Hey, I don't if this is the right place to ask ( it is not a homework question but just a curious one about what i read in my textbook).. How can AC circuits even work? If the drift speed of an electron in a normal household wiring is something in the micro m/s and it reverse every 1/120 per second, how can it even get anywhere? Plus if the current is reversed and another one is induced by self induction, wouldn't it get in the way of the current too ( I mean if the Emf is in the opposite direction... ) so it would slow it down even more? AC currents kinda get me confuse :/ Edit: if you explain, try to keep it within my realm of understanding, I only have DC circuits and a bit of AC circuits understanding. I don't really understand the fact that all the expression of an RLC circuit are derived from one equation of induced emf... I can somewhat apply them but blindly.
