Question

What are the four types of potentiometers?

Answer 1

Potentiometer:

1. A potentiometer is a three-terminal resistor with a sliding or revolving contact that serves as a voltage divider that may be adjusted.
2. It functions as a variable resistor or rheostat when just two terminals are employed, one end and the wiper.

Types of potentiometer:

Potentiometers are classified into two categories based on wiper movement, which is then segmented into various types:

Rotary potentiometers:

1. This type of potentiometer comprises two terminal contacts between which a semi-circular pattern of uniform resistance is put.
2. A centre terminal on the gadget is likewise linked to the resistance through a sliding contact attached to a rotary knob.
3. The sliding contact on the semi-circular resistance may be moved by twisting the knob.
4. The voltage is measured across a resistance end contact and a sliding contact.
5. Rotary-type potentiometers are mostly utilized to provide variable supply voltage to a portion of electronic and electrical circuits.
6. The rotary potentiometer can be further classified as:
   1. Concentric potentiometer
   2. Single-turn potentiometer
   3. Servo potentiometer

Linear potentiometers:

1. A position sensor is a linear potentiometer.
2. They measure displacement along a single axis, either up and down or left and right.
3. Linear potentiometers are frequently rod-actuated and wire-connected.

1. The linear potentiometer is further classified as:
2. Multi-turn slide potentiometers
3. Slide potentiometers
4. Dual-slide potentiometers
