A potentiometer is used for precise measurements of voltage, and sometimes current. It also can be used as a three-terminal potential (voltage) divider, which is a type of rheostat. Nearly every type of electronic instrument uses a potentiometer. The...

A measure of the oxidation/reduction status of a natural water, sediment or soil. It is a relative electrical potential, measured with a potentiometer (e.g., a pH meter adjusted to read in volts) using an inert platinum electrode and a reference...

A potentiometer is a variable tapped resistor that can be used as a voltage divider. A form of potentiometer is used as an instrument to measure the potential (or voltage) in a circuit by tapping off a fraction of a known voltage from a resistive slide...

A three-wire bus is commonly used to control digitally controlled potentiometers (DCPs). One example of this type of bus is Xicor's 32-tap X9315 (U3), shown in the figure. This asynchronous bus has no protocol and is popular in real-time and control applications. ...

Q I was under the impression that a rheostat has the exact same schematic symbol as a potentiometer and that both have the same wiper-over-the-fixed-resistor design. My understanding was that the rheostat simply could dump a ton more power than a pot (potentiometer)...
