A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum ...

The storage capacitor C 2 may be connected to the power supply terminals of a low-power device each time that its voltage and energy reach the required values. The direct discharge circuit used in this way needs only a simple control circuit, since it only needs a threshold-controlled switch.
The formula for this relationship is: E = 1/2 * Q^2 / C. Where: – E is the energy stored in the capacitor (in joules) – Q is the charge stored on the capacitor (in coulombs) – C is the capacitance of the capacitor (in farads) This formula is useful when the charge on the capacitor is known, rather than the voltage.
