istance R. The re-sistance of the connecting wiresis assumed to be negligible.A galvanometer is connectedbetween the sliding contact C andthe connecting point between xand R. The sliding contact ismoved until no current flowsthrough the galvanometer. Thecurrent J^ then flows uniformly through the… … 8. Wheatstones Bridge 17 second rule to the left-hand lower mesh, going round it in a clockwisedirection as indicated by the dotted arrow. This circuit contains no e.m.f.and the current in the galvanometer is zero; therefore I^a + 0 — I^x = 0.Similarly in the right-hand mesh I-fi - I^R +0 = 0. Ct X…
