What is the SI unit of capacitance?

• A. Farad
• B. Henry
• C. Volt
• D. Coulomb

Answer: (A)

Capacitance is the ability of a component to store electric charge for a given voltage. The fundamental relationship is C = Q / V, where C is capacitance, Q is the stored charge, and V is the potential difference. The SI unit for this quantity is the farad, defined as one coulomb of charge per one volt of potential difference. Because C equals Q divided by V, the unit is effectively coulombs per volt, which is the farad. In practice, you’ll see capacitances expressed in microfarads, nanofarads, or picofarads. The other units listed correspond to different electrical properties: volt is voltage, coulomb is charge, and henry is inductance.
