    In the circuit shown if \[{{R}_{1}}:{{R}_{2}}:{{R}_{3}}:{{R}_{4}}=1:2:3:4,\] then

    A) Ratio of current in \[{{R}_{2}}\] and \[{{R}_{3}}\] is \[3:1\]

    B) Ratio of current in \[{{R}_{1}}\] and \[{{R}_{3}}\] is \[3:1\]

    C) Ratio of current in \[{{R}_{1}}\] and \[{{R}_{2}}\] is \[4:5\] 

    D) Current in \[{{R}_{1}}\] is more than one in \[{{R}_{2}}\]

    Correct Answer: A

    Solution :

    [a] Current through  \[{{R}_{1}}=0\] Current through \[{{R}_{2}}=\frac{2}{{{R}_{2}}}\] Current through \[{{R}_{3}}=\frac{1}{{{R}_{3}}}\]
