keep going your way!

Hii Respected Sir, Amazing lecture So happy to come across your channel May God bless U. If i may ask ... Which graphic tablet are you using in recording the lectures and which model is it..? Or do u recommend any nice graphic tablet i can use to write n record my lecture notes.? Another qn Sir ..which softwate are u using to write the notes on. Is it windows journal or ?

[@bigbadtech]

Glad you're making use of this material. I use MS OneNote on a Microsoft Surface. Record and edit with Camtasia.

[@mrashad219]

Thank you so much.

[@fahimstune3353]

Nice video

[@HARSHRAJ-j7v]

why do we need to find the average power why cant we use directly find the effective voltage or current i think it is because of two different values will come ex : 1 to 3 then 3 to 5

[@Alexmar345]

Minute 29:03 My answer is 38,1 and not 33,5 for the ave. power (106,7-26,7-3,8):2 = 38,1 What am I doing wrong?

[@bigbadtech]

Consider the 10ms time span of the whole waveform: Average power for the 10ms period is (3.8+26.7+106.7+26.7+3.8+3.8+26.7+106.7+26.7+3.8)/10=33.5.

[@Alexmar345]

Thanks! I was looking for DC RC/RL/RCL Circuit Analysis Videos on your channel but I can't find any. And also no videos for electric field or magnetic field or I just can't find them? All books are just crap to grasp the material. ^^

Check out the update I just published: kzbin.info/www/bejne/pnavoqqXhNxsmrM I'll be filling in the holes in the basic electronics series when I get back from summer holiday including transient DC analysis of capacitors and inductors. I've got some older material on magnetism as it relates to motors at: kzbin.info/www/bejne/nKeYZWxqobeEd9U
