Electric flux

Common symbols
ΦE
SI unitvolt-meter (V⋅m)
In SI base unitskg⋅m3⋅s−3⋅A−1
DimensionM L3 T−3 I−1

In electromagnetism, electric flux is the total electric field that crosses a given surface. The electric flux through a closed surface is directly proportional to the total charge contained within that surface.

The electric field E can exert a force on an electric charge at any point in space. The electric field is the gradient of the electric potential.
