What is a Potentiometer?

A potentiometer (or sometimes known as Pot) is a variable resistor. They come in a wide range of shapes and are used in various applications in your daily life.

How do they work?

Most potentiometer knobs are simply fixed on manually with a simple push by fitting it to the shaft. They either have a knob, screw, grub, or slider as a fixture that is used as a control element to vary the resistance between the middle terminal and either one of the outer terminals for the potentiometer.
