Give main characteristics of an equipotential surface

Give main characteristics of an equipotential surface.

The characteristics of an equipotential surface are:

  1. Potential remains the same at all the points on equipotential surface.
  2. No work is required to move a charge on an equipotential surface.
  3. No two equipotential surfaces can ever intersect each other.
  4. Electric field is always normal to the equipotential surface at every point.
  5. Equipotential surfaces are closer together in the regions of strong fields and farther apart in the region of weak fields.
