s 3 and 4, no currentflows through the galvanometer, consequently its needle re-mains at zero. If a piece of heavy wire were connected topoints3 and 4 under these conditions, no current would flowthrough it, nor would the current in the circuit be disturbed.If after a balance is so obtained the… … MEASUREMENT OF RESISTANCE. 253 is less than 2 volts, while that between a and 3 is 2 volts.If, in the same manner, the slider at 4 is moved toward d,there is a greater drop across c-4 than a-3, and the currentat 4 divides, part flowing to point 2 by 4-3 through thegalvanometer, and deflecting its…
