A moving coil galvanometer allows a full scale current of `10^-4A` . A series resistance of `2mOmega` is required to convert the above galvanometer into voltmeter of range 0-5 V. Therefore, the value of shunt resistance required to convert the above galvanometer into an ammeter of range 0-10 mA is:

A

`0.4 Omega`

B

`0.3 Omega`

C

`1.2 Omega`

D

`0.1 Omega`

Text Solution

Verified by Experts

The correct Answer is:
D

`I_(g) =10/(100 + 10 xx 10^(3)) = 1 mA`
`I = 1A, S = (I_(g)/(I-I_(g)))G`
`= (10^(-3) xx 100)/(1- 10^(-3)) rArr S = 0.1 Omega`
