Question

Relation between the drift velocity and an electric field is ----?

• A. \( v_d = \frac{E}{\mu} \)
• B. \( v_d = E \times \mu \)
• C. \( v_d = \frac{\mu}{E} \)
• D. \( v_d = \mu \times E^2 \)

Hint:

Drift velocity is related to the electric field and the mobility of the charge carriers in the conductor.

Answer 1

The Correct Option is A

The drift velocity \( v_d \) is the average velocity of free electrons in a conductor under the influence of an electric field \( E \). The relation between drift velocity and the electric field is given by: \[ v_d = \frac{E}{\mu} \] Where: - \( E \) is the electric field, - \( \mu \) is the mobility of the electrons. This relationship shows that the drift velocity is directly proportional to the electric field and inversely proportional to the electron mobility.
