Field-effect transistor - Wikipedia

2019-4-23 · The field-effect transistor (FET) is an electronic device which uses an electric field to control the flow of current.FETs are 3-terminalled devices, having a source, gate, and drain terminal. FETs control the flow of current by the appliion of a voltage to the gate terminal, which in turn alters the conductivity between the drain and source terminals.
