Answer: charge and energy.
- A charge and energy
- B only some mass
- C only some current
- D only some sound
Correct answer: A. charge and energy
Explanation: A capacitor stores charge on its plates and energy in the field between them.
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.
Concept context
Electric potential, equipotential surfaces, potential energy of charge systems, conductors, dielectrics, capacitors, combinations, and energy storage.
