What is a potentiometer?
Asked by | 1st Feb, 2009, 06:22: PM
A potentiometer is a manually adjustable resistor. It is a three-terminal resistor with a sliding contact. If only two terminals are used (one side and the wiper), it acts as a variable resistor or Rheostat.
Potentiometers are commonly used to control electrical devices such as a volume control of a radio.
