What is the unit for measuring capacitance?

Capacitance is quantitatively defined as the ability of a component or circuit to store electrical energy in an electric field. The international unit of capacitance is the farad, which is a derived unit in the International System of Units (SI). One farad is defined as the capacitance of a capacitor that charges to one coulomb of electrical charge when a potential difference of one volt is applied across it. This relationship highlights how capacitance is fundamentally linked to both charge and voltage, making the farad the standard unit for measuring this property.

In contrast, the henry is the unit of inductance, the ohm is the unit of resistance, and the watt is the unit of power. Each of these units corresponds to different electrical properties, making farad the only relevant choice for measuring capacitance. Understanding these fundamental units is crucial for analyzing and working with electrical circuits and components.
