AC Example-Complex Power

[yujustin]

very nice video and the only video i can find on youtube!! by the way for anyone confused about average Power=1/2V(I)(Pf), since Vrms is V/sqrt(2) and Irms is I/sqrt(2), u time them together u get 1/2V(I)(Pf)

I have been searching for something like this all day. This is a perfect example to study for my exam, thank you!

Thank you sir. You just prevented many tears and mental breakdowns on the verge of panic attacks. 🙏
Truly and amazing service to the struggling university community

You are a godsend. Thanks for the clear example, and useful insights!

Thank you very much for the instructional video. Have my test tomorrow. Wish me luck.

thank you son much I have an exam tomorrow and I didn't know what the complex power meant now I do

S=V(rms)I*(rms) but he is using PEAK values and must divide BOTH V and I* by the square root of 2. When multiplied that gives you S=1/2V(peak)I*(peak)

you a life saver thanks a lot sir everything is clear

i'm watching your videos with *2 speed :)

Reactive power is nothing but the power oscillations in the circuit due to inductors and capacitors present. It is really confusing when we are studying reactive power only with the phasor diagram, I have explained the concept with the help of fundamental waveforms. Also explained why reactive power compensation is necessary, how we can compensate.

Hi Darryl, is there any way you can do videos on second order RLC circuits?

[ridzfeels]

nice video..really helpful..thank u very much sir..

[Dpfpv]

isnt the equation for complex power S=VI* ?

[michaelmatheson]

Power factor needs more info. I think it needs a sign, like +ve or -ve? And "leading"or "lagging" ?

Hi Darryl, I read on your main site that you got from inspiration from Khan. Just wanted to say that I personally think you make much better content than him. I often find he goes off on tangents too often and doesn't cover advanced material very often. Good Job and keep it up :)

[sbonelobonengcongo]

any can help please sometimes when we calculating an apparent power we not introduce that halt sometimes we do eish im bit confused

[AArcher]

how can I convert those problems without using wolfram alpha??

[hithere]

Why is complex power equal to voltage times complex conjugate of current? Why is the current not taken as it is?

[MCShadesz]

How do you do the parallel calculation without using WA?

[jakosnopp]

In wich video do you define the complex power S?
