t of the con-ductors which connect thegalvanometer with the sourceof current. In the center issuspended a short magneticneedle, which swings in ahorizontal plane. Under theneedle is placed a circularscale, graduated in degrees; and at right angles to theneedle is fastened a long, light pointer to… … Fig. 114. 220 ELECTRICITY [§§ 364-366 causes. (See table of natural tangents, page 373.) So ifwe find the angle of deflection for a certain flow, say oneampere, we may determine the strength of any othercurrent which is passed through the instrument by com-paring the tangent of its angle of…
