What is the unit of capacitance?

The unit of capacitance is the Farad. Capacitance is defined as the ability of a component or circuit to store electrical energy in the form of an electrical charge. One Farad is defined as the capacitance of a capacitor when one coulomb of charge stores one volt of electrical potential. This relationship highlights how capacitance, voltage, and charge are interrelated in electrical systems.

Capacitors, which store electrical energy, are characterized by their capacitance value measured in Farads. When working with circuits, understanding the role of the Farad helps technicians design and troubleshoot systems that utilize capacitors effectively.

In contrast, Ohm is the unit of resistance, Volt is the unit of electrical potential, and Watt is the unit of power. Each of these has a specific role in electrical engineering but does not represent capacitance. Thus, identifying Farad as the correct unit emphasizes the importance of capacitors in circuit behavior and energy management.
