The half-wave rectifier with a freewheeling diode (Fig. 3-7a) has R4 and a
source with Vm50 V at 60 Hz. (a) Determine a value of L such that the amplitude
of the first ac current term in the Fourier series is less than 5 percent of the dc
current. (b) Verify your results with PSpice, and determine the peak-to-peak current.
