Answer:
Current sensitivity of a galvanometer is defined as the deflection produced in the galvanometer when a unit current flows through it. Where n is no of turns in the coil of galvanometer, B is Magnetic field around.
The sensitivity (i.e. current sensitivity) of a galvanometer is defined as the angle of deflection per unit current flowing through it. `I=k/(nAB)theta` where θ is the angle of deflection , N is its turns, A is area, B is magnetic induction & k is the couple per unit twist.
