II has been estimated that the time

feature of the task is that after all this
effort the customer stiil remains igno-

the meihod OF electric measurement Is
devious device for concpaling nefn1
GUS practices by the electric light culu-
panies.
The average American Is perfectly
satisfied 10 buy gas by the foot trans

ana kiluwatts totally depraved This
difficulty might have been avoided II
the eminent scientists who trst adopt,
ed these accurate and 10 them conveu,
lent terms had been willing to show
the rest OF the world how to compute
electric quantity in feet and inches Or

The kilo Is an old friend Tor ancient

This leads to the definition OF watt
But In order to know watts one must
first learn about the two other mem
berS OF the family, amperes and volts.
Broadly speaking. nmperes measure
volume volts pressure and watts the
resulting quantity.
In order to get a tangible idea OF
the ampere. electricity may he com,
pared with water flowing through u
pipe. In this illustration the ampere
Will represent the volume OF water.
which is determined by the size Of the
pipe, but this should not he confused
with the size of The electric wire,
which has nothing 10 do with the pres.
ent problem. The nmpere then meas'
ures the volume OF current lowing In
the wire at given time. The quaint
ty OF energy flowing will depend upon
the other factor, which Is expressed
In volts.
The volt may be considered the meas
ure OF pressure or Intensity In the
Illustration or water lowing through u
pipe the pressure Is commonly express
ell In pounds to the square inch, witt
electric energy the same Idea Is ex
pressed In volts, II Is evident that the
quantity of water flowing IN pipe OF
a given size Will Increase MS the pres
sure increases, In II similar way The
quantity of electricity increases In ex.
act proportion to The electric pressure
OF voltage, and this quantity IL meas.
ured by watts
The quantity watts, of electricity
delivered over single circuit is the
direct product of the volume tumperes,
multiplied by the pressure volts, In
other words. umperes multiplied by
volts euuais waits.
