WebThe sensitivity of a galvanometer is defined by 𝑆 = 𝜃 𝐼 and is measured in degrees per ampere ( ∘ / A ). The sensitivity of a galvanometer tells us how large a current is needed to cause a certain change in the angular deflection of the pointer. Galvanometers can only be used to measure very small current. Large currents can damage a galvanometer. WebPivoted coil galvanometer: A pivoted coil type galvanometer is mostly used in laboratory where a very sensitive galvanometer is not required.
