- : an instrument for detecting the existence of small electric currents and determining their strength.
Examples
The mirror receiving instrument employed was the heavy prototype of the delicate reflecting galvanometer of Sir William Thomson.
The older or moving-magnet type of galvanometer is similar to the galvanoscope mentioned in Art. 239.
The moving-coil type of galvanometer (see Fig. 245) consists of a large magnet fastened to the frame of the device.
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.
The known resistances are changed until when on pressing the keys at E and K no current flows through the galvanometer.
