Question

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

Answer 1

Answer: (C)

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)
