What unit is used for capacitance?

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

Answer: (A)

Capacitance describes how much charge a capacitor can hold for a given voltage. The unit is the farad, defined as one coulomb per volt. So a 1 farad capacitor stores 1 coulomb of charge when the voltage across it is 1 volt. In practice, capacitors are smaller, so we use microfarads, nanofarads, or picofarads. A volt is a unit of electric potential difference, a coulomb is a unit of electric charge, and an ohm is a unit of electrical resistance—these describe other electrical quantities, not capacitance.
