What is a potentiometer?

Expert Answer:

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.
