Answer 2

Galvanometer:

A galvanometer is defined as a tool that's work to detect small current .

1. It also measure its magnitude.
2. The current and its intensity is indicated by a magnetic needle’s movement.
3. The coil in a very force field that's a crucial a part of a galvanometer.

Sensitivity of moving coil galvanometer:

It is defined because the current sensitivity of galvanometer is that the deflection which caused within the coil of the galvanometer per unit flow of electrical current through it.

$I = k n A B θ$

where ,

θ is that the angle of deflection ,

N is its turns,

A is area,

B is magnetic induction &

k is that the couple per unit twist.

The sensitivity of a galvanometer depends on:

1) Depend on n means number of turns

2). Depend B means intensity of force field.
