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.

A common mineral embracing many varieties varying in color and in composition. It occurs in monoclinic crystals; also massive, generally with fibrous or columnar structure. The color varies from white to gray, green, brown, and black. It is a silicate of magnesium and calcium, with usually aluminium and iron. Some comm…

Produced by the refraction of light, as seen through water; as, anaclastic curves.

A secondary notch in the pulse curve, obtained in a sphygmographic tracing.

A white or flesh-red mineral, of the zeolite, occurring in isometric crystals. By friction, it acquires a weak electricity; hence its name.

ood or brass, on which this projection of the sphere is made, having a movable horizon or cursor; -- formerly much used in solving some common astronomical problems.

Not changed in form by inversion. Anallagmatic curves, a class of curves of the fourth degree which have certain peculiar relations to circles; -- sometimes called bicircular quartics. -- Anallagmatic surfaces, a certain class of surfaces of the fourth degree.

A distorted or monstrous projection or representation of an image on a plane or curved surface, which, when viewed from a certain point, or as reflected from a curved mirror or through a polyhedron, appears regular and in proportion; a deformation of an image.

A ban or curse pronounced with religious solemnity by ecclesiastical authority, and accompanied by excommunication. Hence: Denunciation of anything as accursed. [They] denounce anathemas against unbelievers. Priestley.

The act of anathematizing, or denouncing as accursed; imprecation. Barrow.

To pronounce an anathema against; to curse. Hence: To condemn publicly as something accursed. Milton.

Fig.: That which gives stability or security; that on which we place dependence for safety. Which hope we have as an anchor of the soul. Heb. vi. 19.

Hence: Firm hold: security.

Something on which one may depend for security; ground of trust.

A silicate of aluminium, occurring usually in thick rhombic prisms, nearly square, of a grayish or pale reddish tint. It was first discovered in Andalusia, Spain.

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.
