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 embarassing. It is believed that some
success has been attained in overcoming or compromising
difficulties such as those suggested.
Enough tables have been introduced to fill the
limits of the subject as here treated.
The full development of electrical laws involves
the higher mathematics. One who would keep up
with the progress of the day in theory has a severe
course of study before him. In practical work it is
believed that snch a volume as the Arithmetic of
Electricity will always have a place. We hope that
it will be favorably received by our readers and that
their indulgence will give it a more extended field of
usefulness than it can pretend to deserve.
Can you see something in electricity that has been
overlooked for over a hundred years?
This could be the subject that could
change your life...
