Question 18 The following measurements were taken at the origin of an A 1 ring circuit. r1 = 0.4 r2 = 0.67 rn = 0.4 Determine the measured value of resistance at each socket outlet when the ends of the circuit are cross-connected to form a figure 8 GN3 Page 34 (Continuity of ring final circuit) 1. r1 + rn = 0.4 + 0.4 = 0.8/4 = 0.2 2. r1 + r2 = 0.4 + 0.67 = 1.07/4 = 0.267
