Modern Electrical Theory e-bog

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The scope and intention of this volume need some explanation. It was begun with the idea of providing a text-book from which students, well grounded in the elementary branches of physics, might obtain some knowledge of the later developments; there is 'no doubt that such a book is needed urgently. But, in the course of writing, departures from the original scheme have been made. There are lengthy descriptions of theories which may be assumed to be familiar to such students, and there are discussions of controversial questions which may be thought undesirable in the early stages of study: it is improbable that a reader, who could gain much new information from the first chapter, could gain much benefit from the last. On the other hand, the book does not aspire to the dignity of a treatise designed to bring the results of the latest original research to the notice of those who have made a special study of the newer branches of physics: there is little that is not well-known to all professed students of the subject.
