- This video is a simple explanation of Power in AC systems. Why are there 3 different types of power? We use an intuitive approach to try to understand what Real, Reactive and Apparent power actually are. We first look at their fundamental mechanisms in isolation - first for real power, then for reactive power. After this, we define Power Factor. With this intuition, it is easier to understand the true nature of power.

Blown away by the quality of the video and animation. Thank you so much for explaining these topics!
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
Very good video!!!
Brillant!
Great explanation! What could possibly be the reason for such distorted current waveform at 8:52?
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.
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.
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.
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.
