Zack, I am having some trouble with homework 6, problem 27 from ch 28. I used the equation for resonant frequency (w=(LC)^(-1/2)) to obtain C=1/(LW^2). Plugging in 2*pi and the minimum frequency for W, and the given L, I got an answer that must be right. I payed careful attention to the units as well. f_min = 550*10^3; // 550kHz L =1*10^(-3) // 1mH C_min = 1/(W^2 * L) = 1/((2*pi*550*10^3) * 1*10^(-3)) = 8.373e-11 = 84 pF What did I do wrong?

f_min = 550*10^3; // 550kHz
L =1*10^(-3) // 1mH
C_min = 1/(W^2 * L) = 1/((2*pi*550*10^3) * 1*10^(-3)) = 8.373e-11
= 84 pF
What did I do wrong?
