tance-arm, as in Figs.38 and 39. If now K2 be closed, there will be a deflec-tion of the galvanometer, which will not be changed inamount by closing Kx, so long as the bridge is balanced.The theory of the method is as follows: The current fromthe battery flows through B, dividing at D, where a part… … Fig. 38. at the same potential. Closing Kx changes the differenceof potential between A and B by making an additionalpath for the current, and thus changing the resistance
