Moreover, it doesn't matter where you keep the charge inside the closed surface, the number of field lines passing through the surface would be the same. ![]() If the same amount of charge produces the same number of field lines, the electric flux through any closed surface (that includes the charge) must be the same. The flux is influenced by the charges present around. The relation between electric flux and electric field intensity is $E=\varepsilon D$. If the vectors are along the same direction, the flux is positive but when the vectors are opposite to each other, the flux is negative. Mathematically, it is the dot product of the electric field vector and the area vector. Įlectric flux is a measure of the number of electric field lines passing through a given area of cross-section. The units of electric flux density are C/m 2 and the dimensional formula is M 1 L 3 I -1 T -3. The electric flux density vector has the same direction as the electric field intensity. In the above case the area vector will be $\overrightarrow$ Since the direction of the area vector of the cross-product vector is mutually perpendicular to the two vectors, the area vector is perpendicular to the sides of the cross-sectional plane. This is the reason why the area is a vector quantity. Now, the formula of the area is a cross-product between two vectors that describe the adjacent sides of the figure. Let the plane be a square and have side ‘s’. Its magnitude is the value of the area of the cross-section and its direction is perpendicular to the cross-sectional plane.Ĭonsider a finite flat plate or a finite plane, in 3-D space, oriented in any manner. The area vector describes the vector which is perpendicular to the plane of the area of the cross-section. Electric flux is the cross-product of the electric field vector and the area vector. ![]() ![]() These are the vector field lines that describe the acceleration vector at a particular point.Īccording to the electric flux notes PDF, electric flux is the measure of the number of electric field lines passing through a given area of cross-section. The electric field has electric field lines. This is analogous to the gravitational field or magnetic field. An electric field is a region around a charged object or a charged particle within which the effect of electric force is present. ![]()
