Consider the circuit we built in the lab, only suppose the capacitor on the full-wave rectifier is 220μF, the Zener diode carries 20 mA, and the load carries 25 mA. Find the approximate ripple on the
capacitor. Now estimate the voltage ripple if we were to have used a half-wave rectifier. For a given capacitor, R , and Zener voltage, which will fail to regulate at a smaller load current:
A full-wave or half-wave rectifier? Explain. As the rectifier
voltage ripple increases, so does the ripple in the current out of the rectifier. Supposing the Zener remains in the breakdown state, does this current variation affect the load current? Explain.
