Homework Help: Phase difference!

  1. Oct 13, 2011 #1
    In an RC circuit, two parallel branches, one branch with two resistors in series, and the other with a resistor and a capacitor in series. What is the phase difference between the two parallel branches of an AC signal?

    Have R, C, f. I was told I would be able to calculate this phase difference with;

    psi=atan(I(V)/R(V)), Where "R and I are the real and imaginary parts." and that's all I've got. I know the formal definition of phase comes from
    y=Asin(fx+θ) where psi=-θ/f, but this is apparently not correct. Please any hints/help!
