Page 151 - Ampere, which is one-tenth of the unit of current of the CGS system of electromagnetic units and which is represented sufficiently well for practical use by the unvarying current which, when passed through a solution of nitrate of silver in water, in accordance with a certain specification, deposits silver at the rate of 0.001118 of a gramme per second.
Page 151 - As a Unit of Resistance, the International Ohm, which is based upon the ohm equal to io9 units of resistance of the CGS system of electromagnetic units, and is represented by the resistance offered to an unvarying electric current by a column of mercury at the temperature of melting ice, 14.4521 grammes in mass of a constant cross-sectional area, and of the length of 106.3 centimetres.
Page 113 - Great part of the information obtained in War is contradictory, a still greater part is false, and by far the greatest part is of a doubtful character.
Page 151 - As a unit of work, the joule, which is equal to 107 units of work in the CGS system, and which is represented sufficiently well for practical use by the energy expended in one second by an international ampere in an international ohm.
Page 151 - The unit of current shall be what is known as the international ampere, which is onetenth of the unit of current of the centimeter-gramsecond 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...
Page 151 - Henry, which is the induction in a circuit when the electromotive force induced in this circuit is one international volt while the inducing current varies at the rate of one Ampere per second.
Page 151 - As a unit of quantity, the international coulomb, which is the quantity of electricity transferred by a current of one international ampere in one second. As a unit of capacity, the international farad, which is the capacity of a condenser charged to a potential of one international volt by one international coulomb of electricity.
Page 151 - As a unit of electromotive force, the international volt, which is the electromotive force that, steadily applied to a conductor whose resistance is one international ohm, will produce a current of one international ampere, and which is represented sufficiently well for practical use by ^2.
Page 371 - All firing against earthworks when the shell bursts in the air is thrown away. The object is to lodge the shell in the parapets, and tear away the traverses under which the bomb-proofs are located. A shell now and then exploding over a gun en barbette may have good effect, but there is nothing like lodging the shell before it explodes.
Page 151 - Resolved, That the several governments represented by the delegates of this International Congress of Electricians be, and they are hereby, recommended to formally adopt as legal units of electrical measure the following : As a unit of resistance, the international ohm, which is based upon the ohm equal to 10°...
