ributedbetween the portions ARE and A Q B of the circuit, according to their respective resistances.Hence, by manipulating R,we can arrange the AV be-tween A and B until it equalsthe E.M.F. Cq of the standardcell ; this will be indicatedby the fact that when E^ = e^,then no current will passthrough… … CH. xiT. MEASUREMENT OF RESISTANCES 235 E.M.F. of P gradually alters by polarisation, we can so diminishthe resistance of R as to maintain G undeflected, or E^^ constant. All the above may be regarded as a contrivance for keepingthe two points A and B at a constant AV equal to the E.M.F. eoof the…
