Abstract
THIS book is intended to be a help to the teacher of physics, and consists of a collection of problems of vary ing difficulty in almost all the branches of electrical work. The third edition differs chiefly from the previous ones in the inclusion of some fresh problems and in the careful revision and correction of errors which has been made. The author has adopted the plan of giving the solution immediately after each problem, and, though objections may be urged against this method, we think on the whole it is the most satisfactory for a book of this kind. Those interested in electricity from its practical side will regret that most of the problems are of an academic character. Thus, to quote one example, the section on glow lamps gives the impression that lamps are usually made for 40 or 50 volts and that lighting is carried out by means of primary batteries. Occasionally one comes across a problem in which the data are not sufficient in reality. Apart from a few minor defects of this sort, the book is a very useful one, as the questions are well calculated to show whether or not the student has really grasped the meaning of the work he is doing, which should be the principal aim of a teacher. The addition of a short section on units and a number of tables enhances the value of the work.
