Présentation de l'éditeur
In most cases no argument is needed to convince the practical station man of the advantage of getting this working knowledge. But unfortunately there seems to be a general impression that no one who is not an expert mathematician or a college graduate can get much useful information out of a book on alternating currents. Knowing only the rudiments of algebra, geometry, and trigonometry, the beginner soon gets beyond his depth in a sea of advanced mathematics, becomes discouraged, and finally gives up in disgust. It is precisely for him that this book is written. It contains no mathematics beyond the simplest trigonometry; and great pains have been taken to make the descriptions, explanations, and proofs simple and clear. The reader is assumed to have some acquaintance with the elementary laws of electricity and magnetism. C| Graphical, or geometric, methods rather than analytical, or algebraic, methods have been adopted wherever possible, as will be seen in the repeated application of the clock diagram in determining the relations between electromotive forces and currents in the various types of apparatus discussed. Abstract and arbitrary statements have been reduced to a minimum; and on the other hand, a large variety of examples and numerical illustrations have been used throughout the text to reinforce the principles by concrete applications.
