Gauss and Weber's mirror galvanometer (Gottingen; 1833). 1897. A galvanometer is an electromechanical instrument for detecting and measuring electric current. The most common use of galvanometers was as analog measuring instruments; called ammeters; used to measure the direct current (flow of electric charge) through an electric circuit.

This result can obviously be referred only to the fact that the galvanometer circuit was closed in Gotch's experiments for a very short time after the moment of stimulation, while in du Bois-Eeymond's method, not merely the exciting current, but also the whole after-current of the preparation, passes through the galvanometer. In the first case, therefore, the homodromous after-current (positive polarisation, in du Bois-Eeymond's sense) can add nothing to the homodromous induction-shock which pr
