Resonant Frequency vs Resistance
Series RLC Circuit
f_0 = 1 / (2pi x sqrt(LC))
Damping = R / (2 x sqrt(L/C))
Q = sqrt(L/C) / R
Damping < 1 is underdamped (oscillatory), = 1 is critically damped, > 1 is overdamped.
Example Calculation
R=10 ohms, L=10 mH, C=10 uF.
- 01f_0 = 1 / (2pi x sqrt(0.01 x 0.00001)) = 503.3 Hz
- 02Damping = 10 / (2 x sqrt(0.01/0.00001)) = 10 / 63.25 = 0.158
- 03Q = 31.62 / 10 = 3.16 (underdamped)
