Second. The unit of current shall be what is known as the interna- ""P°"‘ tional ampere, which is one-tenth of the unit of current of the centimetergram-second system of electro-magnetic units, and is the practical equivalent of the unvarying current, which, when passed through a solution of nitrate of silver in water in accordance with standard specifications, deposits silver at the rate of one thousand one hundred and eighteen millionths of a gram per second. 1,,,,.,;,,,,,, Third. The unit of electro-motive force shall be what is known as the Wit- international volt, which is the electro·motive force that, steadily applied to a conductor whose resistance is one international ohm, will produce a current of an international ampere, and is practically equivalent to one thousand fourteen hundred and thirty-fourths of the electromotive force between the poles or electrodes of the voltaic cell known as Clark’s cell, at a temperature of tiiteen degrees centigrade, and prepared in the manner described in the standard specifications. quam;. Fourth. The unit of quantity shall be what is known as the interna- °“'""‘ · tional coulomb, which is the quantity of electricity transferred by a current of one international ampere in one second. capaany. Fifth. The unit of capacity shall be what is known as the interna- ’·"“'“‘· tional farad, which is the capacity of a condenser charged to a potential of one international volt by one international coulomb of electricity. Egylg- Sixth. The unit of work shall be the Joule, which is equal to ten ‘ million units of work in the centimetergram-second system, and which is practically equivalent to the energy expended in one second by an international ampere in an international ohm. , §`;;"j*· Seventh. The unit of power shall be the Watt, which is equal to ten ' million units of power in the centimeter-gram-second system, and which is practically equivalent to the work done at the rate of one J oule per second. g=•i¤<=¢i<>¤- Eighth. The unit of induction shall be the Henry, which is the °"”‘ induction in a circuit when the electro-motive force induced in this circuit is one international volt while the inducing current varies at the rate of one Ampere per second. h£:gji¤· *·· M v·¤‘·· Sec. 2. That it shall be the duty of the ational Academy of Sciences to prescribe and publish, as soon as possible after the passage of this Act, such specifications of details as shall be necessary for the practical application of the definitions of the ampere and volt hereinbefore given, and such specifications shall be the standard specifications herein mentioned.
