    Graphs between electric current and potential difference across two conductors? P and Q are plotted as shown in figure. We conclude from the graph that                     

    A) Resistance of P is grater than that of Q

    B) Resistance of P is less than that of Q

    C) Resistance of P is equal to the resistance of Q                          

    D) Nothing can be decided about the resistances of P and Q     

    Correct Answer: B

    Solution :

    [b] Resistance of a conductor = Slope of the graph between V and I Since, the slope of Q is more than the slope of P, the resistance of Q is more than the resistance of P.
