Excerpt from Electricity and Magnetism for Engineers, Vol. 1: Electric and Magnetic Circuits In the following pages is given, from an engineering point of view, (1) a description of the more important effects commonly described as electric and magnetic phenomena, (2) a statement of the fundamental laws in accord with which these phenomena have been found to occur, and (3) the application of these laws to some of the simpler problems which arise in connection with the generation, transmission and utilization of electric energy. Particular emphasis is laid upon exact quantitative statements Of the fundamental laws or principles. Both safety and economy demand that the engineer be able to answer not only how, but also how much. To this end, the student of engineering should be taught to analyze, not only qualitatively, but also quantitatively, each problem which may be presented to him. Most of the simpler formulas used by scientists and engineers are special cases of certain general relations, and these special formulas are applicable only under certain specific conditions. One of the most common causes of confusion on the part of the beginner arises from his attempt to apply such special formulas to cases to which they are not applicable. This is due in part to the failure in many text-books to state the limitations of such formulas. Particular care is therefore taken in these pages to state specifically the exact conditions under which each formula is applicable. The procedure adopted throughout the book is to pass from simple phenomena, known to practically every school-boy, to the more complex phenomena and principles with which the engineer has to deal.

Particular emphasis is laid upon exact quantitative statements of the fundamental laws or principles. Both safety and economy demand that the engineer be able to answer not only "how," but also "how much." To this end, the student of engineering should be taught to analyze, not only qualitatively, but also quantitatively, each problem which may be presented to him.

The procedure adopted throughout the book is to pass from simple phenomena, known to practically every school-boy, to the more complex phenomena and principles with which the engineer has to deal. For convenience the book has been divided into two parts. Part I deals with the electric and the magnetic circuits, and Part II with electrostatics and alternating currents. Each part of the book can readily be covered in four hours of classroom work per week for a term. Part I may be looked upon as an introduction to the study of direct-current machinery, and Part II as an introduction to the study of alternating-current machinery.

Excerpt from Electric and Magnetic Circuits Electrical Engineering, deals with the fundamental principles of Electricity and Magnetism, and explains fully all the essential relationships of Electric and Magnetic Circuits met with in continuous current working, and it is hoped that the subjects of generation, transmission, distribution and application of electrical energy may receive full and adequate treatment in the succeeding volumes without requiring so much introductory matter, devoted to Electrical Engineering principles, terms and definitions, as is customary in many of the standard technical treatises. Furthermore, the experience of the author leads him to the conclusion that but few engineers are able to take full advantage of the classical works with which electrical literature abounds, simply and solely because they have not mastered thoroughly the elements of the Arithmetic of Electrical Engineering. The cultivation of the power and ability to calculate readily and accurately is just as important as the cultivation of the ability to do practical work; and to emphasize this fact the opinions of two eminent electrical engineers and educational authorities may be quoted. Twenty years ago Lord Kelvin made the following statement at a meeting of the Institution of Civil Engineers: In physical science a first essential step in the direction of learning any subject is to find principles of numerical reckoning, and methods for practically measuring some quality connected with it. I often say that when you can measure what you are speaking about, and explain it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind More recently, Professor Ayrton, F.E.S.
