a device designed to transmit electricity, heat, etc.

a device that produces electricity; may have several primary or secondary cells arranged in parallel or series

a cell containing an electrolyte in which an applied voltage causes a reaction to occur that would not occur otherwise (such as the breakdown of water into hydrogen and oxygen)

equipment that involves the controlled conduction of electrons (especially in a gas or vacuum or semiconductor)

electronic device consisting of a system of electrodes arranged in an evacuated glass or metal envelope

a positively charged electrode by which electrons leave an electrical device

(electronics) the part of a transistor that separates the emitter from the collector

a negatively charged electrode that is the source of electrons entering an electrical device

the electrode in a transistor through which a primary flow of carriers leaves the region between the electrodes

the electrode that is the source of electrons in a cathode-ray tube or electron microscope; consists of a cathode that emits a stream of electrons and the electrostatic or electromagnetic apparatus that focuses it
