Which of the following is NOT the correct representation of the balanced condition of AC bridges?

A

$$ I_1 = I_3, I_2 = I_4 $$

B

$$ \mid Z1 \mid + \mid Z4 \mid = \mid Z2 \mid + \mid Z3 \mid $$

C

$$ \theta_1 + \theta_4 = \theta_2 + \theta_3 $$

D

$$ \mid Z1 \mid \mid Z4 \mid = \mid Z2 \mid \mid Z3 \mid $$
