Answer: equipotential surface.
- A equipotential surface
- B electric current path
- C electric dipole
- D ideal insulator
Correct answer: A. equipotential surface
Explanation: All points on an equipotential surface share the same potential.
Field lines (radial) and equipotential lines (concentric circles) of a point charge. Equipotential surfaces are always perpendicular to the field lines. Image: Sjlegg, Public Domain, via Wikimedia Commons.
