  • question_answer
    The plot represents the flow  of current through a wire at  three different times. The  ratio of charges flowing  through the wire at different  times is (see figure)

    A) 2 : 1 : 2            

    B) 1 : 3 : 3

    C) 1 : 1 : 1

    D) 2 : 3 : 4

    Correct Answer: C

    Solution :

    [c] Charge = area under the current-time graph \[{{q}_{1}}=2\times 1=2,{{q}_{2}}=1\times 2=2,\]and \[{{q}_{3}}=\frac{1}{2}\times 2\times 2=2\] \[{{q}_{1}}:{{q}_{2}}:{{q}_{3}}=2:2:2=1:1:1\]
