1777 T. Cavallo Compl. Treat. Electr. ii. i. 103 The celebrated Father Beccaria supposes that the action of rubbing increaseth the capacity of the Electric, i.e. renders that part of the electric, which is actually under the rubber capable of containing a greater quantity of electric fluid.

1903 Westm. Gaz. 25 Feb. 5/1 The oscillatory circuit consists of a light wire cage, or ‘capacity’.

1906 A. F. Collins Man. Wireless Telegr. 209 Capacity cage, a cylindrical cage made of wire and placed at the top of the aerial wire to give it additional capacity.

1923 Daily Mail 3 Mar. 5 If you are particularly bothered by the proximity of wires it is worth while to try the effect of substituting a ‘capacity earth’ for the ordinary earth connection. The capacity is a wire or wires stretched out below and parallel to the aerial above but insulated from the earth.

1932 C. J. Smith Intermediate Physics xxxix. 507 The capacity of a sphere expressed in E.S.U. is numerically equal to its radius in centimetres.

1948 C. A. Coulson Electr. 43 If the potential difference between the plates is V, we define the capacity C by the formula C = Q/V.

1959 Chambers's Encycl. III. 826/1 The capacity of the charged conductor is..increased, i.e. it can hold a bigger charge for a given potential.
