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

Read the following paragraph and answer the questions that follow.
A p-type or n-type semiconductor can be converted into a p-n junction by doping it with suitable impurity. The motion of majority charge carriers causes diffusion current across the junction while the barrier electric field causes motion of minority carriers for drift current. In case of unbiased diode, the diffusion and drift currents are equal. This equilibrium is disturbed by the biasing batteries. Diodes, therefore, allow currents in one direction. This property of diode is used in making rectifiers.
