Print on Demand. This book is a study of the development of the concept of the absolute ampere, which is a unit of electrical current defined in terms of the fundamental units of mass, length, and time. The author traces the history of the ampere from its origins in the work of Gauss and Weber in the 1830s to its refinement by scientists in the early 20th century. The book discusses the importance of the absolute ampere in the development of electrical science and its role in the standardization of electrical measurements. It also examines the challenges and controversies that have surrounded the definition of the ampere, and the impact of these controversies on the development of electrical engineering. The book provides a detailed and comprehensive account of the development of the absolute ampere, and it is an essential resource for anyone interested in the history of electrical science. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.…

Inasmuch as precise electrical measurements are usually made in terms Of standard resistances and standard cells, it would simplify the problem if a voltage instead Of a current were directly determined in absolute measure. The direct determination Of the volt with precision in absolute measure, however, presents very formidable difficulties and has never been made. It was largely for this reason that the ampere was chosen as the second independent unit instead Of the volt. Many absolute measure ments Of the ampere and Of the Ohm have, however, been made since Gauss and Weber first showed in 18 32 that a system Of absolute units is possible. These determinations, having been made at different times and at different places, can be com pared only by comparing the various concrete standards adopted at the different times. As there can be no concrete standard ampere, two expedients have been adopted for preserving the results Of the absolute measurement Of current. That most favored in the past is to determine the mass Of silver deposited per second in a silver voltameter by a current Of one ampere; the other, which in many cases in the past served as intermediary between the absolute determination and the silver voltameter measurement, is to determine the electromotive force of a certain standard cell in terms of a standard of resistance and the absolute ampere determined by the balance.
