    When a potential is applied across the ends of a linear metallic conductor, then

    A)  the   free   electrons   are   accelerated continuously from the lower potential end to the higher potential end of the conductor

    B)  the   free   electron   are   accelerated continuously from the higher potential end to the lower potential end of the conductor

    C)  the free electrons acquire a constant drift velocity from the lower potential end to the higher potential end of the conductor

    D)  the free electrons are set in motion from their position of rest

    Correct Answer: C

    Solution :

    Current flows from high potential to low potential. \[\therefore \]The free electrons acquire a constant drift velocity from the lower potential end to the higher potential end of the conductor. (direction of electrons is opposite to that of current)
