![]() ![]() Gauss’s law states that the net electric flux through any hypothetical closed surface is equal to 1/ε 0 times the net electric charge within that closed surface. Gauss’s law involves the concept of electric flux, which refers to the electric field passing through a given area. When the electric field, because of its symmetry, is constant everywhere on that surface and perpendicular to it, the exact electric field can be found. In its integral form, Gauss’s law relates the charge enclosed by a closed surface (often called as Gaussian surface) to the total flux through that surface. As angle formed by different surface with respect to the electric field will be different therefore, for each surface electric flux will change.In electromagnetism, Gauss’s law, also known as Gauss’s flux theorem, relates the distribution of electric charge to the resulting electric field. Note − Flux for two or more surfaces cannot be calculated together at a time. dA → But in case of a closed cuboid flux linked is zero. So, Flux linked with a closed surface in an electric field is Φ E = ∮ E →. So, the total electric flux due to all the area will be given by the closed integral of all the electric flux linked with each surface. ![]() Similarly for surface (3) the angle between ( E → and A → is 0 o)įor surface (4) the angle between ( E → and A → is 90 o)įor surface (5) the angle between ( E → and A → is 90 o)įor surface (6) the angle between ( E → and A → is 90 o) If we take the surface (2) where the angle between ( E → and A → is 90 o) So the angle between ( E → and A → is 180 o) Since, the area vector is outside the area (1) and E → in opposite direction of the A →. If we take the Area (1), then the flux linked with it will be − Let, the cuboid be placed in an electric field, then the total flux linked with it will be calculated by adding the flux linked with each surface of the cuboid. In a closed surface the direction of A → is always be pointing normally outward the surface.Įach surface is given names (1,2,3,4,5,6) as shown in figure. All the surfaces are having a particular area and each area is having a particular direction. In this topic we will be experimenting using a cube which is closed and also has 6 plane surfaces.
