This circuit component symbol represents a(n):
inductor |
|
transformer |
|
diode |
|
transistor |
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.
The diameter of a number 12 wire is __________ the diameter of a number 6 wire?
triple |
|
double |
|
less than |
|
more than |
The larger the number the smaller the diameter of the wire. So, the diameter of a number 12 wire is less than the diameter of a number 6 wire.
The electrical potential difference between two points is called:
current |
|
resistance |
|
voltage |
|
conductance |
Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.
A solid state device has which of the following characteristics?
made entirely from conductive material |
|
made entirely from semiconductor material |
|
made from a mix of conductive and insulative material |
|
made entirely from insulative material |
