What is the basic unit of capacitance?

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

Answer: (A)

Capacitance measures how much electric charge a capacitor can store for a given voltage. The basic unit is the farad, defined as one coulomb of charge per one volt (C/V). So a capacitor with a capacitance of one farad would store one coulomb for every volt across its plates. In practice, you’ll see smaller units like microfarads, nanofarads, and picofarads, since a farad is quite large for common circuits. The other options aren’t units of capacitance: Henry is the unit of inductance, Ohm is the unit of resistance, and insulator is a non-conductive material, not a unit.
