Hi everyone,

I'm a first yr electrical engineer. We have been covering 3 phase power supplies.

I understand true power and reactuve power but I am struggling to understand the relevance of

apparent power. This also means I don't understand power factor. I understand that apparent power is the vector sum of true and reactive power. I just don't understand what it really is.

I also would have thought that we would need a total power more than apparent power. That way we could work out what our total power supplied is and how much of that is true vs reactive and so on. I know I must be wrong about this. Can somebody please explain this shit to me?

Thanks

please accept this offering.
