A galvanometer has resistance `G` and Current `I_(g)` produces full scale deflection. `S_(1)` is the value of the shunt which converts it into an ammeter of range `0-I` and `S_(2)` is the value of shunt for the range `0-2I`. The ratio of `S_(1)` and `S_(2)` is

A

`1/2 ( (I - I_g)/(2I -I_g) ) `

B

`(2I - I_g)/(I - I_g)`

C

`I//2`

D

`2`

Text Solution

Verified by Experts

The correct Answer is:
