Analysis, Electric.
Chemical analysis by electrolytic methods. (See Electrolytic Analysis.)
Analyzer, Electric.
An apparatus used in investigations on electric ether waves. It consists
of a series of parallel metallic wires. When the electric waves have
been polarized, the analyzer will only permit them to go through it
intact, when the plane of vibration of the waves is parallel to its
wires.
Anelectrics.
(a) Bodies which do not become electrified by friction; a term
introduced by Gilbert, now little used, as all bodies develop
electricity under proper conditions by contact action; the reverse of
idioelectrtics.
(b) Also a conductor of electricity, the reverse of a dielectric, q. v.
(See Conductor.)
It will be seen that Gilbert's anelectrics were, after all, the same as
the modern anelectrics, i.e., conductors.
Anelectrotonus.
A term used in medical electricity or electro-therapeutics to indicate
the deceased functional activity induced in a nerve by the proximity of
the anode of an active electric circuit completed through the nerve. The
converse of Kathelectrotonus.
Angle of Declination.
The angle of error of the magnetic needle or compass, measuring the
extent of its deviation from the meridian in any locality. It is the
angle between the plane of the magnetic axis of a magnetic needle free
to take its natural position, and the geographical meridian, the needle
being counterpoised if necessary, so as to hold an absolutely horizontal
position. The deviation is expressed as being east or west, referring
always to the north pole. (See Magnetic Elements.)
Synonym--Variation of the Compass.
[Transcriber's note: See Agonic Line.]
Angle of the Polar Span.
In a dynamo or motor the angle subtended by the portion of a pole piece
facing the armature, such angle being referred to the centre of the
cross-section of the armature as its centre.
