The resistance of the galvanometer G in ...


The resistance of the galvanometer G in the circuit's `25Omega`. The meter deflects full scale for a current of 10 mA. The meter behaves as an ammeter of three different ranges. The range `0-10` A, if the terminals O and P are taken, range `0-1A` between O and Q, range is `0-0.1` A between O and R. Then,

A

`R_(1)=0.25Omega`

B

`R_(2)=0.25Omega`

C

`R_(3)=2.5Omega`

D

`R_(1)=R_(2)=R_(3)`
