Question

Drift speed is defined as vd = Δl/Δt, where Δl is the distance drifted in a long time Δt. Why don't we define drift speed as the limit of Δl/Δt as Δt → 0?

Answer 1

Therefore, we can't describe drift speed or velocity as the limit of Δl / Δt as Δt → 0 because this is a short time period which is not sufficient to obtain the desired result.

Explanation:

• Under the impact of an existing electric field an electron drifts. An electron takes a very random direction in the process of the movement.
• So, we have a much more long time to take average. Therefore, we can't describe drift speed or velocity as the limit of Δl / Δt as Δt → 0 because this is a short time period which is not sufficient to obtain the desired result.
