Question

The load is a 100 resistor. The transformer provides an RMS output at 50 Hz of • VAC = (10 + A + B + C + D + E) V = The final 'V' is the unit of volts. Neglect voltage drop in the diode. For how long (in milliseconds) does the capacitor supply current to the load if the diode conduction angle is 20°? Calculate the average (dc) current (in milliamperes) through the load assuming that the value of the filter capacitor is very large. What is the average power (in watts) dissipated in the load? What value of capacitor (in microfarads) is required to give a peak to peak ripple voltage of 1.00 V? Without the capacitor filter, what is the RMS value of the voltage across the load
