The library is indebted to Mr.. Leon
White for the clear and comprehensive
review which follows:
For those desiring to acquire a
working knowledge of electricity and
its applications, a careful study of this
most practical library is bound to be
great aid.
There are eight guides, each covering
in detail certain phase of the broad
subject of electricity and leading the
reader progressively, and in such way,
that he easily grasps, not only the sim
pie fundamental facts, but the more |
complex problems encountered in the
study of electricity. This is accom-
plished by the aid of a very large mum
Der Of illustrations, together with spe
cific explanations, worded in a concise
and simple language.
Where it has been necessary to illus
trate and explain the various species
of commercial apparatus met with in
practice, it has been done in such a
manner as not to detract from the main
text. These descriptions have been
placed in small type directly under the
] illustrations, leaving space for an ade-
quate presentation of the underlying
| principles and theories, and for the
large amount of practical information
that is essential to obtain a general
knowledge of electricity and its numer-
GUS applications.
The main text has been written i'll
the question and answer form, as this
style of presentation has met with
hearty approval, not only from those
of limited education, but also from the
better informed.
Volume l takes up the nature, source
and kinds of electricity, primary CELLS,
conductors and insulators, magnetism
induction coils, dynamos and field mag
nets.
Volume takes up armatures and
armature windings, communication and
the commutator, brushes and brush
holders, armature construction, and Sc
ries, shunt and compound wound
motors.
Volume 3. GaVanometers, their con-
struction and application, are described
in this number in way which is sure
to be of interest to the student. The
chapters on testing and testing appara-
tus are especially good, as are the chap
, tiers on ammeters, volunteers and watt
meters. The operation and care of
dynamos and motors is taken up in the
remainder of this volume.
} Volume 4 is devoted to distribution
systems, wires and wire calculations, in.
, side and outside wiring, sign flashers and
? storage batteries. y lot of new material
r has been incorporated in the chapter
on storage batteries and should prove
of great benefit to all who own or have
the care of storage batteries.
Volume takes up the principles OF
, alternating current, its advantages an,
\ disadvantages, single phase, two phase
and three phase currents. The hydraul
c ic analogies of alternating currents u.
j treated in this volume are sure t
= bring to the student a clearer under
! standing of this subject. Alternatin.
/. current generators and their construc
ton is taken up in the remainder O
the volume
Volume 6 describes the various kinds
of alternating current motors and TIN,
principles underlying their operation
y | Descriptions and illustrations of modern
- types of motors and details of thei
! construction form an interesting par
l. of this chapter. The use of trans
: formers is taken up at length. Rotar,
- converters, motor generators, frequenc,
: changers and rectifiers form the sub
: jects of the remainder of the volume
G Volume covers alternating curren
|; systems, switching and regulating de
- vices, fuses, current limiting induct
/ ances, relays, air gap and electrolyti
lighting arresters, regulating devices
synchronous condcnsers and indication
devices, embodying the different kind
of instruments, watthour meters, FIRE
= quency meters, power factor Indicator,
n etc.
Volume s includes chapter on way
