Capacitor is a device used for:
Correct answer: A. Storing charge
- A. Storing charge
- B. Storing direct current
- C. Storing alternating current
- D. Storing voltage
Explanation
A capacitor is a device used for storing electric charge by creating an electric field between two conductive plates separated by an insulating material (dielectric).

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.
