The field of electrical measurement continues to grow, with new techniques developed each year. From the basic thermocouple to cutting-edge virtual instrumentation, it is also becoming an increasingly "digital" endeavor. Books that attempt to capture the state-of-the-art in electrical measurement are quickly outdated. Recognizing the need for a tex

Excerpt from Magnetism and Electricity: And the Principles of Electrical Measurement The object of this book is to provide a sound and systematic course of study in the main principles of Electricity and Electrical Measurement. It is written to meet the requirements of students who have already, in a first year's course, made some acquaintance with the elementary descriptive parts of the subject, and are commencing the study of Electricity in its more quantitative aspects, either as a branch of pure Physics or as a preparation for a course of Applied Electricity. In the choice of subject-matter regard has been paid to the demand made on the student's knowledge of auxiliary and correlative subjects. Most students obtain, in conjunction with their first year's course, a knowledge of the elements of Algebra, Mechanics, and Heat; such preparation has therefore been assumed. On the other hand, the student cannot at this stage be expected to have acquired familiarity with the principles of Thermodynamics, the Theory of Wave Propagation, or the Kinetic Theory of Gases. Portions of the subject requiring a knowledge of these or similar branches of higher Physics have therefore been strictly excluded. By this means, also, a more satisfactory treatment of the main principles, and a more adequate explanation of points of special difficulty, have been made possible. For convenience of reference a brief résumé of the fundamental properties of magnets, electric charges, and currents is given in Chapters I, VIII, and XVIII.
