For a given surface, the electric flux, PE, is proportional to the number of field lines through the surface. For a uniform electric field, the maximum electric flux is equal to the product of electric field at the surface and the surface area (i.e., EA).

Question
For a given surface, the electric flux, PE, is proportional to the number of field lines through
the surface. For a uniform electric field, the maximum electric flux is equal to the product of
electric field at the surface and the surface area (i.e., EA). The electric flux is defined to be
positive when the electric field E has a component in the same direction as the area vector A and
is negative when the electric field has a component in the direction opposite to the area vector.
C. Sketch vectors A and Ē such that the electric flux is:
Positive
Negative
Zero
