I've been studying circuits for almost 3 months now, and I can pretty much carry out analysis of circuits with inductors. I know the basic relationships for an R-L circuit etc, how to derive the equations and so on. In other words, I can solve textbook problems. But what does an inductor actually do? You see, for resistors, one can rather easily attain a visceral appreciation of its effects. I find it hard to 'picture' an inductor at work. The textbooks I've read are all really abstract; storing 'magnetic fields' and 'back emfs'. One I read even attempted drawing a comparison with fluid flow; how an inductor acts as a dam for energy because of the back-emf... I don't get it tho. Could someone please explain the function of an inductor in as lay a manner as possible? Like for what reasons would a person want to include an inductor in a circuit.
