Resistor trimmers generally come in the form of a potentiometer (pot), often called a trimpot.Potentiometers have three terminals, but can be used as a normal two-terminal resistor by joining the wiper to one of the other terminals, or just using two terminals.
The 'log pot', that is, a potentiometer has a resistance, taper, or, "curve" (or law) of a logarithmic (log) form, is used as the volume control in audio power amplifiers, where it is also called an "audio taper pot", because the amplitude response of the human ear is approximately logarithmic. It ensures that on a volume control marked 0 to 10 ...
Potentiometer – three-terminal variable resistor (variable voltage divider) [8] Trim pot – small potentiometer, usually for internal adjustments; Thermistor – thermally sensitive resistor whose prime function is to exhibit a large, predictable and precise change in electrical resistance when subjected to a corresponding change in body ...
While quite similar to normal potentiometers, digital potentiometers are constrained by current limit in the range of tens of milliamperes. Also, most digital potentiometers limit the voltage range on the two input terminals (of the resistor) to the digital supply range (e.g. 0–5 VDC), so additional circuitry may be required to replace a conventional potentiometer, (although digital ...
The "TRIMIT" potentiometer, one of the company's early innovations. Bourns, Inc. is an American electronics company that develops, manufactures and supplies electronic components for a variety of industries including automotive, industrial, instrumentation, medical electronics, consumer equipment and portable electronics.
A potentiometer being calibrated and then measuring an unknown voltage. R 1 is the resistance of the entire resistance wire. The arrow head represents the moving wiper.. In this circuit, the ends of a uniform resistance wire R 1 are connected to a regulated DC supply V S for use as a voltage divider.

Motorized potentiometers are used in industrial controls. [1] Motorized potentiometers may be used for remote control applications. [3] Motorized potentiometers can be used to build electrical/electronic analog computers. The motorized potentiometer can act as a computing element, but also as a way to convert a physical into an electrical value.
