When a potential difference is applied across the ends of a linear metallic conductor [MP PET 1997]

• A.                    The free electrons are accelerated continuously from the lower potential end to the higher potential end of the conductor
• B.                    The free electrons 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
