Sign in to saveAlso known as electrostatic capacity, electric capacitance
Capacitance is the ability of an object to store electric charge. It is measured by the change in charge in response to a difference in electric potential, expressed as the ratio of those quantities. Commonly recognized are two closely related notions of capacitance: self capacitance and mutual capacitance. An object that can be electrically charged exhibits self capacitance, for which the electric potential is measured between the object and ground. Mutual capacitance is measured between two components, and is particularly important in the operation of the capacitor, an elementary linear elec
Capacitance is the ability of an object or pair of objects to store electric charge, measured by how much charge builds up when an electrical voltage is applied. It matters because it's a fundamental property that explains how capacitors—common components in electronics—work and how electrical systems store and manage energy.
