Front

Voltage that causes current to flow through a circuit; the potential difference in charge between two points in a circuit (as in a cell or generator)

Back

Electromotive force

Front

The resistance of a circuit element (or circuit) that permits a steady current of one ampere to flow when a constant potential difference of one volt is applied to that circuit.

Back

Ohm

Front

A device for measuring temperature in which a pair of wires of dissimilar metals (such as copper and iron) are joined and the free ends of the wires are connected to an instrument (such as a voltmeter) that measures the difference in potential created at the junction of the two metals.
