RLC Circuit Calculator

Enter resistance R, inductance L and capacitance C to compute resonant frequency, quality factor and impedance.

Resistance (R)

Inductance (L)

Capacitance (C)

Enter resistance R, inductance L and capacitance C — resonant frequency, angular frequency, quality factor and impedance update automatically.

f₀ = 1 / (2π·√(L·C))

ω₀ = 1 / √(L·C)

Q = (1/R)·√(L/C)

Z (at resonance, series RLC) = R

BW = f₀ / Q = R / (2π·L)

Enter the resistance R (Ω), inductance L (H) and capacitance C (F) of a series RLC circuit.
