Answered by poonammudgil78

an instrument for measuring an electromotive force by balancing it against the potential difference produced by passing a known current through a known variable resistance.
a variable resistor with a third adjustable terminal. The potential at the third terminal can be adjusted to give any fraction of the potential across the ends of the resistor.
