Présentation de l'éditeur
For some years the author has been engaged in lecturing on electrical matters to the students of Engineering at theE ngineering Laboratory, Cambridge, and he has experienced a difficulty in recommending to the men a suitable book on this subject. In the course of study for theM echanical Sciences Tripos the subject of Electrical Engineering is but one of several, and consequently a student has not the time to devote to a proper study of the larger books already available either in English orG erman, and the smaller books scarcely cover the ground with which the course deals. Hence it was felt that a compilation of the more important points was desirable. It was also hoped that such a compilation might possibly be of some use to teachers in general. In such a book as the present, dealing merely with the broad outlines of the subject, little that is not common knowledge can be embodied, and hence very few references are given. To the student such references are merely distracting, and to a more learned person (should such a one honour the author by reading the book) they are unnecessary. The treatment of the question is largely based on the use of vectors, supplemented by simple analytical methods when it is desired to obtain numerical results. The symbolic treatment has been found by the author to appeal to a very limited number of students, and hence has not been used. Throughout the expressions are worked out in general terms that is, no attempt is made to distinguish in the formulae whether absolute or practical units are employed.
