ELECTRICAL TERMS.

Eiectzode-A pole Of batAry.
Power-TheE ase1 doing work.
Pole-The tesnihabof = geoerator.
Candida unit of Illuminating power.
Anode-The positive pole Of . battery.
FsradEThe unit Of electrical capacity.
Arnature-The revolving arm of an cleo
tric generator.
Circui-The path along which an electric
current travels.
Cell-The vessel in which chemical action
produces electricity.
Electromotive Force-The power that con-
stltutes or moves electricity.
Positive-The point Of generator where
the positive current leaves it.
Rasistance-Fhe opposition that current
meets In travexzing q conductor.
Dynamo-Machine for converting mechaa-
ical power into electrical energy.
Coulomb-The unit Of dynamic quantity
represented by one ampere Of current
Watt-The units of electrical power repre-
sented by one volt multiplied by one ampere
Commutator-The collector of the cleo
taken by the brushes.
Condenser-An arrangement for collecting
large quantity of electricity on small sur
face.
Conductivity-The comparative ability Of
p substance to convey current of electricity.
Potential-Appliable e3ectro-motive force
corresponding to pressure or head in hydrau-
lies.
Conductor of the electric,cr-
rent, silver being the best, and copper next,
in conductivity.
Core-The iron that becomes magnetized in
an electro magnet. In helix, this iron is of
the softest kind
Voh-The unit of electro-motive force. One
volt win force one ampere Of current through
one ohm Of resistance.
Galvanometer-An instrument for meas
the presence of electricity.
Brush-The copper string which connects
with the commutator of a dynamo and gath
ers the electricity for the conductors.
Jule-The union Of heat and work which is
expended in forcing one coulomb through
one ohm. Itequals 1878 foot'pound.
Magnolia magnetized piece of iron or
steel, capable of attracting iron or steel bod
les, and of inducing electric currents.
Archie space between the points Of the
carbons in an electric light or lamp which is
bridged by the current represented by the
fame.
Ohm-The unit of resistance represented
by the resistance through which one ampers
of current will flow at a pressure of one volt
electro-motiye force.
Horse Power, Electrical-A unit of power
equaling TAG watts of electrical energy. A
current Of one ampere and TAG volts is an
electrical horse power.
Current-The flow Of electricity along a
conductor. Its strength in amperes is found
by dividing the electro-motive force in volts
by the resistance in ohmS
Polarity-A magnet suspended SO that its
unrestricted in any direction,
will turn one point to the north, the other to
the south. Hence the North and South poles
Of the magnet
Negative-The terminal of q generator,
where the positive current returns after
its circuit. Negative electricity is
an amount less than the substance would na-
turahy contain.
Carbons-Rods Of carbon are used in arc
lights for first establishing the current, and |
then, when Withdrawn, form the arc over
which the electric fame leaps. They are |
made of powdered cokeby a secret process.
Storage Of secondary bat
terry, in which electricity has been carried |
and has been converted into chemical energy, |
49,
the battery is put to use for the purpose of |
furnishing energy or light.
Electro Magnet-The soft iron. core around |
which insulated wire is wound 1t becomes
highly magnetized when the current is sent |
through the coil, and is much more powerful
than permanent magnet, but It's magnetism
is lost when the current is broken.
Ampere-The unit of the strength of the
per second 1t represents, perhaps,
the volume of electricity, and its vafne Is the
quantity Of the fluid which flows per second
through one ohm Of resistance when tmpea4ed
BY ono volt OF electCo-motive force.
Isulstors- possessing high re-
istauce, such as glass vulcantzed rubber,
paratine, etc. When covering a wire along
which an electric current is passing itpre-
vents loss of power by CONJUNCTION, and makes
the wires heavily charged safer for handing.
Induction-The property by which one
body having electrical, galvanic or magnetic
polarity causes it or induces it in another
body without having actual contact. In
,ther words, an impress Of molecular force
,rconditions from one body on another with
,ut direct contact. An electric current in
Hne.indnces currents in conductors parallel
