  • question_answer
    Two electric bulbs A and B are rated as 60 W and 100 W. They are connected in parallel to the same source. Then,

    A)  Both draw the same current

    B)  A draws more current than B

    C)  B draws more current than A

    D)  Current drawn are in the ratio of their resistances

    Correct Answer: C

    Solution :

    [c] \[i\propto \frac{1}{R}\] and \[P\propto \frac{1}{R}\Rightarrow i\propto P\]i.e., in parallel bulb of higher power will draw more current.
