Electric Illumination, Bind 1James Dredge Cambridge University Press, 18. dec. 2014 - 904 sider Two years after Thomas Edison patented his electric light bulb, the 1881 International Exposition of Electricity in Paris, featuring many spectacular lighting displays, showcased the potential of this technology for commercial and domestic use. The accompanying International Congress of Electricians also agreed on international standards for units of electrical resistance, potential and current. In its wake, James Dredge (1840-1906), editor of the British periodical Engineering, compiled this illustrated overview of electrical technology and its application to lighting. First published in two volumes between 1882 and 1885, and using material that had previously appeared in Engineering, as well as new articles by various contributors, this substantial work reflects the complexities and possibilities of a propitious technological development. Among other topics, Volume 1 covers electrical units, methods of generation, conductors, and various kinds of lamp. The appendices give abstracts of British electrical patents from 1837 to 1872. |
