Question

In an AC circuit, voltage V =  V₀ sinωt and inductor L is connected across the circuit. Then the instantaneous power will be

Answer 1

Correct option (c)

Explanation:

If dI/dt is rate of change of current  through inductor L of any instant, then induced emf in the inductor of the same instant is

To maintain the flow of current in the circuit applied voltage must be equal and opposite to the induced voltage.
