Design a half-wave rectifier as a dc power supply that delivers 0.2A and 15V peak values to a load. The ripple voltage is to be no more than 0.4V peak to peak. The rectifier is led from the voltage line (120Vrms, 60Hz) through a transformer.
Calculate the standard potential for this cell at 25 °C. Standard reduction potentials can be found here.
