The farad is the unit of which quantity?

The farad is the unit of which quantity?

• A. Inductance
• B. Capacitance
• C. Resistance
• D. Magnetism

Answer: (B)

Capacitance is the ability of a device to store electric charge per unit voltage. The farad is the unit for this quantity. By definition, C = Q/V, where Q is the charge in coulombs and V is the voltage in volts. So the unit of C is coulombs per volt, which is a farad. A practical note: one farad is a very large capacitance, so real components are often expressed in microfarads, nanofarads, or picofarads. The other options correspond to different quantities: inductance uses henries, resistance uses ohms, and magnetism is described by units like weber or tesla, not a farad.
