Abstract
THE title of this book will doubtless lead those to whom “ohms,” “amperes,” “farads,” &c., seem so mysterious to hope that all difficulty in understanding what they are and whence they come will be removed. They will find, however, that though the relations between the practical units are given very clearly, and are illustrated by many numerical examples, yet the definitions are “definitions in a circle.” Mr. Swinburne has neither shown how the C.G.S. units are derived, nor has he even given the relations of the practical to the C.G.S. units.
Practical Electrical Units Popularly Explained.
By James Swinburne (late of J. W. Swan and Co., Paris; late of Brush Swan Electric Light Company, U.S.A.). (London and New York: E. and F. N. Spon, 1883.)
