be, there will exist apoint, such as D, somewhere on the lower branch which will beat the same potential as B, and therefore the difference of po-tential between A andD will be the same asthat between A andB. If the points Band D are now con-nected by a conduct-or, no current willflow through… … 514 ELECTRICAL RESISTANCE from B to D, the galvanometer will give no indication, since nocurrent flows. If the point D is moved even but slightly to oneside or the other, a current will flow through the galvanometer,since in this case D is no longer at the same potential as B. Assuming now that on…
