JEE Main & Advanced Physics Current Electricity, Charging & Discharging Of Capacitors Question Bank Heating Effect of Current

  • 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,  [KCET 2004]

    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 :

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