( Electrical engineering : Semiconductor and electronic circuitry )
An FET is a transistor that uses an electric field to control the conductivity of a particular
channel in a semiconductor material.
With an FET, the output current flowing between the source and drain terminals is controlled
by a variable electric field applied to the gate terminal.
An FET is a transistor in which the voltage on one terminal creates a field that allows
or disallows conduction between the other two terminals.
