Which unit is used to measure capacitance?

• A. Watt
• B. Volt
• C. Farad
• D. Hertz

Answer: (C)

Capacitance is measured in farads, which is the correct unit for this electrical property. A farad defines the capacity of a capacitor to store an electric charge per unit of voltage applied. Specifically, one farad is the amount of capacitance that permits one volt of electric potential to charge a capacitor with one coulomb of electric charge. This relationship indicates that any device or component identified as a capacitor will utilize farads as its measure of capacitance, facilitating the design and analysis of circuits that require energy storage. In contrast, watts measure electrical power, volts measure electrical potential or voltage, and hertz measure frequency. Each of these other units is related to different aspects of electrical systems but does not quantify capacitance itself. Thus, farad is the only unit among the choices provided that specifically corresponds to capacitance, making it the appropriate answer.
