Question:
Drift speed \( v \) varies with the intensity of the electric field \( E \) as per the relation
Drift speed \( v \) varies with the intensity of the electric field \( E \) as per the relation
Show Hint
Drift speed is directly proportional to the applied electric field in a conductor.
Updated On: Mar 19, 2025
- \( v \propto E \)
- \( v \propto \frac{1}{E} \)
- \( v \propto E^2 \)
- \( v \propto E^{-2} \)
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Drift velocity is given by:
\[
v_d = \mu E
\]
where \( \mu \) is mobility. Clearly,
\[
v_d \propto E
\]
Thus, the correct answer is \( v \propto E \).
