Question

What are the conditions to be fulfilled for galvanometer to be used as ballistic galvanometer
?

Answer 1

Answer:

The conditions are : the moving coil must be wound on a metallic frame and eddy currents ... The oscillations of the coil die out instantaneously, the galvanometer is called dead beat galvanometer. When current is passed through a galvanometer, the coil oscillates about its mean position before it comes to rest.

Answer 2

Concept:

A galvanometer is a device used to gauge a weak electrical current or a function of the current by the movement of a coil.

Given:

A galvanometer.

Find:

The conditions need for the galvanometer to be used as a ballistics galvanometer.

Solution:

The conditions to be fulfilled for galvanometer to be used as ballistics galvanometer are:

The moving coil needs to be coiled on a metallic frame and there needs to be eddy currents for the galvanometer to be utilised as a ballistics galvanometer. The galvanometer is known as a dead beat galvanometer because the oscillations of the coil abruptly cease. A galvanometer's coil oscillates around its mean position when electricity is applied to it before coming to rest.

Hence, the galvanometer can be used as a ballistics galvanometer.
