Excerpt from Principles of Alternating Currents
This book has been developed from notes on Alternating Currents used for several years at the Massachusetts Institute of Technology with the junior students in Electrical Engineering. The portions of the notes dealing with single-phase currents were originally written by Professor H. E. Clifford, Gordon McKay Professor of Electrical Engineering at Harvard University, who was formerly Professor of Electrical Engineering at the Massachusetts Institute of Technology. The general arrangement and much of the material of these portions of the book arc substantially in the same form as originally written.
No attempt has been made to include problems other than those used to illustrate the principles discussed, as two sets of problems on alternating currents, much more comprehensive than could have been incorporated in the book, were already published by Professor W. V. Lyon under the titles "Problems in Electrical Engineering" and "Problems in Alternating Current Machinery."
The author wishes to express his indebtedness to Professor H. E. Clifford for the care with which he edited the manuscript and read the proof. The author also wishes to thank Professor W. V. Lyon for his many suggestions.
