Find out phase angle error and unknown capacitance

Find out phase angle error and unknown capacitance




In a modified Desauty bridge measurement the following readings are obtained:



            R1 = 1,000 ?; R2 = 1,000 ?; R3 = 2,000 ?; R4 = 2,000 ?;



            C1 = 1 µF; f = 1,000 Hz; r = 10 ? (resistance of C1)
