An alternating voltage E=E0 sin omegat i...

An alternating voltage `E=E_0 sin omegat` is applied to a circuit containing a resistor R connected in series with a black box. The current in the circuit is found to be `I = I_0 sin(omegat+pi/4)`.

State whether the element in the black box is a capacitor or indutor.
