Question

The current is zero in a conductor when no potential difference is applied because:
Options
A the electrons are not moving
B the electrons are not moving fast enough
C for every electron with a given velocity there is another with a velocity of equal magnitude and opposite direction.
Correct Answer
D equal numbers of electrons and protons are moving together
Correct Answer

Option C is the correct answer.

Detailed Explanation

At equilibrium, random thermal motion cancels out; no net drift velocity → no net current.

Hint

Net velocity = 0.
