220K ohm 16mm Rotary Pot Variable Potentiometer (Pack of 5)

This is a carbon track, single turn, adjustable resistances, of value 220KOhm Knob potentiometer. It is meant for mounting on panel and is supplied complete with a knob. The knob is affixed on the plastic spindle of the potentiometer and turns the spindle which changes the resistance. The variation of resistance is linearly proportion to the degree of rotation. Potentiometer, in electronic parlance, is a manually variable resistance. Because its most common consumer application is for controlling volume/tone of sound in broadcast receivers, it is loosely referred to as "volume" or ''tone''. It is not a meter with scale and needle. Potentiometers look different depending on size, power handled, application, value and type of material used. There is, however, a common feature-there is wiper which sweeps over a length of resistive material. The two ends of the resistive material as also the wiper are available to the user as electrical terminations. The user gets a variable resistance between the wiper and the two ends.

Also check pack of 5 16mm rotary potentiometers with a resistance of 1M ohms. These potentiometers have a tolerance of 20% and are used for adjusting various parameters like voltage and current in electronic circuits. The package includes 5 potentiometers, and each has a total rotational angle of 300° ± 5°.
