Give main characteristics of an equipotential surface.
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.
- Electric field is always normal to the equipotential surface at every point.
- Equipotential surfaces are closer together in the regions of strong fields and farther apart in the region of weak fields.
