What is the maximum energy that can be stored in a capacitor?
Correct answer: C. Depends on the maximum electric field the dielectric can withstand
- A. Depends on the maximum surface area of the capacitor plate
- B. Depends on the maximum resistance offered by the circuit
- C. Depends on the maximum electric field the dielectric can withstand
- D. Depends on the maximum current passing through the capacitor
Explanation
The energy stored in a capacitor is limited by the breakdown voltage of its dielectric material. This breakdown occurs when the electric field becomes too strong, a property known as dielectric strength.

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.
