Question

When a current is passed through a suspended moving coil

galvanometer, the deflection of the coil is arrested by……..

a) The elastic torsion of the suspension fibre

b) The elastic winding of the helical spring

c) The friction at the point of suspension

d) The changing magnetic flux through the coil.​

Answer 1

Answer:

b) The elastic winding of the helical spring

Explanation:

m not sure that it is true

Answer 2

d). When a current is passed through a suspended moving coil galvanometer, the deflection of the coil is arrested by the changing magnetic flux through the coil.

Galvanometer:

• A device which could detect current in circuit and also let us know the direction of current.
• In MCG or Moving coil galvanometer, the coil carrying current is rotated as there is change in magnetic flux which causes the deflection in the scale of moving coil galvanometer.

Therefore, when a current is passed through a suspended moving coil galvanometer, the deflection of the coil is arrested by the changing magnetic flux through the coil.
