Definition: Tangent galvanometer
, n. [Galvanic + -meter: cf. F.
An instrument or apparatus for measuring the intensity of an
electric current, usually by the deflection of a magnetic
. See under Differental
, Cosine galvanometer
, Tangent galvanometer
(Elec.), a galvanometer in which the sine,
cosine, or tangent respectively, of the angle through
which the needle is deflected, is proportional to the
strength of the current passed through the instrument.
, n. [L. tangens, -entis, p. pr. of tangere to
touch; akin to Gr. ? having seized: cf. F. tangente. Cf.
, v. t.] (Geom.)
A tangent line curve, or surface; specifically, that portion
of the straight line tangent to a curve that is between the
point of tangency and a given line, the given line being, for
example, the axis of abscissas, or a radius of a circle
produced. See Trigonometrical function

, or Logarithmic tangent
, the logarithm
of the natural tangent of an arc.
, a decimal expressing the length of the
tangent of an arc, the radius being reckoned unity.
(Elec.), a form of galvanometer having
a circular coil and a short needle, in which the tangent
of the angle of deflection of the needle is proportional
to the strength of the current.
Tangent of an angle
, the natural tangent of the arc
subtending or measuring the angle.
Tangent of an arc
, a right line, as ta, touching the arc of
a circle at one extremity a, and terminated by a line ct,
passing from the center through the other extremity o.
