What is Electric Flux?
In this section, we will discuss the concept of electric flux, its calculation, and the analogy between the flux of an electric field and that of water . Let us imagine the flow of water with a velocity v in a pipe in a fixed direction, say to the right. If we take the cross-sectional plane of the pipe and consider a small unit area given by ds from that plane, the volumetric flow of the liquid crossing that plane normal to the flow can be given as vds. When the plane is not normal to the flow of the fluid but is inclined at an angle Ɵ, the total volume of liquid crossing the plane per unit time is given as vds .cos Ɵ. Here, ds cos Ɵ is the projected area in the plane perpendicular to the flow of the liquid.

What is electric flux?
Electric flux. In electromagnetism, electric flux is the measure of the electric field through a given surface, although an electric field in itself cannot flow. It is a way of describing the electric field strength at any distance from the charge causing the field. The electric field E can exert a force on an electric charge at any point in space.
What is the electric field of an electron?
An electric charge, such as a single electron in space, has an electric field surrounding it . In pictorial form, this electric field is shown as a dot, the charge, radiating "lines of flux". These are called Gauss lines. Note that field lines are a graphic illustration of field strength and direction and have no physical meaning.
Does Gauss' law apply to electric flux?
While the electric flux is not affected by charges that are not within the closed surface, the net electric field, E, in the Gauss' Law equation, can be affected by charges that lie outside the closed surface. While Gauss' Law holds for all situations, it is most useful for "by hand" calculations when high degrees of symmetry exist in the electric field. Examples include spherical and cylindrical symmetry.
