An allotropic form of oxygen. It possesses much more energetic chemical
properties than oxygen. It is supposed to contain three atoms of oxygen
in its molecule, represented thus:
O / \ O—O
It is produced by electric discharges and it is its peculiar odor which
is noticed about an electric machine, and sometimes in a thunderstorm
near the path of [...]

A dynamo or motor whose armature is placed above or in the upper part of
the field magnets, the yoke piece of the magnets being in or resting
upon the base of the machine.

In an electric motor a mechanical load put upon it so great as to
prevent economical working. One effect of such a load is to make the
armature run so slowly as to unduly reduce the counter-electro-motive
force and hence to permit so much current to pass through the coils as
to heat them, perhaps injuriously. In this case [...]

A proportioning of the series and shunt windings of a compound dynamo,
so that the voltage of the terminals rises with the load or output
enough to allow for the drop in mains, thus maintaining the potential
for full load at distant points in a district. It is carried out by an
increase of ampere-turns in the series winding.

As a unit of output of a dynamo Prof. Sylvanus P. Thompson has proposed
1,000 watts, or one kilowatt. This unit is now frequently used. To
completely define the dynamo, however, the amperage or the voltage must
also be given, as a 10 kilowatt–110 volt machine, or a 10 kilowatt–99
ampere machine.
[Transcriber's note: 10 kilowatt at 110 volts is [...]

The analogue in a magnetic circuit of the output of an electric circuit.
It is the product of the magnetizing force by the induced magnetism.

The rate of energy delivered or of work done by a machine. In the case
of a current generator it is the volt-coulombs per given second, or
better the volt-amperes delivered at its outer circuit terminals.

The part of an electrolier or electric light fixture out of which the
wires are led for attachment of an incandescent light socket.

Induction produced by sympathetic action of an oscillatory discharge or
by electric resonance. (See Oscillations, Electric–Resonance,
Electric–Resonator, Electric.)

Hypothetical displacement currents of rapidly alternating direction
produced in the oscillatory discharge of a Leyden jar or static
condenser.
