Key Characteristics of Equipotential Surfaces
- Constant Electric Potential On an equipotential floor, the electric capability stays the identical throughout. No work is performed while a price moves alongside the surface, because the ability electricity of the price does no longer change.
- Perpendicular to Electric Field Lines The Equipotential Surface Definition means that these surfaces are continually at proper angles to the electric subject lines. This shows that there is no factor of the electrical discipline parallel to the floor.
- No Work Done Moving a Charge Since there is no exchange in ability alongside the surface, no paintings is needed to transport a price from one point to any other on an equipotential surface. This is a key feature of those surfaces
- Equipotential Surfaces and Field Strength The closer the equipotential surfaces are to every other, the stronger the electric area in that place. This takes place because the electric area strength is related to the charge of alternate of potential with distance.
