Direct and Alternating Currents: Theory and Machinery

IN this volume the author reviews the theory of the electric circuit and the operating principles of electric machinery. The applications of electricity are now so numerous that it is very difficult to decide what to describe and what to omit. That everything has to be included in one volume makes it necessary to pass lightly over much theory, and since the student will in his future practice come across many types of equipment some of which it is necessary to describe, there is practically no space for modern theory. Luckily the laws and principles necessary to understand the performance of everyday electrical machines are few in number. The author has made a happy selection and the book will be useful to the technical student.Direct and Alternating Currents: Theory and Machinery.Prof.E. A.LoewBy. Pp. xiii + 656.
