Physics A level revision resource: Introduction to capacitors

Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference. A capacitor can take a shorter time than a battery to charge up and it can release all the energy very quickly.

Diodes and Diode Circuits

When the input voltage initially goes negative, the diode is forward-biased, allowing the capacitor to charge to near the peak of the input. Just after the negative peak, the diode is reverse-biased because the cathode is held near V p(in)-0.7 V by the charge on the capacitor. The capacitor can only discharge through the high resistance of R L ...
