An infinite sheet of charge of constant surface density sigma coincides with the xy plane. what [otential for which E can be found. what are the equipotential surfacdes in this case?
For an infinitely large sheet of charge with current density σ, the electric field E everywhere except for points that lie in the x-y plane is given by:
E = σ/(2ε₀)
Any plane that is parallel to the x-y plane is an equipotential surface.
