Homework Help: Phase angles

  1. Mar 19, 2007 #1
    1. The problem statement, all variables and given/known data

    A resistor of 362 Ohms is connected in series with a capacitor of 50.0 µF capacitance. A sinusoidal signal of f = 11.7 Hz experiences an impedance of 452.836 Ohms. Find the phase shift between the current and voltage at f = 11.7 Hz.

    2. Relevant equations

    I tried using the equation tan = (Xc)/R

    Xc=1/(wC)

    w=2(pi)f

    Z=sqrt(R^2+(Xc)^2)

    Where are you stuck exactly?

    Well, I used all four of those equations (specifically the first one b/c the question is asking for the angle), but when I plugged in my answer, it was wrong.

    tan=(Xc)/R
    theta=tan^-1(Xc/R)=37 degrees

    Hmmm, let me read it again.
