Current through inductor is taken as a state variable why?
Interesting. Can you tell me more about the memory effect of an inductor?
In an inductor, the current can't change abruptly due to the property of inductance. The change in current creates a magnetic field, which in turn induces a voltage that opposes the change in the current, known as self-induced emf. This property of inductors makes the current through them a state variable.
