(1) A Treatise on the Elements of Electrical Engineering (2) Continuous-current Motors and Control Apparatus (3) Power Wiring Diagrams

Abstract

(1) TT is usual for writers of books on electrical J- engineering- to confine themselves to the theory either of direct-current or of alternating-current practice. In an elementary treatise, how ever, it is best to include both, and this the author has done. A most satisfactory feature is the intro duction of the concepts of the modern theory of electrons, and this greatly stimulates the interest of the reader in many of the phenomena and appa ratus described. Other excellent features are a free use of the calculus-we were impressed by the pains taken to make the mathematics simple-and the introduction of many easy problems.
