    I am having some trouble with the following problem.. The question wants you to convert this circuit to an all series circuit.

    it is also question 5 located here...
    http://www.allaboutcircuits.com/worksheets/ac_sp.html

    the inductor is 500mH. therefore XL = 2∏fL=3.14Ω

    I dont understand how the answer comes up with XL=3.142kΩ

    You got me thinking for a moment there. Just be more careful with your operations:
    X=2 \cdot \pi \cdot 10^3 \cdot 500 \cdot 10^{-3}=1000 \cdot \pi=3.14159kHz

    ohhhhhh f=1kHz

    i missed the K and just thought it was 1Hz.

    thanks
