po·ten·ti·om·e·ter

 (pə-tĕn′shē-ŏm′ĭ-tər)
n.
1. A three-terminal resistor with a manually adjustable center connection that adjusts the resistance between the end terminals and the center, whose uses include controlling the volume of an amplifier. Also called pot3.
2. An instrument for measuring an unknown voltage by comparison to a standard voltage.


po·ten′ti·o·met′ric (-ə-mĕt′rĭk) adj.

potentiometer

(pəˌtɛnʃɪˈɒmɪtə)
n
1. (General Physics) an instrument for determining a potential difference or electromotive force by measuring the fraction of it that balances a standard electromotive force
2. (Electronics) a device with three terminals, two of which are connected to a resistance wire and the third to a brush moving along the wire, so that a variable potential can be tapped off: used in electronic circuits, esp as a volume control
Sometimes shortened to: pot
