Arithmetic of Electricity
A Practical Treatise on Electrical Calculations (Classic Reprint)

Excerpt from Arithmetic of Electricity: A Practical Treatise on Electrical Calculations

The solution of a problem by arithmetic, although in some cases more laborious than the algebraic method, gives the better comprehension of the subject. Arithmetic is analysis and bears the same relation to algebra that plane geometry does to analytical geometry. Its power is comparatively limited, but it is exceedingly instructive in its treatment of questions to which it applies.

In the following work the problems of electrical engineering and practical operations are investigated on an arithmetical basis. It is believed that such treatment gives the work actual value in the analytical sense, as it necessitates an explanation of each problem, while the adaptability of arithmetic to readers who do not care to use algebra will make this volume more widely available.

In electricity there is much debatable ground, which has been as far as possible avoided. Some points seem quite outside of the scope of this book, such as the introduction of the time-constant in battery calculations. Again the variation in constants as determined by different authorities made a selection embarrassing. It is believed that some success has been attained in overcoming or compromising difficulties such as those suggested.
