Homework Help: Basic reactance problem

  1. Feb 1, 2010 #1
    1. The problem statement, all variables and given/known data
    What is the reactance of a 0.1-H inductor if the frequency is 60 Hz?


    2. Relevant equations
    z=jwL
    where z is impedance, j is imaginary unit, L is inductance
    x=wL=2pifL
    Z=R+jX


    3. The attempt at a solution
    I know this is pretty basic, but I'm not sure which equation to use. I used the first one and got j6 Ohms, but I'm not sure if impedance and reactance are interchangeable. The other answer choices are the following: infinity Ohms, 37.7 Ohms, or -6j Ohms. Thanks for the help.
