The transistor is the foundation of modern electronic devices. It is made entirely from semiconductor material (making it a solid state device) and can serve many different functions in a circuit including acting as a switch, amplifier, or current regulator. A transistor works by allowing a small amount of current applied at the base to control general current flow from collector to emitter through the transistor.
A solid state device has which of the following characteristics?
made entirely from semiconductor material |
|
made entirely from conductive material |
|
made entirely from insulative material |
|
made from a mix of conductive and insulative material |
