Potentiometer This article is about the electrical component. For the measuring instrument, see Potentiometer (measuring instrument). Potentiometer A typical single-turn Potentiometer Type Passive Electronic symbol (International) (US) A Potentiometer /p t n i m t r/, informally a pot, is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.[1] 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.
A linear taper potentiometer (linear describes the electrical characteristic of the device, not the geometry of the resistive element) has a resistive element of constant cross-section, resulting in a ... Precision potentiometers have an accurate relationship between resistance and slider position.
