n parallel with the gal-vanometer G by inserting a metal plug between the metalblocks at a. The switch K connects either the metal tankT or the known resistance R with the battery B. The best method of procedure is to first read the deflec-tion through the insulation resistance of the wire P^witb… … Fig. 1011. same as before. Then, knowing the multiplying power ofthe shunt used, the insulation resistance of the wire may becalculated as in Art. 2522. Example.—In a tangent galvanometer the resistance is 600 ohms;deflection through insulation = 38°; with a shunt of 8 ohms, deflectionthrough…
