Homework Help: Resonance in Electrical Circuit

  1. Oct 24, 2008 #1
    (a)Find the frequency at which a 33 uF capacitor has the same reactance as a 33 mH inductor. (b) What is the resonance frequency of an LC circuit made with this inductor and capacitor.

    Well I believe the equation I use is 1 / (2 Pie [tex]\sqrt{}LC[/tex]) but when I use it I come out with a answer very different from the real answer. Am I going about the right way with this problem? Thanks!

    You are using

    [tex]f=\frac{1}{2\pi \sqrt{LC}}[/tex]

    and this is the correct equation. Perhaps recheck your numbers?
