Equipotential surfaces and field lines

Equipotential surfaces and field lines. Equipotential surfaces. Equipotential surfaces are mathematically speaking hypersurfaces. The potential in Cartesian coordinates is a function V=V( x,y,z ). With V( x,y,z )=const we define a 2D surface z=z( x,y ) in 3D space.
