A potentiometer is an electronic component with many of the functions of a resistor – in fact, it is a variable resistor with a sliding contact forming an adjustable voltage divider. Control potentiometers are often used as volume controls in audio equipment. Rapid’s extensive range of control potentiometers includes rotary potentiometers, single turn pots, multiturn, slide and miniature potentiometers between power ratings 0.5W and 3W.
