A gold coin of England current for twenty-one shillings sterling, or about five dollars, but not coined since the issue of sovereigns in 1817. The guinea, so called from the Guinea gold out of which it was first struck, was proclaimed in 1663, and to go for twenty shillings; but it never went for less than twenty-one s…

A large deposit of ore in a lode. Gulf Stream (Geog.), the warm ocean current of the North Atlantic.

A channel or hollow worn in the earth by a current of water; a short deep portion of a torrent's bed when dry.

To run or flow in a broken, irregular, noisy current, as water from a bottle, or a small stream among pebbles or stones. Pure gurgling rills the lonely desert trace, And waste their music on the savage race. Young.

A brass coin bearing the emblem of a harp, -- formerly current in Ireland. B. Jonson.

To clear the throat with an audible sound by forcing an expiratory current of air through the narrow passage between the depressed soft palate and the root of the tongue, thus aiding in the removal of foreign substances.

uit when the electro-motive force induced in this circuit is one volt, while the inducing current varies at the rate of one ampère a second.

tar, the principal altar in a church. -- High and dry, out of water; out of reach of the current or tide; -- said of a vessel, aground or beached. -- High and mighty arrogant; overbearing. [Colloq.] -- High art, art which deals with lofty and dignified subjects and is characterized by an elevated style avoiding all m…

When the rush of water through the main pipe d shuts the valve at a, the momentum of the current thus suddenly checked forces part of it into the air chamber b, and up the pipe c, its return being prevented by a valve at the entrance to the air chamber, while the dropping of the valve a by its own weight allows anothe…

An instrument to measure the velocity of a liquid current by the force of its impact.

, or consisting of, electricity evolved by the action or use of fluids; as, hydrogalvanic currents. [R.]

rding to its construction or use, as tachometer, rheometer, hydrometer, pendulum, etc.; a current gauge.

am to measure the velocity of the water by the inclination given to the thread; a kind of current gauge.

uch idiom. Landor. It is not by means of rules that such idioms as the following are made current: "I can make nothing of it." "He treats his subject home." Dryden. "It is that within us that makes for righteousness." M.Arnold. Gostwick (Eng. Gram. )

The apparent resistance in an electric circuit to the flow of an alternating current, analogous to the actual electrical resistance to a direct current, being the ratio of electromotive force to the current. It is equal to R2 + X2, where R = ohmic resistance, X = reactance. For an inductive circuit, X = 2pfL, where f =…

terial, usually carbon, contained in a vacuum, and heated to incandescence by an electric current, as in the Edison lamp; -- called also incandescence lamp, and glowlamp.

actual contact. Electro-dynamic induction, the action by which a variable or interrupted current of electricity excites another current in a neighboring conductor forming a closed circuit. -- Electro-magnetic induction, the influence by which an electric current produces magnetic polarity in certain bodies near or ar…

t as an induction motor and driven above synchronous speed, thus acting as an alternating-current generator; - - called also asynchronous generator. Below synchronism the machine takes in electrical energy and acts as an induction motor; at synchronism the power component of current becomes zero and changes sign, so th…

A type of alternating-current motor comprising two wound members, one stationary, called the stator, and the other rotating, called the rotor, these two members corresponding to a certain extent to the field and armature of a direct-current motor.

That portion of an electrical apparatus, in which is the inducing charge or current.
