Question

What does 'electric flux' (ΦE) represent through a given area?
Options
A The speed of charges crossing the area.
B The total charge residing on the surface of the area.
C The total number of field lines crossing the area.
Correct Answer
D The force required to move a charge through the area.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Electric flux is a measure of the 'flow' of the electric field through an area, proportional to the number of field lines that pass through it.
