A rotary potentiometer (also known as a rotary panel or knob) is a type of adjustable resistor with a rotating contact that varies the resistance between two terminals. The resistance of a rotary potentiometer can be varied from a minimum to maximum defined value by rotating its potentiometer shaft. Rotary potentiometers are used in applications that require small adjustments of resistance such as precision variable divider, powered volume control, and data recording.

A rheostat is a variable resistor used to reduce the current or voltage in a circuit. It is a two-terminal passive electrical component with two sliding contacts on a resistive element. Rheostats are used to control the flow of current through a circuit, and the current through a rheostat varies as its resistance is varied. Examples of where they are used include power control, electric motor speed control, and audio power amplifiers.
