Potentiometers, Rheostats, Trimpots, Presets are Variable Resistors. These are user interface devices. When a user turns a dial on a Panel it moves a wiper on a resistor film or wire-wound former. The variable resistors are also used to calibrate circuit sections on a board. These are used for either to obtain a precision or to offset errors due to circuit variations and decay of components on aging.
