Energy stored in a parallel plate capacitor:
Correct answer: D. ½ CV^2
- A. CV
- B. CV^2
- C. ½ CV
- D. ½ CV^2
Explanation

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.
