'The full-wave rectifier circuit shown in following Figure is t0 deliver 0.2 A and 12 V (peak values) to a load. The ripple voltage is to be limited to 0.25 V. The input signal is 120 V (rms) at 60 Hz. Assume diode cut-in voltages of 0.7 V. (a) Determine the required turns ratio the transformer: (b) Find the required value of the capacitor: (c) What is the PIV rating of the diode?'
