4. Consider the RL circuit with a sinusoid voltage source shown in the diagram below. The values
of the resistor, inductor, input voltage amplitude and frequency are R = 5, L = 50mH,
and Vo = 10 V, respectively. The input voltage frequency w is variable. Assume that the
circuit has reached steady state.

The input voltage can be described using the complex sinusoid function
V(t) = Voejwt
The current is given by a sinusoid with same the frequency was the input voltage, but a
different magnitude and different phase. The physical voltage and current are obtained by
taking the real part. In complex form, the current is given by

The differential equation that describes the current follows from Kirchoff's voltage law, and
