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

following nominal values: Ru ¼ 270 U ; R1 ¼ 390 U ; R2 ¼ 560K U; and

R3 ¼ 220K 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 þ10 U ;

vR1 ¼ 20 U; vR2 ¼ 15 U; and vR3 ¼ þ18 U. Calculate the open circuit bridge

output voltage if the bridge supply voltage Vi is 5V.
