Standard Books Physics Drift Velocity MCQ Question with Solution

For which of the following dependences of drift velocity vₐ on electric field E, is Ohm's law obeyed?

A

vₐ ∝ E

B

vₐ ∝ E²

C

vₐ ∝ √E

D

vₐ ∝ 1/E

Correct Answer

Option A

Detailed Explanation

Ohm's law is obeyed when the drift velocity is directly proportional to the electric field, which is represented by vₐ ∝ E.
