The Inductor L which has zero initial charges at t = 0+ acts as a

### Right Answer is: A current source

#### SOLUTION

At t=0 when a circuit is at a steady state, an inductor acts as a short circuit. Thus at a steady-state at t=0 we replace all inductors with short circuits and capacitors by open circuits in the circuit.

At t = 0+ the inductor current cannot change in going from t=0 to t = 0+, we replace the inductors with current sources whose values are the currents at t=0.
