Publisher's Synopsis
Excerpt from The How and Why of Electricity: A Book of Information for Non-Technical Readers
Silver is the best conductor, copper being very nearly as good. The latter metal is used in enormous quanti ties for conducting wires and cables. All the metals and their alloys are conductors. Iron and steel conduct fairly well, but only about one-seventh as well as copper. Carbon, such as graphite and pure charcoal, is a very poor conductor, although in some special forms it is made use of as a conductor, as in electric batteries, in telephone protective devices, and in many processes of electrolytic decomposition. Solutions of metallic salts are intermediate conductors. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
