Question

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

Answer 1

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.
