Type: MCQ-conceptual-Medium-Class 12
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.
