Question

On what factors, current sensitivity voltage sensitivity ofa galvanometer depend?​

Answer 1

That depends upon several factors

1. Number of turns of coil
2. Current flowing through the galvanometer
3. Torsion constant of suspension fibre
4. Strength of magnetic field
5. Restoring force.

Answer 2

it depends on numbers of turns coils area restoring force per unit twist and magnetic fields

hope it helps
