Define current senstivity of a moving coil galvanometer and state its S.I. units.

Give two factors by which the current sensitivity of a moving coil galvanometer can be increased.

What do you mean by current sensitivity of a moving coil galvanometer? On what factors does it depend?

How can current sensitivity of moving coil galvanometer be increased ?

What do you mean by current sensitivity of a moving coil galvanometer and how it can be increased ?

The current sensitivity of a moving coil galvanometer increases by 20% , when its resistance is increased by a factor of two. Calculate by what factor, the voltage sensitivity changes.

The sensitivity of a moving coil galvanometer increases with decrease is

To increase the current sensitivity of a moving coil galvanometer by 50%, its resistance is increased so that the new resistance becomes twice its initial resistance. By what factor does its voltage sensitivity change?
