What is the basic unit of capacitance?

• A. Ohm
• B. Farad
• C. Henry
• D. Siemens

Answer: (B)

Capacitance is a measure of how much electric charge a capacitor can store for a given voltage. The unit used for that amount is the farad, which is defined as one coulomb of charge per one volt of potential difference (C = Q/V). Because one farad is a large value, practical capacitors are often rated in microfarads or nanofarads. Other common electrical units correspond to different quantities—ohms for resistance, henries for inductance, and siemens for conductance—so the farad is the term that uniquely describes capacitance.
