The S.I unit of capacitance of a capacitor is:
Correct answer: C. C: Farad
- A. A: Coulomb
- B. B: Volt
- C. C: Farad
- D. D: Ampere
Explanation
The S.I unit of capacitance is the Farad (F). This unit quantifies how much electric charge a capacitor can store per volt applied across its plates. One Farad is equivalent to one coulomb of charge stored per one volt of potential difference. The other options represent different electrical units: Coulomb measures charge, Volt measures potential difference, and Ampere measures current. None of these units relate directly to the ability of a capacitor to store charge, making Farad the correct choice.

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.
