Definition of capacitance

1a : the property of an electric nonconductor that permits the storage of energy as a result of the separation of charge that occurs when opposite surfaces of the nonconductor are maintained at a difference of potential
b : the measure of this property that is equal to the ratio of the charge on either surface to the potential difference between the surfaces
2 : a part of a circuit or network that possesses capacitance

Examples of capacitance in a Sentence

Recent Examples on the Web In traditional floating gates, insulators separate individual cells, which results in undesired capacitance between cells. Jim Salter, Ars Technica, 11 Nov. 2020 Micron's replacement-gate architecture instead builds multiple cells into a single insulating structure, virtually eliminating cell-to-cell capacitance, and (according to Micron) increasing write endurance, power efficiency, and performance. Jim Salter, Ars Technica, 11 Nov. 2020 Neurons firing action potentials that affect the downstream cells they are wired to (via synapses) are one type of mechanism, as are electronic circuits, made of transistors, capacitances, resistances and wires. Christof Koch, Scientific American, 1 Dec. 2019 Fingerprint scanners work on this same principle, just at a level small enough to measure the ridges and valleys of your fingerprint—a ridge will affect capacitance more than a valley, and thus an electrical fingerprint is measured. Ron Amadeo, Ars Technica, 29 Oct. 2018 Meanwhile, a capacitance sensor measures the electrical charge in the leaf. Nathan Hurst, Smithsonian, 27 Sep. 2017
