Page 634 - As a unit of resistance, the international ohm, which is based upon the ohm equal to 10° units of resistance of the CGS system of electro-magnetic 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 centimeters.
Page 816 - As a unit of electro-motive force, the 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 one international ampere...
Page 567 - As a unit of current, the international ampere., which is one-tenth of the unit of current of the CGS system of electro-magnetic units, and »hich is represented sufficiently well for practical use by the unvarying current which, when passed through a solution of nitrate of silver in water, and, in accordance with accompanying specifications,1 deposits silver at the rate of 0-001118 of a gramme per second.
