Power factor

  1. Jan 18, 2005 #1
    A capacitor is connected in parallel with a RL branch and a source providing a frequency omega=(LC)^(-1/2). What is the power factor, knowing that R=1000 Ohm, omega 2000 rad/s and L=1H?

    Its not difficult to find C=0,25 microC and
    XL=2000 Ohm
    XC=2000 Ohm

    but what to do next? How can I calculate Ztot since it's in parallel?

    It's all right :(
    Srry for disturbing.

    You just have to add the impedances in parallel.
