Field-effect transistor

[feeld-i-fekt] /ˈfild ɪˌfɛkt/

noun, Electronics.
a transistor in which the output current is varied by varying the value of an electric field within a region of the device.
Abbreviation: FET.
a unipolar transistor consisting of three or more electrode regions, the source, one or more gates, and the drain. A current flowing in a channel between the highly doped source and drain is controlled by the electric field arising from a voltage applied between source and gate FET See also JFET, IGFET
