Question

What is an equipotential surface? Mention any two characteristics of equipotential surfaces.

Answer 1

The characteristics of an equipotential surface are: Potential remains the same at all the points on equipotential surface. No work is required to move a charge on an equipotential surface. No two equipotential surfaces can ever intersect each other.

1.Equipotential surfaces never cross each other.
2. Equipotential surfaces give the direction of the electric field.
3. Electric field is normal to the equipotential surfaces.
4. Equipotential surfaces help us to distinguish the region of strong field from that of weak field.
5. Work done in moving a test charge over an equipotential surface is zero.
