    The resistance of a galvanometer is 90 ohms. If only 10 percent of the main current may flow through the galvanometer, in which way and of what value, a resistor is to be used                                  [MP PET 1996]

    A)                    10 ohms in series        

    B)            10 ohms in parallel

    C)                    810 ohms in series     

    D)            810 ohms in parallel

    Correct Answer: B

    Solution :

       Q \[{{i}_{g}}=10%\] of \[i=\frac{i}{10}\]Þ \[S=\frac{G}{(n-1)}=\frac{90}{(10-1)}=10\Omega \]
