Capacitance (noun)

1. A measure of the ability of a system, such as a capacitor, to store an electric charge.
2. The property of a circuit or device that determines the amount of electrical charge it can store per unit of voltage.

Origin:

Early 20th century, from the word 'capacity' meaning the ability to store an electric charge.

Examples:

1. The capacitance of the capacitor was measured using a specialized meter.
2. The capacitance of the system was critical in determining its performance and efficiency.
3. The capacitance was increased by adding more layers of insulating material between the plates.
4. The capacitance of the circuit was used to control the frequency of oscillation.
5. The capacitance played a key role in the design and operation of electrical and electronic systems.
