1. No two equipotential surfaces or planes cut each other because then there would be two values of electric potential at the intersection point, which is not possible.

2. The surface of a conductor is always equipotential. Actually, the whole volume of a conductor is at equal potential.

3. Equipotential surfaces indicate regions of strong or weak electric fields. Using E = \(-\frac{d V}{d r}\) or dr = \(-\frac{d V}{E}\)
since dV (i.er potential difference) is constant on the equipotential surface, so dr ∝ \(\frac{1}{E}\)

4. If E is strong, dr will be small and the separation of equipotential surfaces will small than the electric field is strong. The separation between equipotential surface is large than the electric field is weak.
