Gauss's law states that the net flux of an electric field through a closed surface is proportional to the enclosed electric charge. It relates the electric fields at points on a closed surface (known as a "Gaussian surface") and the net charge enclosed by that surface. The Gauss's law is one of the Maxwell law of electromagnetism and it relates to the electric fields at points on the Gaussian (closed) surface and the net charge enclosed by that surface. The flux of the electric field passing through a closed surface is defined as the product of the electric field passing through the area and the area of the surface in a plane perpendicular to the field. In other words, Gauss law is also defined as the total charge Q enclosed within a surface divided by dielectric constant.
