what is the SI unit of current sensitivity in moving coil galvanometer?

Current sensitivity of a galvanometer is defined as the deflection produced in the the galvanometer when a unit current flow through it.
The S.I unit of current sensitivity is radA‚Äč-1 .

Current sensitivity is the deflection produced for unit current in a moving coil galvanometer. It can be represented as Si.

Si = Phi/i where phi is the deflection produced and i is the current flowing through the galvanometer.

Si unit is divisions per ampere [ ie div/A].

Hope that helps.
