LC Circuit

  1. Mar 29, 2009 #1
    1. The problem statement, all variables and given/known data

    What inductance must be used with a 4.0 µF capacitor to produce a frequency of 10 kHz, which is near the middle of the audible range of frequencies?

    2. Relevant equations

    w = 2pi*f/C=1/(sqrt(T*C)) --->angular fequency
    T= 1/f


    3. The attempt at a solution
    T= 2pi/w ------> w= 2pi/(T/8) = 1/(sqrt(LC))---->(16pi/T)^2=1/(LC)

    This is a new topic for me. I'm not sure if I'm doing it right.

    An inductor with a capacitor does not necessarily produce a frequency, and the combination can undergo electromagnetic oscillations at any frequency.
