What are the types of potentiometers?

A potentiometer is a three-terminal resistor with either rotating or sliding contact that forms an adjustable voltage divider. On the basis of the movement of the wiper, potentiometers are divided into two main types which are further classified as:

Rotary potentiometers

Concentric potentiometer

Single-turn potentiometer

Servo potentiometer

Linear potentiometers

Multi-turn slide potentiometers

Slide potentiometers

Dual-slide potentiometers
