Current sensitivity of galvanometer
WebAnswer. The sensitivity of a galvanometer is defined as the constant of proportionality between the current in the coils and the angle of deflection of the arm, 𝜃 = 𝑆 𝐼. This rearranges to 𝑆 = 𝜃 𝐼. Here, we have 𝜃 = 3 3 ∘ and 𝐼 = 1 8 0 μ A. Therefore, 𝑆 = 𝜃 𝐼 = 3 … WebMar 20, 2024 · A galvanometer is a device used to detect the current and the current sensitivity shows the deflection when the current source is applied across the galvanometer. The S.I unit of the current sensitivity is radians per ampere. Complete answer: Firstly, learning about what a galvanometer is. A galvanometer is a device that …
