First published in 1916, as the second edition of a 1906 original, this book forms the second part of a two-volume series written to provide a guide to the more general mathematical theorems used by electricians in their everyday work. Illustrative figures are incorporated throughout the text. This book will be of value to anyone with an interest in electricity, physics and the history of science.
