### How do I determine the parameters for a battery equivalent model?

I have these pieces of information of a battery from which I want to estimate the battery equivalent RC parameters. Let it be first order or second order. I have a performance curve detailing battery ...

### 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 ...

### How to work out this implementation of chua's diode?

The author of a book claims that this is the implementation of Chua's diode by [Kennedy, 1992], although I cannot find this article. My question here is, how does this circuit work? For me, 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). ...
