Peak amplitude, zero average, and 1-kHz frequency. Assume that the diode has a 0.7-V drop when conducting. Let the load resistance R = 100 Ohm and the filter capacitor C = 100 mu F. Find the average dc output voltage, the time interval during which the diode conducts, the average diode current during conduction, and the maximum diode current
