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...

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
