What is the term for energy that is stored in an electromagnetic or electrostatic field?
- A Kinetic energy
- B Ampere-joules
- C Joule-coulombs
- D Potential energy
Correct answer: D — Potential energy. From the official ISED question bank, verified word for word.
Why
Potential energy is the correct term because it describes energy held in readiness within a field, much like a stretched spring or a raised weight, waiting to be released. The full explanation — and one for every question — is in Pro.
