Question
Describe schematically the equipotential surfaces corresponding to a uniform grid consisting of long equally spaced parallel charged wires in a plane.
Solution
The surfaces where the potential has a constant value are called equipotential surfaces.
Near the grid, the equipotential surfaces are of periodically varying shape which gradually reach the shape of planes parallel to the grid at a certain distance.
