At my work I have become involved with alternators and power systems and I was having a hard time understanding the concepts of VA and VAR. This video really helped, thank you.
7:47 you seem to imply that the charge involved in the computation of capacitance is the bulk of the electrons flowing inside the conductor. This is not the case: it is the (minute, almost negligible) amount of **surface** charge that matters.
I interpret "power frequency" as the same as the voltage and current frequency (50 Hz or 60 Hz), e.g. the system frequency. This is different to the frequency at which the instantaneous power oscillates but I'm not sure if this is common terminology elsewhere in the world.
@@VisualElectric_ You likely got the wording from "power line frequency", but in an educational context such as this video it's super confusing to be saying freq(x) = 2*freq(x). "Line frequency" would be confusing for students too as it's just industry jargon. 2:40 would have been a good spot to slow down and write out P=VI and show visually or algebraically why the frequency doubles.
OMG, I *feel* that this is best I can find on this topic, but still understand almost nothing. I mean I know formulas, and relations, but do not understand how all things work inside... 😩😩
so basically, real power is the power when the current and voltage is in phase. Reactive power is the power when they are not in phase. Apparent power is the power directly from the source. right?
Blown away by the quality of the video and animation. Thank you so much for explaining these topics!
Amount and Quality of detail provided in video is unparalleled 😮
Now! Finally I understand AC Circuit System. Thank you so much. Keep the Good Work.
GOD Bless Us:-))....

Thankyou very much for your time and dedication in providing this video..🙏❤
Your videos are really great! Thanks a lot for putting so much effort
Reactive Power is so hard to understand but it is there no doubt. Best explatation so far. Thanks
Not really hard. It's just the maximum rate of change of the energy oscillating between the source and load.
What an amazing presentation. The visuals are on point! I'm curious what software you use to make these?
Thanks!, I use After Effects for the animations.

Great explanation! What could possibly be the reason for such distorted current waveform at 8:52?
Excellent explain
Glad you liked it
2:40 can't be true. Not sure if you can throw a card up or something to say at twice the voltage and current frequency.

Brillant!
