A) Field effect transistor
NJ2X Notes:
All FETs have gate, drain, and source terminals (three-terminal device) that are used to control current passing through the device. The electrical resistance between the source and the drain can be manipulated by changing the voltage between the gate and source. The FET is used in a wide variety of applications including amplifiers and power supplies.
