The strength of a current of electricity carried by a conductor or generated by a machine, measured in ampères.

A unit, employed in calculating fall of pressure in distributing mains, equivalent to a current of one ampère flowing through one foot of conductor.

The quantity of electricity delivered in one hour by a current whose average strength is one ampère. It is used as a unit of quantity, and is equal to 3600 coulombs. The terms Ampère minute and Ampère second are sometimes similarly used.

ual to the product of one complete convolution (of a coiled conductor) into one ampère of current; thus, a conductor having five convolutions and carrying a current of half an ampère is said to have 2½ ampère turns. The magnetizing effect of a coil is proportional to the number of its ampère turns.

The unit of electric current; -- defined by the International Electrical Congress in 1893 and by U. S. Statute as, one tenth of the unit of current of the C. G. S. system of electro-magnetic units, or the practical equivalent of the unvarying current which, when passed through a standard solution of nitrate of silver i…

An instrument for measuring the strength of an electrical current in ampères.

itability of a nerve in the region of the positive electrode or anode on the passage of a current of electricity through it. Foster.

A small gold coin formerly current in England; a half angel. Eng. Cyc.

angle between the chord of an aërocurve and the relative direction of the undisturbed air current.

The positive pole of an electric battery, or more strictly the electrode by which the current enters the electrolyte on its way to the other pole; -- opposed to cathode.

, distant from the pole 23º 28min. Thus we say the antarctic pole, circle, ocean, region, current, etc.

The upper, contrary-moving current of the atmosphere over a monsoon.

A lamp with a circular hollow wick and glass chimney which allow a current of air both inside and outside of the flame. Argand burner, a burner for an Argand lamp, or a gas burner in which the principle of that lamp is applied.

To stop; to check or hinder the motion or action of; as, to arrest the current of a river; to arrest the senses. Nor could her virtues the relentless hand Of Death arrest. Philips.

stern, to fall or be left behind. -- To go astern, to go backward, as from the action of currents or winds.

Not simultaneous; not concurrent in time; --opposed to synchronous.

Existing in the atmosphere. The lower atmospheric current. Darwin.

oval of lands or soil from the estate of one man to that of another by an inundation or a current, or by a sudden change in the course of a river by which a part of the estate of one man is cut off and joined to the estate of another. The property in the part thus separated, or cut off, continues in the original owner.…

e retrograde movement of a man or body of men, without changing front. -- Back stream, a current running against the main current of a stream; an eddy. -- To take the back track, to retrace one's steps; to retreat. [Colloq.]

Water turned back in its course by an obstruction, an opposing current , or the flow of the tide, as in a sewer or river channel, or across a river bar.
