Electric flux from a point charge
In electromagnetism, electric flux is the measure of the electric field through a given surface, although an electric field in itself cannot flow. 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 potential.

Gauss’ Law •The total electric flux (i.e. # of field lines) leaving a Gaussian (closed) surface is proportional to the charge enclosed by that surface. Gaussian Surface thomson webb \u0026 corfield cambridgeWebJan 15, 2024 · By Gauss’s Law, that means that the net charge inside the Gaussian surface is zero. The following diagram might make our conceptual statement of Gauss’s Law seem like plain old common sense to you: The closed surface has the shape of an egg shell. There are 32 electric field lines poking outward through the Gaussian surface (and zero … thomson webb and corfield cambridgeWebAnd the total flux through this closed surface is simply E times 4πR 2.Here we can cancel out 4πR 2, and we can notice that the total flux is equal to Q divided by E 0, where E 0 is permittivity of free space.. The flux doesn’t depend on the distance r. We would get the same result no matter the size of the closed surface around the point charge. thomson webb corfield cambridgeWebAn electric field is a vector field that describes the force that would be exerted on a charged particle at any given point in space.
