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

1

D

2

Text Solution

Verified by Experts

The correct Answer is:
B
`S_1=((L_g)/(I-I_g))G and S_2=((I_g)/(2I-I_g))G`
`(S_1)/(S_2)=(2I-I)/(I-I_g)`
