than electricity. What we see and
miscall steam Is merely water vnpor
when the steam h. condensing hack
into water. Steam itself Is quite in
visible.
Because electricity Ia Invisible Is no
reason why we should believe IL be-
longs 60 the mysterious. We really
know a great deal about g. We can
measure Il with the greatest accur-
acy and tell just how much work "a
given amount OF this energy will do.
We can easily figure out how much
light IL viii give. how much heat VI
viii produce. or how many horse
power OF work IL WI accomplish in
a given time.
There are three ways Of producing
electricity in quantities. Electricity
can be produced by friction, called
static electricity. but IN this form %
Is of no use commercially. except foi
experimental purposes.
Electricity can be- produced by the
action OF chemicals. The electric
battery is too well known 20 need any
description. The action of the chem
icals In breaking up ana tearing apart
the different chemical contents of the
battery requires considerable force
or energy. Energy cannot be lost but
II can he changed into other forms.
This chemical energy is changed into
heat energy and into electrical en-
ergy. The electricity produced la
this way can be used for various pur
poses.
Electricity such as We use for
light, heat and power vs. secured from
large magnets. The electric dynamo,
or generator. IN the power house is
really q series of powerful electro
magnets between the poles Of which

energy Is merely changed into cleo

dynamo, or generator, Is whirled hy

makes no difference what form ~

IL tho same. This mechanical energy
Is changed into electrical energy
This. In turn, can be changed into
light energy, into heat energy or
hack into mechanical energy through

Electricity IN easily measured We
know how fast Il travels over wire.
