However, some circuits require a high Q-factor such as band-pass filters. For a single damped mass-spring system, the Q factor represents the effect of simplified viscous damping or drag, where the damping force or drag force is proportional to velocity. In a series RLC circuit there becomes a frequency point were the inductive reactance of the inductor becomes equal in value to the capacitive reactance of the capacitor. The 2-sided bandwidth relative to a resonant frequency of F0 Hz is F0/Q. Damping and the Natural Response in RLC Circuits. Q factor in a series circuit is: \(Q=\frac{1}{R}\sqrt{\frac{L}{C}}=\frac{\omega _{0}L}{R}=\frac{1}{\omega _{0}RC}\) Where, R: … Q-factor For The Series RLC Circuit calculator uses Quantity Factor=sqrt(Inductance)/(Resistance*sqrt(Capacitance)) to calculate the Quantity Factor, The Q-factor for the series RLC circuit is a dimensionless parameter … The lower the value of this resistance R, the better the quality of the coil. They can be used for modelling resonators. If gain, Apk=1.25 then Q = 1.6 , or ζ = 1/3.2 This is your answer from reading graph. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC. He was evaluating the performance and quality of different coils. Why RLC series circuits with larger Q factor values are considered better? If the Q factor of a laser's cavity is abruptly changed from a low value to a high one, the laser will emit a pulse of light that is much more intense than the laser's normal continuous output.
