What is a potentiometer?


A potentiometer is a variable resistor which increases or decreases the resistance in an application. Usually available as either digital or analogue, there are two main types of potentiometers, rotary and linear.

• Linear - comes in a rectangle strip shape and can be pulled up or down for the required resistance, Used a lot within sound systems for mic output or volume control.

• Rotary - the shaft is housed by a knob, you would find these on dimmer switches or speakers, turning (usually to the right) will increase the resistance amplifying the output, whether that is light, sound or voltage.

How do potentiometers work?


Used in various applications, potentiometers operate as a resistor for electronic devices. As an example, a dimmer switch you would find in place of a light switch would house a potentiometer. Whichever direction it is turned, either increases or decreases the resistance, manipulating the light output from the bulb. Another common use would be speaker or sound systems, operating as a volume switch. There are various types of element material, usually as rotary or linear, such as:

• Wire-wound

• Conductive

• Plastic

• Carbon

• Cermet
