    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?
