L> Equipotential LinesEquipotential lines

Equipotential currently are like contour currently on a map which map lines of equal altitude. In this instance the "altitude" is electric potential or voltage. Equipotential currently are always perpendicular come the electric field. In 3 dimensions, the lines kind equipotential surfaces. Activity along one equipotential surface requires no work because such motion is always perpendicular to the electrical field.

Equipotential lines: dipole

The electrical potential of a dipole display mirror symmetry around the center point of the dipole. Castle are everywhere perpendicular to the electric field lines.
