1A current is passed through a parallel ...

1A current is passed through a parallel combination of `8Omega` resistance of galvanometer and `2Omega` resistance of shunt. Then current passing through shunt is _______

A

0.25 A

B

0.8 A

C

0.2 A

D

0.5 A

Text Solution

Verified by Experts

The correct Answer is:
B
I = 1A

We have,
`I_(S)=(I/(G+S))G`
`thereforeI_(S)=(1/(8+2))8`
`thereforeI_(S)=0.8A`
