hrough the galvanometer. When this is the case,we have R: W = A G: G B, or R = ^ X W. Resistance Coils.—The known resistance W is usuallysupplied by means of a standard set of coils. They are ELECTRIC CURRENTS 267 made of German silver, with their ends soldered to solidpieces of brass on the top of… … Fig. 176. Fig. 177. so meet the corresponding resistance (Figs. 176, 177, and178). A very common way to measure resistance is toplace the battery, galvanometer, and object whose resistanceis to be found in circuit. Note the deflection of the gal-vanometer needle, then put the standard resistance…
