What is the maximum energy that can be stored in a capacitor?
Correct answer: C. Depends on the maximum electric field
- A. Depends on the maximum area of the capacitor
- B. Depends on the maximum resistance offered
- C. Depends on the maximum electric field
- D. Depends on the maximum current passing through the capacitor
Explanation
The maximum energy that can be desirably stored in a capacitor depends on the maximum electric field that the dielectric can withstand without break down. Therefore, capacitor of the same type have about the same maximum energy density, i.e. joules of energy per cubic meter.

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.
