How does the drift velocity Vd depend on the strength of the applied electric field?

1. Vd is directly proportional to E
2. Vd is inversely proportional to E
3. Vd remains constant
4. Vd is proportional to E squared

Correct answer: Vd is directly proportional to E

Solution

The drift velocity (Vd) of charge carriers in a conductor increases linearly with the strength of the applied electric field (E), meaning that as the electric field strength increases, the drift velocity also increases proportionally.
