A milliammeter of range `10 mA` has a coli of resistance `1 Omega`. To use it as an ammeter of range `1 A`, the required shunt must have a resistance of

A

`(1)/(101) Omega`

B

`(1)/(100) Omega`

C

`(1)/(99) Omega`

D

`(1)/(9) Omega`

Text Solution

Verified by Experts

The correct Answer is:
C

`S = (i_(g) G)/((I - i_(g))) = (0.01 xx1)/(1 - 0.01) = (1)/(99) Omega`
