Sensitivity of galvanometer formula
WebThe sensitivity equals 𝜃 divided by 𝐼. Thus, for a galvanometer with a low sensitivity, the arm will deflect less for a given current. Likewise, for a greater sensitivity, it won’t take as much current to make the arm deflect more. Here, we know that when 𝐼 equals 360 microamps, 𝜃 …

WebThe sensitivity of a Moving Coil Galvanometer is defined as the ratio of the change in deflection of the galvanometer to the change in current. Therefore we write, Sensitivity = …
WebSensitivity of Wheatstone bridge. The sensitivity of a Wheatstone bridge is defined as the deflection in the galvanometer per unit current. In the unbalanced condition of the bridge, when current flows, it causes the pointer of galvanometer to get deflected. Thus, the deflection rate is the function of sensitivity. alia bhatt mehndi dressWeb30 Dec 2024 · The sensitivity of the tangent galvanometer is defined as the ratio of the change in deflection of the galvanometer to the current producing this deflection. Sensitivity = dθ / di A galvanometer is said to be sensitive if it gives larger deflection for a small current. Thus the sensitivity of tangent galvanometer can be increased by alia bhatt married dateWebAnswer. 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.
