Abstract
THE second edition of this text-book is a creditable effort on the part of the author to cover, in a single volume of 730 pages, the extensive field embracing the theory and applications of direct and alternating current circuits, machinery and apparatus. Numerous examples are given to illustrate the principles of direct current and alternating current machinery and in addition there is a selection of problems, at the end of most chapters, which are suitable for tutorial classes. The treatment of the subject is of an introductory nature, but, although not sufficiently advanced to suit the requirements of a degree course syllabus in a British university, this book would assist students attending a course of lectures on a general survey of the subject of D.C. and A.C. machinery and apparatus. Throughout the book there is evidence of the restriction, imposed by lack of space, on the treatment of the problems involved and this offsets much of the gain in having the whole subject in a single volume.
