Question

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

• 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

Answer 1

The correct option is C The free electrons acquire a constant drift velocity from the lower potential end to the higher potential end of the conductor

When a potential difference is applied across the ends of a linear metallic conductor the free electrons acquire a constant drift velocity from the lower potential end to the higher potential end of the conductor.

As Low potential implies excess electrons and vice versa.
