Work Step by Step
a. An equipotential surface is a set of points that all are at the same electric potential.
b. Equipotential lines (in 2 dimension) and surfaces (in 3 dimensions) are continuous.
c. The electric field is always perpendicular to an equipotential line/surface.
d. Electric field lines are always directed from higher equipotential lines/surfaces to lower ones.
e. Every part of a conductor is an equipotential surface/volume. In other words, all parts of a conductor, including the surface, are at the same electric potential.
f. It requires no work to move a charge from any point on an equipotential surface to any other point on the same equipotential surface.
g. Equipotential lines/surfaces cannot cross/intersect each other.
h. The places where equipotential lines/surfaces are closer to each other are locations of stronger electric field.
