5) Consider a circuit in which sinusoidal current i(t) of amplitude I, frequency f, and initial phase angle 0 flows; that is, i(t)  I sin(2ft  0 ) . Derive an expression for the voltage vL(t) across an inductor of inductance L through which that current flows. Based on your derivation, how should inductor voltage amplitude VL (i. e., the amplitude of the voltage across the inductor) vary with frequency? Describe the phase of the inductor voltage vL(t) relative to the current in the circuit.
