Question

If elements in the DC bridge circuit shown in Figure 7.2 have the following values: Ru = 110 ohm, R1 = 100 ohm , R2 = 1000 ohm, R3 = 1000 ohm , Vi = 10 V,

calculate the output
voltage V0, if the impedance of the voltage-measuring instrument is assumed to be
infinite. (Hint: Apply Eqn (7.3).)
