$(a)$ a constant electric field in the $z-$direction,

$(c)$ a single positive charge at the origin, and
$(d)$ a uniform grid consisting of long equally spaced parallel charged wires in a plane

$(a)$ Equidistant planes parallel to the $x -y$ plane are the equipotential surfaces.
$(b)$ Planes parallel to the $x -y$ plane are the equipotential surfaces with the exception that when the planes get closer, the field increases.
$(c)$ Concentric spheres centered at the origin are equipotential surfaces.
$(d)$ A periodically varying shape near the given grid is the equipotential surface. This shape gradually reaches the shape of planes parallel to the grid at a larger distance.
