Suppose that the resistive components in the DC bridge shown in Fig. 6.2 have the

following nominal values: Ru ¼ 330 U; R1 ¼ 470 U; R2 ¼ 560K U; and R3 ¼

270K U. The actual value of each resistance is related to the nominal value according

to: Ractual ¼ Rnominal þ vR where vR has the following values: vRu ¼ 5 U; vR1 ¼

þ4 U; vR2 ¼ þ6 U; and vR3 ¼ 9 U. Calculate the open circuit bridge output

voltage if the bridge supply voltage Vi is 12 V.
