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 … between these points. By the principle of Wheatstonesbridge however, no change of potential between A and B,when the bridge is balanced, can produce a change in thedifference of potential between C and J). ELECTRICITY. 83 Connect the bridge, as in Fig. 38, and adjust for a bal-ance, as in the…
