    In an ammeter 10% of main current is passing through the galvanometer. If the resistance of the galvanometer is C, then the shunt resistance, in ohms is:

    A)  9G

    B)  \[\frac{G}{9}\]

    C)  90G

    D)  \[\frac{G}{90}\]

    Correct Answer: B

    Solution :

    Shunt resistance \[S=\frac{{{I}_{g}}G}{I-{{I}_{g}}}\] \[=\frac{0.1G}{1-0.1}\]
