The galvanometer shown in the figure reads 3A, while the ideal voltmeter reads 24 volt. The value of `R = 7 Omega`. The galvanometer resistance is :

A

`10 Omega`

B

`5 Omega`

C

`1 Omega`

D

`20 Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
`V = i(G+R)`
or `24 = 3 sqrt(G+7)`
or `G = 1 Omega`
