Separating two electrically conductive plates with an insulator forms a device called a capacitor. Among the many traditional uses of capacitors in experimental science are the storage or collection of charges, the blocking of DC currents, filtering electronic signals, and the generation of voltage ramps and timing. Devices with very large capacitance values are often used to store electrical power as memory backup or provide rapidly delivered high-voltage power pulses for “photo flash” bright-light ...
