po·ten·ti·om·e·ter

(pə-tĕn′shē-ŏm′ĭ-tər)

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.

[potenti(al) + -meter.]

po·ten′ti·o·met′ric (-ə-mĕt′rĭk) adj.

potentiometer

(pəˌtɛnʃɪˈɒmɪtə)

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

poˌtentiˈometry n

po•ten•ti•om•e•ter

(pəˌtɛn ʃiˈɒm ɪ tər)

n.

1. a device for measuring electromotive force or potential difference by comparison with a known voltage.

2. voltage divider.
