Define Voltage sensitivity ?

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?

Define voltage senstivity mathematically.

Assertion current sensitivity of a galvanometer is directley proportionall to the current through the coil. Reason Voltage sensitivity is inversely proportional to voltage.

Assertion: current sensitivity of a galvanometer is directly proportional to the current through the coil. Reason: Voltage sensitivity is inversely proportional to voltage.
