Page 71 - 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 72 - 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. As a unit of work, the joule, which is equal to 10...
Page 72 - 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. As a unit of power, the watt, which is equal to 10...
Page 71 - ... 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 \\\% of the electromotive force between the poles or electrodes of the voltaic cell known as Clark's cell, at a temperature of 15° C., and prepared in the manner described in the accompanying specification...
Page 71 - 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...
Page 71 - The unit of electromotive force shall be what is known as 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...
Page 71 - 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 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 grams in mass, of a constant cross-sectional area and of the length of 106.3 centimetres.
Page 822 - NOTICE. 1. The Institution's Library is open to members of all Scientific Bodies, and (on application to the Secretary) to the Public generally. 2. The Library is open (except from the 14th August to the 16th September) daily between the hours of...

Page 36 - Professor H. ROBINSON : I have much pleasure in seconding the resolution so well moved by General Webber, but I feel confident that it requires no words from me to commend it to the meeting. I know that all who have heard the President's Address will say that it is of deep interest, both to the older as well as to the younger members. The Address is stamped with a broad view of the requirements of the case, both with regard to the present and the future ; and whilst older members of the Institution...
