write the factors which current sensitivity of galvanometer depends ?
The current sensitivity depends on
1) Inversely to Torsion Constant that depends in the nature of substance used which is usually some phosphor bronze alloy ( k or alpha depending on the textbook you use)
2) Directly to the number of turns which is analogous to the proportional(N)
3) Directly to the area of the coil (A)
4) Directly to the magnetic field (B)
