Tangent galvanometer
Tangent Tan"gent, n. [L. tangens, -entis, p. pr. of tangere to touch; akin to Gr. ? having seized: cf. F. tangente. Cf. Attain, Contaminate, Contingent, Entire, Tact, Taste, Tax, 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, under Function. Artificial, or Logarithmic, tangent, the logarithm of the natural tangent of an arc. Natural tangent, a decimal expressing the length of the tangent of an arc, the radius being reckoned unity. Tangent galvanometer (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.

Galvanometer Gal`va*nom"e*ter, n. [Galvanic + -meter: cf. F. galvanom[`e]tre.] (Elec.) An instrument or apparatus for measuring the intensity of an electric current, usually by the deflection of a magnetic needle. Differential galvanometer. See under Differental, a. Sine galvanometer, 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.
