Potentiometer carbon track repair

Web27 Jan 2014 · Exercising the pot - turning from end to end and back, lots of times - can clean the track, but there might be holes in the track where the carbon has worn away. If so, then a new pot is the best answer. You may be able to approximately linearise the track by connecting a 50k resistor from the wipe to the top end.

WebA potentiometer is a manually adjustable variable resistor with 3 terminals. Two of the terminals are connected to the opposite ends of a resistive element, and the third terminal connects to a sliding contact, called a wiper, moving over the resistive element. The potentiometer essentially functions as a variable resistance divider.
