When a galvanometer is shunted with a 4 ...

When a galvanometer is shunted with a `4 Omega` resistance, the deflection is reduced to one-fifth. If the galvanometer is further shunted with a `2 Omega` wire, determine current in galvanometer now if initially current in galvanometer is `I_(0)` (given main current remains same).

A

`I_(0)/(13)`

B

`I_(0)/B`

C

`I_(0)/8`

D

`(15I_(0))/(13)`
