A milliammeter of range of `10 mA` gives full-scale deflection for a current of `100 mA`, when a shunt of `0.1 Omega` is connected in parallel to it. The coil of the milliammeter has a resistance of.

A

`0.9 Omega`

B

`1 Omega`

C

`1.1 Omega`

D

`0.11 Omega

Text Solution

Verified by Experts

The correct Answer is:
A

`(i-i_g) S = i_g G`
`(100 - 10)(0.1) = 10 G rArr G = 0.9 Omega`.
