po·ten·ti·om·e·ter

(pō-ten'shē-om'ĕ-tĕr),
1. An instrument used for measuring small differences in electrical potential.
2. An electrical resistor of fixed total resistance between two terminals, but with a third terminal attached to a slider that can make contact at any desired point along the resistance.
