Potentiometer by means of construction can be divided into 2 groups
Potentiometer (or pot, as it is more commonly known) is a simple electro-mechanical transducer used as a voltage divider. It converts rotary or linear motion from the operator into a change of resistance, and this change is (or can be) used to control anything from the volume of a hi-fi system to the direction of a huge container ship as voltage or current regulators in electronic circuits. By means of construction, they can be divided into 2 groups: coated and wire-wound.
