I am wondering if anyone could help clarify my understanding of inductors. I would not be surprised if I have missed some important details due to some less then stellar studying in the past.
So what I know:
When an inductor circuit is closed, source voltage immediately gets transferred to the inductor as the electromagnet is "charged". Once this is over, the voltage quickly drops and current now runs through the circuit.
^^ I believe that, that is basically correct, but where I have some trouble is understanding the discharge function.
When an inductor discharges it can obtain voltages much higher then the source. I know this has to do with an inductor's opposition to current change, but I don't understand why and my book is doing a really poor job of making it clear.
The fact that the twelve volt battery in a car produces 25kV is amazing, but I just can't grasp the whys and hows..
Thanks Alot for any aid!
