Definition of Capacitance. Capacitance is a measure of a non-conducting material''s ability to store energy by creating a separation of charge across a potential difference (voltage). The material must be non-conducting, like glass or a PVC pipe, because otherwise the charges would flow through it, unable to stay separated.
As illustrated in Fig. 2 d, the capacitor is first charged by external bias to a given electric field strength, and then, via high-speed and high-voltage switches (e.g., vacuum switch), the stored energy of the capacitor is released by a load resistor (R L) that is connected to it in series.
