This flow of liquid, which is given by the quantity v dS, is called flux.
v = velocity of liquid (calculated as the rate of change of length per unit time).dS = surface area perpendicular to the velocity v of water.Electric Flux can also be described as the product of the electric field and surface area projected in a direction perpendicular to the electric field.Įlectric Flux Explanation of Electric FluxĪssume a liquid flowing with velocity ‘v’, over a very small surface dS, in normal direction with respect to the surface. The rate of flow of water is calculated as volume passing through the given area per unit time which is v dS.ĭifferentiating the given relation with respect to time, we have: (d Volume/ d t) = dS × (d length/ d t) It is an additional physical quantity that is used to measure the strength of an electric field and build the fundamentals of electrostatics in the world of Physics.
In Electrostatics, Electric Flux is described as several electric field lines, passing per unit area.
