Drift Velocity

Definition

The drift velocity is the average velocity of charged particles, such as electrons, in a conductor when an electric field is applied. It represents the net motion of charges due to the electric field.

Analogy

Imagine a crowded hallway where people are moving at different speeds. The drift velocity is like the average speed at which people are moving in one direction despite their individual speeds and directions.
