The source voltage for the power supply circuit is 230 V rms at 50 Hz. Calculate the following for a load resistance of 25 ohms and a smoothing capacitance of 1000 micro farads:
a). rms and peak voltage across the secondary winding of the transformer.
b). the peak voltage across the capacitor.
c). the peak to peak and rms ripple voltages.
d). the load d.c. voltage and current.
