MCQ
When no current is passed through a conductor:
  1. The free electrons do not move.
  2. The average speed of a free electron over a large period of time is zero.
  3. The average velocity of a free electron over a large period of time is zero.
  4. The average of the velocities of all the free electrons at an instant is zero.
  • A
    Only $A$
  • B
    $A$ and $B$
  • C
    $B$ and $C$
  • ✓
    $C$ and $D$
✓

Answer

Correct option: D.
$C$ and $D$
No current is passed through a conductor means. That the average velocity of a free elecron over a large period of time is zero or the average of the velocity of all the free electrons at an instant is zero.
