Which unit is used to measure capacitance?

Capacitance is measured in Farads, which is the standard unit of capacitance in the International System of Units (SI). A Farad is defined as the amount of capacitance that allows one coulomb of electric charge to change the potential difference by one volt. In practical terms, it indicates how much electrical energy a capacitor can hold per volt of electric potential.

When discussing capacitors, it's important to understand that they store energy in an electric field when a voltage is applied across their terminals. The ability of a capacitor to store charge is directly related to its capacitance, making the Farad the most appropriate unit for quantifying this property.

Other options represent different electrical concepts: Henries measure inductance, Amperes measure current, and Volts measure electric potential. Each serves a distinct purpose in electronics, but only the Farad pertains specifically to capacitance.
