  • #92
    The potential difference (``V_A - V_B``) between the points
    A and B in the given figure is :-

    (1) + 6 V
    (2) + 9 V
    (3) - 3 V
    (4) + 3 V
    digAnsr:   2
    Ans : (2)
    Sol. A
    2A
    2 1
    B
    3V
    VB = VA - (2 × 2) - 3 - (2 × 1)
    &implies;VA - VB = 9V
