An unknown capacitance Cu is measured using a deflection bridge, as shown in Fig. 6.10. The components of the bridge have the values: Vs ¼ 10Vrms, C1 ¼ 50mF, R2 ¼ 80 U, and R3 ¼ 20 U. If the output...

An unknown capacitance Cu is measured using a deflection bridge, as shown in

Fig. 6.10. The components of the bridge have the values: Vs ¼ 10Vrms, C1 ¼ 50mF,

R2 ¼ 80 U, and R3 ¼ 20 U. If the output voltage is 3Vrms, calculate the value of Cu.
