WebTangent galvanometer is a device used for measuring current. It works on the principle of tangent law. A magnetic needle suspended at a point where there are two crossed fields at right angles to each other will come to rest in the direction of the resultant of the two fields. WebDec 30, 2024 · The principle, working and theory of pivoted type moving coil galvanometer is the same as suspended type moving coil galvanometer. Sensitivity of Moving Coil Galvanometer: The sensitivity of moving coil galvanometer is defined as the ratio of the change in deflection of the galvanometer to the change in the current. …
