Inductive Reactance - AC
Since the inductor limits a changing current (which an AC current is), it acts like a resistance. We call this action Reactance.
For an inductor, since VL = -L ?I/?t, VL will be big if L is big and/or if ? is big (causing ?I/?t to be big). A more detailed calculation for reactance (or resistance to an AC circuit) gives: XL = ?L and is used in the Ohm’s Law-like relation: VL = XLI
(the bigger XL, the smaller the I or the bigger the VL)
