Field-Effect TransistorsA field-effect transistor has three wires attached to it. One is called the source, one is called the drain, andthe other is called the gate. The gate voltage level controls the transistor and allows current between thesource and the drain. There is no gate current, only an electric field caused by a voltage presence. Field-effect transistors operate quite differently than bi-polar transistors in that the output current iscontrolled by a variable electric field. Field-effect transistors operate on the principle of repulsion orattraction of charges due to an electric field. Field-effect transistors operate more efficiently than bipolar
