means of comparingtwo resistances, h and //; for when there is no current in thebridge cd, their ratio is that of the two resistances a and a, whichcan be adjusted at pleasure. Suppose that the four sides of the quadrilateral are made up ofmetal bars having no appreciable resistance, but that any… … Fig. 320. If we take a = a, then b = b; but the arms a and a may be in anyratio, and the condition of equilibrium is that the resistances of thebranches h and b shall be in the same ratio. The arms a and a areknown as the ratio arms. This arrangement of Wheatstones is frequently compared to…
