In the Owen’s bridge shown in below figure, Z1 = 200∠60°, Z2 = 400∠-90°, Z3 = 300∠0°, Z4 = 400∠30°. Then,
(a) Bridge is balanced with given impedance values
(b) Bridge can be balanced, if Z4 = 600∠60°
(c) Bridge can be balanced, if Z3 = 400∠0°
(d) Bridge cannot be balanced with the given configuration
I had been asked this question in examination.
This interesting question is from Problems Involving Coupling Coefficient in chapter Resonance & Magnetically Coupled Circuit of Network Theory
