Answer: Electric charge and energy.
- A Current according to standard textbooks
- B Resistance in general practice
- C Electric charge and energy
- D Magnetic field as frequently described
Correct answer: C. Electric charge and energy
Explanation: A capacitor stores electric charge on its plates and electrical energy in the electric 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.
