How Does a Field Effect Transistor Work?

A transistor is a device in electronics that is used to switch or amplify signals. Transistors are composed of semiconductor material, which is a type of material that is not fully a conductor or an insulator, but has properties of both. Silicon is one very common type of semiconductor material. Transistors typically have three or more pairs of terminals that connect to an outside circuit. When current is applied to one pair of terminals, it alters the current that is going through one of the other pairs of terminals. A field effect transistor is a type of transistor that uses electrical fields to change the conductivity of channels that are located within a semiconductor material. Field effect transistors operate in a single-carrier fashion, and are often called uni-polar transistors for this reason. Field effect transistors have four separate terminals, all of which are named after their functions. The four terminals are known as the gate, the source, the drain and the body. The body
