Electric flux is a property of an electric field that may be thought of as the number of electric lines of force that intersect a given area.

The significance of the flux coming out of a closed surface is that it tells you the net charge inside that surface.

**Formula to calculate total electric flux.**

The permittivity of free space is a physical constant equal to approximately 8.85 x 10^12 farad per meter.

**Example:**

Suppose the enclosed charge in an area is 14 coulomb, calculate the electric flux.

Therefore, the electric flux is 1.58^-12 volt meters.
