    An electric fan and a heater are marked as 100 W, 220 V and 1000 W, 220 V respectively. The resistance of heater is     

    A) equal to that of fan        

    B) lesser than that of fan

    C) greater than that of fan

    D) zero

    Correct Answer: B

    Solution :

    [b] As \[R\propto {{V}^{2}}/P\] or \[R\propto 1/P,\] so resistance of heater is less than that of fan.
