The relation between voltage and current for an inductor is given by:
v = L . di/dt
I think this relation is valid only in steady state periodic cyclic operation and provided that the circuit contains a resistive element.
My question now :Why a resistive element should be contained in the...
Any one knows about the 'RL Switching theorem',where a complicated RL switching circuit can be reduced to a single loop of resistance and inductance in series ?
i'm trying to use this theorem to find the circuit's time constant using step input function.
Any reference available?
Thanks for help
