What is physically happening here? this is a multiwire branch circuit with phases 180 degrees out of phase. As i've heard it explained, the "currents cancel" when they both travel on the neutral and it only carries the net difference. But what exactly is canceling? As I understand it current isn't actually (just) the movement of electrons, so it's not like equal electrons are moving both ways. Is it like the picture suggests and you have two different waves traveling independently and it just "looks" like they cancel on the neutral? do the waves "crash" and completely stop each other from continuing flow? is it just stationary EM fields that cancel where they meet? how are you able to derive power from these currents just "cancelling".
