    In figure, the resistance of galvanometer G is 50 ohm and the battery is ideal. Of the following alternatives, in which case, are the currents arranged strictly in the order of decreasing magnitudes with the larger coming earlier-

    A) \[I,\text{ }{{I}_{1}},\text{ }{{I}_{g}},\,{{I}_{2}}\]

    B) \[I,\,{{I}_{g}},\,{{I}_{1}},\,{{I}_{2}}\]

    C) \[I,\,{{I}_{2}},\,{{I}_{1}},\,{{I}_{g}}\]

    D) \[{{I}_{g}},\text{ }{{I}_{1}},\text{ }{{\text{I}}_{2}},\,I\]

    Correct Answer: C

    Solution :

    [c] \[\frac{10}{100}=\frac{1}{10}\] \[\therefore {{i}_{g}}=0\] As \[I\propto \frac{1}{R}\] \[\therefore \text{ }{{\text{I}}_{2}}>{{I}_{1}}\] \[\therefore \text{ }I>{{I}_{2}}>{{I}_{1}}>{{I}_{g}}\]
