Excerpt from Practical Electricity, Vol. 1: Laboratory and Lecture Course, for First Year Students of Electrical Engineering, Based on the International Definitions of the Electrical Units, Current, Pressure, Resistance, Energy, Power and CellsExactly ten years have elapsed since the preface to the first edition of this book was written - a decade which has seen a'vast development in the applications of elec tricity to industrial purposes, and the springing up in all parts of the kingdom of Technical Schools and Colleges where much attention is devoted to the study of electro technics. Hence, to day it IS far more easy for a student to connect his experimental apparatus with the electric light mains and use a comparatively large current at a pressure of 100 volts, than it was in 1886 to obtain a small current at a much lower pressure from the battery which he had to set up for the purpose. This possibility of carrying out the experiments on a larger scale has led to considerable simplification in certain cases, for ex ample, ih experimentally determining the heat equivalent of electric energy, it 'is no longer necessary to distract the beginner's attention with a variety of corrections for the loss of heat, &c., About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
