In what form is the energy stored in a charged capacitor?
Correct answer: B. Electrical potential
- A. Gravitational
- B. Electrical potential
- C. Magnetic field
- D. Potential
Explanation
Energy is stored in a form of electrostatic field between plates of capacitor. This energy can be expressed in the form of work done by the battery.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
