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:

  1. Rotary potentiometers
  1. Concentric potentiometer
  1. Single-turn potentiometer
  1. Servo potentiometer
  1. Linear potentiometers
  1. Multi-turn slide potentiometers
  1. Slide potentiometers
  1. Dual-slide potentiometers
