a) What is the relationship betwen $Z_X, Z_2, Z_3$ and $Z_4$ when the bridge voltage V=0?

b) Find expressions for $L_X$ and $R_X$ when V=0

a) $\frac{Z_3}{Z_3 + Z_2} = \frac{Z_4}{Z_X + Z_4}$, so $\frac{Z_2}{Z_3}$ = $\frac{Z_X}{Z_4}$

b) Substitution into the formula I found in a)

$R_2(jwC_3 + \frac{1}{R_3}) = jwL_X + R_X + R_4$

Is my thinking here correct?
