A capacitor C, which may be considered to be loss-free, is connected with an inductor to form
Question:
Derive an expression for the quality factor Q1 of the circuit by considering the decay of the oscillation, using the result that the amplitude falls by a factor of e in Q1/π periods.
A quality factor Q2 can also be defined in terms of the circuit parameters as ω0L/R, where ω20 = 1/LC. If C = 2 μF and L = 1 mH, calculate the maximum value of R such that Q1 and Q2 agree to better than 1 part in 103.
