An opposition to current flow that occurs in alternating current circuits is called?

Question

ljetibo · Answer

Lenz law describes how an induced current will always have the opposite direction the the emf of the circuit. However, if there is no induction, or self-induction even, in the circuit this current will never appear. 

In ideal circuits this is the case, in realistic circuits there is always some self-induction at least. Maybe that answers your question?

I believe the term that is asked for is "impedance."  This the opposition offered to AC (alternating current) which includes both resistance and reactance.

Ah, sry to be the one to give the wrong answer here, but ignore mine, I should've deleted it. Impedance is the correct answer.
