To send 10% of the main current through a moving coil galvanometer of resistance `99omega`, the shunt required is –
A
`9.9 Omega`
B
`10 Omega`
C
`11 Omega`
D
`9 Omega`
Text Solution
Verified by Experts
The correct Answer is:
C
Required resistance which should be added in series so that , the current in the circuit is given by Initial resistance = Final resistane i.e., `G=((Gs)/(G+s))+R` `therefore R=G-((GS)/(G+S))=(G^2)/(G+S)`.
