An illustration from The four-terminal conductor and the Thomson bridge, 1912, leaf 21
otential terminals 2 and 3 is very approximately the meanof the difference in potential between the points a and a andc and c, regardless of the way the current divides between thetwo wires. Here, unless the resistance from A to B and fromA to B is unnecessarily large, the part of the current… … Fig. 5 576 Bulletin of the Bureau of Standards [v0i.8,No.3 a large change in the current distribution produces only a smallchange in the resistance. If the resistance from a through 2 to c and from a through 3to c; is large in comparison with the resistance of the wires x and y,four more conductors…
