This work is intended to form a systematic course of instruction in "Electrical Testing" connected with Physics and Electrical Engineering. It is difficult, if not well-nigh impossible, to draw any distinctive line between a vast number of experimental investigations in that branch of Physics termed “ Electricity and Magnetism” and the more elementary portions of Electrical Engineering. In fact, the latter may be regarded as the development of the former and almost entirely dependent on it. Thus the author has little hesitation in recommending the following course of experimental work as eminently suitable for constituting the electrical laboratory practice in the first and second years of a complete course in Electrical Engineering as well as in Physics.
The author includes in a separate work a large variety of tests in advanced electrical engineering work, such as might well constitute the latter part of a complete course of instruction in this branch of industry. As far as has been practicable, the experimental investigations have been arranged in the order in which they may be worked, but exceptions have arisen owing to the advisability of keeping certain tests of a similar nature together. The arrangement adopted is in a measure similar to that which has been in use for some years past at the Central Technical College of the City and Guilds of London, but is a considerable extension of that arrangement. The author has endeavoured to make the several tests as complete and descriptive as possible, and in addition to the “ Introduction ” of each, which contains the principal theoretical considerations pertaining to the test, condensed as much as possible, a complete digest of the method of performing the experiment with a diagram of apparatus and connections, represented symbolically, and the most convenient and suitable
