Excerpt from Electrical Engineering This book is intended to give a survey of the principles of electrical engineering which shall be as complete as is practicable in one volume of moderate size. Commencing with the foundation experiments the aim has been to give in logical sequence the steps by which the practical formulae and other results are reached. The science of electrical engineering is based on fundamental experimental facts, which may be summarised as follows: 1. Coulomb's inverse square laws for electric charges and for magnetic poles.2. Faraday's law of electromagnetic induction.3. Ohm's law of electric resistance.4. Faraday's laws of electrolysis.5. Ampere's laws of the equivalence of electric currents and magnetic shells.6. Joule's law of the heat energy of an electric current. The plan of this book is formed on the recognition of this foundation basis of the science, and special emphasis has been placed on the importance of these laws. In Section I. the principles of static electricity are dealt with in considerable detail. This subject usually has been treated in a rather cursory manner in electrical engineering books. In view of the increasing importance to engineers of a thorough study of this branch, especially in connection with more recent developments, such as high-tension long-distance transmission, graded cables, wireless telegraphy, etc., the amount of space devoted to it in the book is thought to be justified. Generally, electrical engineering students are expected to obtain detailed kwledge of static electricity from books on physics, and as the writers of such books do t usually write from the engineer's point of view, their methods are t always so convincing to him as they might be.
