A Book of Practical Examples in Electricity

Nature volume 49, pages 145146 | Download Citation



THIS is, in the main, a book of fully worked-out exercises in electricity and magnetism, designed for the help of practical students. Its idea and arrangement are good, and the examples seem to have been chosen with much care, and, as far as possible, from actual cases which have occurred in laboratory and practical work. The aim of the author has not been to furnish a set of examples, like the collection of Walton, in theoretical mechanics, or that of Hall Turner, in heat and electricity. These works illustrate general mathematical theories by examples, the solutions of which are in many cases important or interesting particular theorems; but their interest is, to a great extent, mathematical. M. Witz has had in view the wants of students endeavouring to obtain a sound elementary knowledge of electricity, who are not afraid of a piece of calculation involving, when necessary, a little differentiation or integration, when it its proper place as the simplest and most direct means of attaining the required result.
