By connecting shunt of `12Omega` resistance, the deflection of galvanometer decreases to 10 marks from 50 marks, then the resistance of galvanometer is _____

A

`24Omega`

B

`12Omega`

C

`6Omega`

D

`48Omega`

Text Solution

Verified by Experts

The correct Answer is:
D

`n=50/10=5&s=G/(n-1)" "thereforeG=s(n-1)`
= 12(5 - 1)
`thereforeG=48Omega`
