ca·pac·i·tance \kəˈpasətən(t)s, -əd.ən-\ noun (-s) Etymology: capacity (I) + -ance 1. : the property of an electric nonconductor that permits the storage of energy as a result of electric displacement when opposite surfaces of the nonconductor are maintained at a difference of potential (as in a capacitor), its measure being the ratio of the charge on either surface to the potential difference between the surfaces and its value for a capacitor being the sum of the combined values of its several dielectric plates — called also capacity 2. : a part of a circuit or network that possesses capacitance |
