^Equipotential surfaces

Equipotential surfaces

1. An equipotential surface is an imaginary surface on which every point has one and the same value of electric potential. It can be curved or plane surfaces.
2. No work is done in moving any charge over an EPS.
3. Electric field is always ⊥ to EPS.
4. EPS tells us about direction of electric field.
5. EPS helps to distinguish regions of strong field from that of weak field. As the separation between two equipotential surfaces is more, where the field is weak & vice – versa.
6. No EPS can intersect each other.
