a) State TWO types of AC Bridge. (2 marks) b) List the difference between balance condition and unbalance condition for Wheatstone bridge. (7 marks) c) A similar angle bridge is used for measuring the impedance of a capacitive circuit at a frequency of 2 kHz and has the configuration as shown in Figure Q3 (c). i. Obtain the bridge balance condition for Rx and Cx. ii. (6 marks) Find the equivalent series circuitof the unknown impedance if C = 100uF, R = 15kQ, R 100k and R3 = 50kQ.
