# LC Circuit

1. Homework Statement

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. Homework 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.
