Book excerpt: Excerpt from Formulae and Tables, for the Calculation of Alternating Current Problems The importance of mathematics in the study of engineering problems is being generally recognized now and fully appreciated by engineers. The rapid development in alternating current engineering is largely due to the skillful utilization of mathematics in the study of the many complex phenomena which arise in connection with this subject. As a consequence the literature on alternating currents is distinctly mathematical. To be able to utilize fully all the acquired knowledge on this subject, one must have a sufficient mathematical training to enable him to follow the derivations of the many formulae, and be able to interpret them correctly. But even the engineer who has the mathematical equipment for this work is often obliged to consult a good many books and journals before he finds all of the formulae needed for his particular problem. An attempt has been made here to bring together in a small volume all the important formulae which are necessary and helpful in the solution of alternating current problems. The aim has been throughout to put the formulae in such form that they can be immediately applied for numerical calculations; and in those cases where it seemed desirable, the formulae are illustrated by numerical examples. In a work of this kind, which is in the nature of a compilation, the author has necessarily drawn freely from all sources of information, but in most cases the formulae were gone over carefully so as to make certain that they are free from errors. Frequently the formulae were derived independently, and in all cases an effort was made to put them in the simplest possible form. A few of the formulae appear here for the first time. The author is fully aware that accuracy and completeness are of first importance in a book of this character. To this end not only were formulae checked with care, but references to original authorities are generally given.
