Inductor not same with resistance. For resistance, there is obstacle flow electron,(with voltage drop, proportionable with current).For inductor,oppose the current change. In accordance with the Lenz Law, voltage of inductance always like polarity, to try to keep the current remains constan. That means, if current increase, voltage induction will “encourage” electron currnet. If current decrease, polarity will restore and encourage electron flow to reduce barriers.Flow resistance change methode is called reactance, it’s better than principle work the resistance.
