rence is one of refinement, rather than of principle. Having now touched upon the measurement of currents and resistances, let us take upthe one remaining quantity, of the three that are most often referred to by electricians. Suppose that two circuits have precisely the same total resistance, and… … Fig. 7. — Illustrating the Measurement of Resistance. first one, and arranged in tandem fashion, so that the whole current goes throughfirst one of them and then the other. In a case of this kind it is found that the currentin the second circuit will be twice as great as that in the first one. In…
