Equipotential lines are lines or surfaces over which the electric potential is constant. They are perpendicular to electric field lines and help visualize the potential distribution in a field.
5 Must Know Facts For Your Next Test
Equipotential lines never intersect each other.
The electric field is always perpendicular to equipotential lines.
No work is required to move a charge along an equipotential line.
In a uniform electric field, equipotential lines are equally spaced parallel lines.
Equipotential surfaces can be three-dimensional, such as concentric spheres around a point charge.
