Book Description

Excerpt from A Course in Electrical Engineering, Vol. 2: Alternating Currents This volume is intended for those who have such a knowledge of direct currents as is given by Volume I. It presupposes no knowledge of alternating currents. The first two chapters are devoted to the development of the fundamental laws of alternating currents and alternating-current circuits. Subsequent chapters consider the application of these fundamental laws to alternating-current measurements, to polyphase circuits, to alternating-current machinery, and to power transmission. A chapter on illumination and photometry has been included, as a brief discussion of the underlying principles of light and of light measurements is important in a general course in electrical engineering. The development of the various alternating-current formulas and of the operation of various types of machinery, transmission lines, etc., are based on the fundamental laws of electricity and magnetism as set forth in Volume I. Mathematical developments are occasionally introduced, as supplementary to the descriptive matter. As in Volume I, numerous illustrative problems and methods of making laboratory tests are given throughout the text. This volume is intended to be elementary in character and to act as a stepping stone to the more advanced texts of this series. In many cases rigorous and detailed analysis is not given, particularly in the chapter on alternating-current measurements and in the discussion of certain types of alternating-current apparatus. A thorough analysis of these subjects is found in "Electrical Measurements" by F. A. Laws, and "Principles of Alternating Current Machinery" by R. R. Lawrence, both of which volumes are included in this series of Electrical Engineering Texts. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
