‖n. [ Gr. &unr_;. ] (Greek Antiq.) A woman's headband (sometimes of metal), for binding the front hair. [ 1913 Webster ]

n. [ L. ampelitis, Gr. 'ampeli^tis, fr. 'a`mpelos vine. ] (Min.) An earth abounding in pyrites, used by the ancients to kill insects, etc., on vines; -- applied by Brongniart to a carbonaceous alum schist. [ 1913 Webster ]

‖n. [ NL., fr. Gr. 'a`mpelos vine + 'o`psis appearance. ] (Bot.) A genus formerly including the Virginia creeper. [ Webster 1913 Suppl. ]

n. (Elec.) The strength of a current of electricity carried by a conductor or generated by a machine, measured in ampères. [ Webster 1913 Suppl. ]

{ ‖ } n. [ From the name of a French electrician. ] (Elec.) 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 in water, deposits silver at the rate of 0.001118 grams per second. Called also the international ampère. [ 1913 Webster ]

. (Elec.) A unit, employed in calculating fall of pressure in distributing mains, equivalent to a current of one ampère flowing through one foot of conductor. [ Webster 1913 Suppl. ]

. (Elec.) The quantity of electricity delivered in hour by a current whose average strength is one ampère. It is used as a unit of charge quantity; the Ampere hour is equal to 3600 coulombs. The terms and are sometimes similarly used. [ Webster 1913 Suppl. ]

n. 1. a unit of charge equal to that acquired by the accumulation of one ampere for one second.
Syn. -- coulomb, C [ WordNet 1.5 ]

. (Elec.) A unit of magnetomotive force equal 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 21/2 ampère turns. The magnetizing effect of a coil is proportional to the number of its ampère turns. [ Webster 1913 Suppl. ]

{ ‖ } n. [ Ampère + meter. ] (Physics) An instrument for measuring the strength of an electrical current in ampères. [ 1913 Webster ]

n. [ A corruption of and, per se and, i. e., & by itself makes and. ] A word used to describe the character &unr_;, &unr_;, or &. Halliwell. [ 1913 Webster ]
