Question

Why damping correction is necessary in ballistic galvanometer?

Answer 1

Answer:

Hope this helps you bro

Explanation:

In actual practice the motion of the coil is damped by air resistance and induced current in the coil. The first throw of the galvanometer is, therefore, smaller than it would have been in the absence of damping. So it is necessary to apply a correction for damping to the first throw of the galvanometer

Answer 2

Explanation:

for correction

and for ur sensitivity of groins
