A galvanometer of resistance `3663Omega` gives full scale deflection for a certain current `I_g`. The value of the resistance of the shunt which when joined to the galvanometer coil will result in `1//34` of the total current passing through the galvanometer is

A

`100Omega`

B

`200Omega`

C

`300Omega`

D

none of the above

Text Solution

Verified by Experts

The correct Answer is:
D
If I is the total current, then
`I_g=I//34`
or `I=34I_g`
Now, `S=(I_gG)/(I-I_g)=(I_gxx3663)/(34I_g-I_g)=111Omega`
