Thanks for the response Joel. So if I understand correctly, Q is basically an indicator of how well the LC circuit resonates? Could you think of Q as the inverse of a dampening coefficient? Just about exactly. You'll find the term "damping factor" (sometimes "damping ratio" or "damping coefficient") often used in many situations involving network analysis and control systems, usually represented by the lowercase Greek letter zeta. And it's numerically equal to 1/(2Q), so Q is exactly 1/2 the inverse of the damping factor. When the damping factor is 1 (Q = 0.5), a second order circuit is said to be critically damped.
