e tangent of the angle of deflection of the needle is proportional to the strength of the current. -- Tangent of an angle, the natural tangent of the arc subtending or measuring the angle. -- Tangent of an arc, a right line, as ta, touching the arc of a circle at one extremity a, and terminated by a line ct, passing…

d by the movements of the object to be measured, causes variations in the strength of the current, which variations are indicated by a sensitive galvanometer. It is also used for measuring minute changes of temperature. T. A. Edison.

ons of the pencil are communicated by levers to two rotary shafts, by which variations in current are produced in two separate circuits. In the receiver these variations are utilized by electromagnetic devices and levers to move a pen as the pencil moves. --Tel`au*tog"ra*phist (#), n.

producing music (Tel*har"mo*ny []), at a distant point or points by means of alternating currents of electricity controlled by an operator who plays on a keyboard. The music is produced by a receiving instrument similar or analogous to the telephone, but not held to the ear. The pitch corresponds with frequency of alt…

r road over which vehicles for carrying loads are moved by electric engines actuated by a current conveyed by the line.

An extensive current of wind, rushing with great velocity and violence, and commonly attended with rain, hail, or snow; a furious storm. [We] caught in a fiery tempest, shall be hurled, Each on his rock transfixed. Milton.

To comply with the time or occasion; to humor, or yield to, the current of opinion or circumstances; also, to trim, as between two parties. They might their grievance inwardly complain, But outwardly they needs must temporize. Daniel.

ectric motor, usually provided with binding screws for the attachment of wires by which a current may be conveyed into or from the machine; a pole.

A transformer without iron, for high frequency alternating or oscillating currents; an oscillation transformer.

Pertaining to thermoelectricity; as, thermoelectric currents.

or wires of dissimilar metals joined at their extremities, for producing a thermoelectric current.

An instrument for measuring the strength of an electric current in the heat which it produces, or for determining the heat developed by such a current.

A junction of two dissimilar conductors used to produce a thermoelectric current, as in one form of pyrometer; a thermocouple.

g heat effects, as changes in temperature (hence in length) due to pulsations of the line current in a fine wire connected with the receiver diaphragm.

, connected with an astatic galvanometer, which is very sensibly affected by the electric current induced in the system of bars when exposed even to the feeblest degrees of heat.

A system in which a third rail is used for carrying the current for operating the motors, the rail being insulated from the ground and the current being taken off by means of contact brushes or other devices.

A process of electric welding in which heat is developed by a large current passing through the metal.

A stream; current; flood; as, a tide of blood. "Let in the tide of knaves once more; my cook and I'll provide." Shak.

ends one of these with each corf or tub he has hewn. Token money, money which is lawfully current for more than its real value. See Token, n., 4. -- Token sheet (Print.), the last sheet of each token. W. Savage.

A quantity of explosives anchored in a channel, beneath the water, or set adrift in a current, and so arranged that they will be exploded when touched by a vessel, or when an electric circuit is closed by an operator on shore.
