Potentiometer

Potentiometer, often abbreviated as pot, are resistance components, whose resistance value is mechanically variable. This is done by sliding or rotating a contact.

A potentiometer has three terminals. If only two terminals are used, the potentiometer acts like a variable resistor. If all terminals are connected, it behaves as an adjustable voltage divider.

Nominal Resistance The nominal resistance of a potentiometer is the resistance value between the end terminals and is specified by the unit Ohm.

Known applications of potentiometers are as volume controls in audio systems or sensors in joysticks...
