A complete musical sentence. The period, the present or current time, as distinguished from all other times.

The quality or state of being periodical, or regularly recurrent; as, the periodicity in the vital phenomena of plants. Henfrey.

ommutator and rotating brushes, in which the exciting field is induced by the alternating current in a short-circuited magnetic core instead of being produced by an external magnet.

A machine for converting an alternating current into an alternating current of a different number of phases and the same frequency.

A charge of phase whereby an alternating current attains its maximum later or earlier. An inductance would cause a lag, a capacity would cause an advance, in phase.

A device for measuring the difference in phase of two alternating currents of electromotive forces.

A device by which a single-phase current is split into two or more currents differing in phase. It is used in starting single-phase induction motors.

The dephasing of the two parts of a single alternating current in two dissimilar branches of a given circuit.

of two electrodes embedded in selenium) which by exposure to light generates an electric current.

mate, life, etc., and of the physical movements or changes on the earth's surface, as the currents of the atmosphere and ocean, the secular variations in heat, moisture, magnetism, etc.; physical geography.

d up with disks of cloth or paper moistened with acid water between them, for producing a current of electricity; -- commonly called Volta's pile, voltaic pile, or galvanic pile.

A small, unmanned balloon sent up to indicate the direction of air currents.

on a dynamo or battery circuit to show approximately by its brightness the voltage of the current.

A facing of stone laid upon a bank to prevent wear by tides or currents. Pitching piece (Carp.), the horizontal timber supporting the floor of a platform of a stairway, and against which the stringpieces of the sloping parts are supported.

end under water, and observing the height to which the fluid rises in the tube; a kind of current meter.

A small copper coin formerly current in Scotland, worth less than a cent. With not a plack in the pocket of the poet. Prof. Wilson.

lectrolytic cell, by the deposition upon them of the gases liberated by the action of the current. It is chiefly due to the hydrogen, and results in an increase of the resistance, and the setting up of an opposing electro-motive force, both of which tend materially to weaken the current of the battery, or that passing…

ucing two or more pressure waves of electro-motive force, differing in phase; a polyphase current.

In a popular manner; so as to be generally favored or accepted by the people; commonly; currently; as, the story was popularity reported. The victor knight, Bareheaded, popularly low had bowed. Dryden.
