Editing Potentiometer (section)

==== Linear taper potentiometer ====
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 device where the resistance between the contact (wiper) and one end terminal is [[proportionality (mathematics)|proportional]] to the distance between them.

Precision potentiometers have an accurate relationship between resistance and slider position.
