Inductor in a.c. circuit

Elize · February 27th, 2018, 09:19 AM

As it is written in my book and I saw on some videos about inductors in ac circuits if an inductor is connected with an a.c. source then the induced emf would be the same Voltage as the source that cause it but with opposite poles of the source which cause it why the induced should have opposite poles according to Lenz law when current increase the induced emf poles should be opposite of the source but when the current decrease the flux inside coil decrease so the emf want to stop this change so the emf would have the same poles as source and also if they have the same voltage but different poles shouldn't they cancel out?
