What Is current sensitivity? How it can be increased ?

A rectangular loop of area A and carrying a steady current I is placed in a uniform magnetic field:-Increasing the current sensitivity may not necessarily increase the voltage sensitivity of a galvanometer. Justify.

Name any two factors on which the current sensitivity of a galvanometer depends.

The current sensitivity of a moving coil galvanometer is 10 divisions/mA and voltage senstivity is 5 divisions/volt. Find the resistance of the galvanometer?
