Potentiometers, Variable Resistors

Devices that control the current that flows through a circuit.

Rotary Potentiometers - Linear Rotary Potentiometers - Linear A variable device that opposes the flow of current. The resistance of these devices is changed using a revolving stem that is attached to the central axis. The resistance varies equally as it is turned.
