The essential usefulness of a transistor comes from its ability to use a small signal applied between one pair of its terminals to control a much larger signal at another pair of terminals. This property is called a gain. The transistor can control its output in proportion to the input signal, that is, it can act as an amplifier. Transistor also can be used to turn current on or off in a circuit like an electrically controlled switch, where the amount of current is determined by other circuit elements.
