Consider a circuit in which sinusoidal current i(t) of amplitude I, frequency f, and initial phase angle po flows; that is, i(t)-I.sin2 ft+фо). Derive an expression for the voltage vi(t) across an inductor of inductance L through which that current flows. Based on your derivation, how should inductor voltage amplitude Vi (i.e, the amplitude of the voltage across the inductor) vary with frequency? Describe the phase of the inductor voltage vi(t) relative to the current in the circuit
