Question

On which one of the factors does the sensitivity of a galvanometer depend is :

• A. Number of the turns of the coil
• B. The temperature of the room
• C. The current flowing in it
• D. The potential difference between the two ends

Answer 1

The correct option is A Number of the turns of the coil

A. number of the turns of the coil.

Current sensitivity of galvanometer,

$\frac{\varphi }{I}=\frac{NAB}{K}$

The sensitivity of a galvanometer depends on:

1). The value of n, i.e., number of turns

2). The value of B, i.e., intensity of magnetic field.
