3. (15%) Figure 2 shows a peak rectifier fed by a 100-Hz sinusoid having a peak value Vp = 120 V. The load resistance R = 20 kΩ. The output voltage shows a peal-to-peak ripple of 1.5V. Please calculate (1) the value of the capacitor C, (2) the fraction of the cycle during which the diode is conducting, (3) the average of the diode current. (5%, 5%, 5%)
