We will consider a flat surface of area A and an electric field which is constant (that is has the same vector value) over the surface The surface is
Is electric field constant everywhere?
There are very few cases where electric field is uniform in all point in space . When there are no charges , electric field is zero at all points and hence it is uniform. Electric field due to a infinite plane with uniform charge distribution is also uniform at all points.
The flux Φ of the electric field →E through any closed surface S (a Gaussian surface) is equal to the net charge enclosed (qenc) divided by the permittivity of free space (ϵ0): Φ=∮S→E⋅ˆndA=qencϵ0. To use Gauss's law effectively, you must have a clear understanding of what each term in the equation represents.
What is a constant electric field?
A constant electric field is one whose (partial) derivative with respect to time is zero. That is, it does not change in time. A uniform electric field is one whose (partial) derivative with respect to any spatial variable is zero. That is, the field is the same in magnitude and direction throughout space.
What is the electric field on the surface?
The Electric Field at the Surface of a Conductor. If the electric field had a component parallel to the surface of a conductor, free charges on the surface would move, a situation contrary to the assumption of electrostatic equilibrium. Therefore, the electric field is always perpendicular to the surface of a conductor
