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.

  1. 01f_0 = 1 / (2pi x sqrt(0.01 x 0.00001)) = 503.3 Hz
  2. 02Damping = 10 / (2 x sqrt(0.01/0.00001)) = 10 / 63.25 = 0.158
  3. 03Q = 31.62 / 10 = 3.16 (underdamped)
