![]() Note : Electric flux is not affected by the charges outside the closed surface. The formula according to Gauss’s Law describing the electric flux over a surface S is given as:ĭS= Differential area of the given surface S. Here, E= The magnitude of the given electric fieldĭS= Surface area Electric Flux and the Gauss’s Law Electric Flux for a Non-Uniform Electric Fieldįor a given non-uniform field, the formula for the electric flux through a small surface area is as follows: Θ = The angle formed between the electric field lines and the normal to S. If the given electric field is uniform, then the electric flux passing through the surface will be:Į= The magnitude of the given electric field ![]() Electric Flux for a Uniform Electric Field The electric flux will be the rate of flow of the electric field of any given area and is also proportional to the electric field lines. The electric flux, being a scalar quantity, only has magnitude but no direction, and the unit of electric flux is Nm 2 /C ( Newton-meters squares per coulomb ). The famous Gauss’s law shows the mathematical relation between electric flux and enclosed charge. As the magnitude of positive electric flux is equal to the negative electric flux, the net electric flux will be zero. If every field line directed into the surface continues from the interior and directs towards the outward someplace else than the surface, there will be no net charge within the closed surface. Similarly, if the field lines are directed away from the closed surface, it will be positive. ![]() Moreover, the electric field lines directed on a closed surface will be negative. These field lines originate on the positive charge and end on the negative charge. It can also be thought of as the number of electric field lines intersecting at a given area. Electric flux is the measure of an electric field or it is the method of describing the electric field strength at a specific distance from the causative charge of the field.
