Define voltage sensitivity of a MCG.

What is the basci principle of a moving coil galvanometer? Derive an expression for current flowing through the galvanometer in terms of steady angular deflection of its coil. Define voltage. Sensitivity of the galvanometer. What is a convenient way to increase its sensitivity?

IF the current sensitvity gets doubled then what happens to the voltage sensitivity of the MCG?
