An Elementary Treatise On Alternating Currents PDF Download

Excerpt from An Elementary Treatise on Alternating Currents Having been for some years engaged in lecturing to advanced students on the subject of alternating currents the author has endeavoured to present, in as simple a manner as possible, a subject which, though intensely interesting in its purely physical aspect, is often expounded by mathematicians who, while revelling in the mathematical gymnastics afforded by its problems, so bewilder their less mathematical readers by the adoption of unnecessarily ponderous methods that the majority give up in disgust a subject which would otherwise exercise great fascination for them. That such should ever happen is lamentable in the extreme, since it retards the progress of the practical application of alternating currents. The author has employed the method of vector algebra wherever possible to solve the various problems, as he has found that it is quite easy for a student knowing only the elements of algebra and trigonometry to obtain a good working knowledge of the method in a very short time, and become enabled to attack problems which are otherwise beyond his comprehension. The application of vector algebra to alternating-current problems should appeal to everybody. It is a tool peculiarly adapted to the subject, and combines simplicity with all the advantages of a powerful method. No one will dispute the use of a treatise on the subject in which the chief aim of the writer is to eliminate mathematical difficulties and give prominence to the physics of the subject. Since the author has engaged in practice as a consulting engineer he has found that the want of a simple though comprehensive treatise is often a deterrent to practical engineers acquiring a requisite knowledge of the subject.
