They are not diodes, but the light emitting type of these devices produce electro-luminescent light. A dynamic RAM stores data on these devices and a Marx generator consists of several of them. A net torque was not observed on a suspended one of these devices in the Trouton-Nobel experiment. A method for keeping the power smooth involves adding the decoupling type of this device, and the smoothing out of voltage pulses produced by a rectifier is performed by the reservoir type. They consist of two conductors with opposite signs separated from each other by a dielectric, such as glass or mica, and an example of one is the Leyden jar. FTP name these circuit elements used to store electric charge, and whose characteristic property is measured in farads.
