As-sume an open circuit at n in the coil connecting j and c. Thecurrent in traveling from the lamp bank terminal on a to theone on d will take the path a to g, g to m, m to f, f to k, k to other path, a to h, h to b, b to i, i to c, c to j, j to d, isbroken by the open circuit at N. Since no current is flowingthrough this latter path, shown in heavy lines in Fig. 4, no de-flection will be obtained between the connecting segmentsexcept between c and d. When the instrument terminals areplaced on these segments the effect is the same as if they were. r,
