For the measuring instrument, see Potentiometer (measuring instrument) . A potentiometer /pÉµËtÉnÊiËÉmÉ¨tÉr/ , informally a pot, is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name.or the measuring instrument, see Potentiometer (measuring instrument) .
