where K is the constant of the galvanometer; a, b, R and x are the resistances in the bridge circuit, G is the galvanometer resistance, E is the E.M.F. of the battery. k' == Gb + aG + bR + aR + ab, k" = aRG + RGb + abR, At is the time the galvanometer is in circuit. Where Ax is small compared with x, This last equation was tested experimentally with several galvanometers, using known values for the variation Ax in the fluctuating resistance. It was found that if the At was left constant that
