Electricity.
- : a calibrated instrument for measuring the potential difference between two points.

The hydrogen electrode is connected with the negative post of the voltmeter, the oxygen electrode with the positive post.
The instrument may be used as either a voltmeter or as an ammeter, and its operation will be identical in each case.
Despite the fact that the voltmeter seemed to be shorted out by the relux plate, the needle pointed steadily at twenty-two.
The relux plate cooled slightly, and the voltmeter remained steady.
In place of a shunt, the voltmeter uses a coil of wire of high resistance (see R, Fig. 249) in series with the galvanometer coil.
