WebThe sensitivity of a galvanometer is higher if the instrument shows larger deflection for a small value of current. Sensitivity is of two types, namely current sensitivity and voltage sensitivity. Current Sensitivity ; The … WebThe sensitivity (i.e. current sensitivity) of a galvanometer is defined as the angle of deflection per unit current flowing through it. If dθ is change in the deflection produced by a small change in the current dI, sensitivity (S) of the galvanometer is given by. S = d θ d I. The current I flowing through a moving coil galvanomet er is given by.
