Under an external electric field electrons drift slowly inside the conductor.
1. The velocity of drift is
- 1 mm/s
- 105 m/s
- 3 × 108 m/s
- 3 × 109 m/s
2. What is meant by relaxation time?
3. Write an expression for drift velocity in terms of relaxation time.
4. When temperature increases what happens to drift velocity?
