1. The problem statement, all variables and given/known data
An LC circuit containing an 83.0 [tex]\rm mH[/tex] inductor and a 1.50 [tex]\rm nF[/tex] capacitor oscillates with a maximum current of 0.800 A. Calculate the oscillation frequency of the circuit. 2. Relevant equations [tex]\omega[/tex] = [tex]\frac{1}{\sqrt{LC}}[/tex] [tex]f=2\pi\omega[/tex] 3. The attempt at a solution First I solved for omega [tex]\omega[/tex] = [tex]\frac{1}{\sqrt{.083 H * 1.5*10^{9} F}}[/tex] [tex]\omega[/tex] = 89622.14299 Then, since [tex]f=2\pi\omega[/tex] I just plugged in omega. [tex]f=2\pi*89622.14299[/tex] = [tex]563112.532 Hz[/tex] .. I typed in it, but it came back as incorrect. I looked and I can't find my mistake. I'm pretty sure I converted the units right and am using the right formulas. Can someone check to see if i did any thing wrong? Thanks.

Are you sure about your "relevant equations" ?
