What does capacitance measure in an electrical system?

Capacitance measures the ability to store an electric charge in an electrical system. This property is a fundamental aspect of capacitors, which can accumulate and hold electric charge when a voltage is applied across their terminals. The amount of charge that a capacitor can store is directly proportional to the voltage across it and is defined by the capacitance value, measured in farads. This property is crucial in various applications, such as timing circuits, filtering signals, and stabilizing power supplies. Understanding capacitance is essential for designing and analyzing circuits that rely on the energy storage capabilities of capacitors.
