Why are the IV curves of capacitors and inductors ellipses?

I don't really know what the difference is between a regular diode, a zener diode, a schottky diode or an LED. Neither do I knoe the difference beetween a DIAC, a TRIAC or even a NPN transitor. The ...

Exponential nature of current growth/decay in inductors

Why are the curves for growth and decay of current in inductors of exponential nature i.e $$ 1-e^{-x} $$ and $$ e^{-x} $$ respectively. I understand the mathematical derivation for the current i(t). ...

What effect does resistance have on a diode's characteristics? (regarding IV curves)

I can't seem to find much information online regarding resistance values and diode behaviour. Am I right in saying that the IV curve of a diode is independent of any external resistance? For example ...
