Answer to Question #218288 in Electricity and Magnetism for Anita

Question

What happens when a steady potential difference is applied across the ends of a conducting wire?

(a) All electrons move with a constant velocity.

(b) All electrons move with a constant acceleration.

(c) The random electronic motion will, on the average, be equivalent to a constant velocity of each electron.

(d) The random electronic motion will, on the average, be equivalent to a nonzero constant acceleration of each electron.

Answer 1

Option (A) is correct option

(A)

All electron move with a constant velocity

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

As lower potential implise excess electrons and vice versa.
