A moving coil galvanometer has a resistance of `990Omega.` in order to send only `10%` of the main currect through this galvanometer, the resistance of the required shunt is

A

`0.9 Omega`

B

`110 Omega`

C

`405 Omega`

D

`90 Omega`

Text Solution

Verified by Experts

The correct Answer is:

B

`l_(g)=0.1l,l_(s)=09l`
`S=(l_(g)G)/(l_(s))=01`
`lxx(990)/(09l)=110Omega`
