Question
When no current is passed through a conductor
Options
A.the free electrons do not move
B.the average speed of a free electron over a large period of time is zero
C.the average velocity of a free electron over a large period of time is zero
D.the average of the velocities of all the free electrons at an instant is zero
Solution
When no current is passed through a conductor the average velocity of a free electron over a large period of time is zero and the average of the velocities of all the free electrons at an instant is zero.
