what do you mean by current sensitivity of a moving coil galvanometer ?on what factors does it depends?

Current sensitivity of galvanometer is the deflection produced for a unit current flowing through it, A sensitive galvanometer should have a large deflection even for small amount of currents flowing through the circuit. Its value depends upon: The number of turns in the coil. The torsion constant of the suspension fibre of the coil.

Current Sensitivity Means The Number Of Deflections Produced by the Gavenometer When a Unit Current Passes Through it.

current sensitivity = (angle of deflection)/current

so it depends on angle of deflection as well as on the current passing through it.
