Excerpt from Report to the International Committee on Electrical Units Standards of a Special Technical Committee Appointed to Investigate and Report on the Concrete Standards of the International Electrical Units and to Recommend a Value for the Weston Normal Cell: January 1, 1912 An extended investigation at the National Physical Labora tory had been carried out in 1906 - 7, in which the silver volta meter had been studied, and the electrochemical equivalent of silver determined to be mg per coulomb in terms of the absolute ampere, as measured by the current balance of that institution. The electromotive force of the Weston Normal Cell was given as at using the international Ohm as given by their own mercury units. The Rayleigh form of voltameter was most used in these experiments, but the Richards form with porous cups was also used, as well as the Siphon and other forms. All forms were found to give substantially the same results. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
