Can someone explain a little of the physics behind 'phases' I can't get a grasp on what is actually happening. Current - I can understand that electrons are moving. Voltage - okay, no problem different charge here than over there. But then you throw in phases...and stuff is cancelling out.....where did it go? I can do the math, that's not the problem, but I must have missed the lecture day when the broke it all down. Thanks in advance.
