(a) For the deflection-type AC bridge shown in Fig. 6.10, derive expressions for the

output voltage V0 in terms of the bridge components given for the cases of (i)

Zu and Z1 being inductances Lu and L1, and (ii) Zu and Z1 being capacitances

Cu and C1. Assume that the impedance of the instrument measuring V0 is very

high and can be neglected.

(b) The deflection-type bridge shown in Fig. 6.10 is used to measure an unknown

inductance Lu. If the components in the bridge have the values: Vs ¼ 25Vrms,

L1 ¼ 10mH, R2 ¼ 56 U, and R3 ¼ 33 U, calculate the output voltage V0 if

Lu ¼ 20mH
