What sets LC resonant frequency?
Both inductance and capacitance determine the ideal natural frequency through their product under a square root.

LC Resonant Frequency Calculator — Frequency, L & C
Calculate ideal LC resonant frequency from inductance and capacitance with common engineering input units.
Result
159.154943 Hz
0.159155 kHz
Ideal LC resonance from 0.01 H and 0.0001 F.
Formula and worked example
f₀ = 1 ÷ (2π√(LC)).
10 mH with 100 µF resonates ideally at about 159.155 Hz.
Assumptions
- This is an ideal lossless LC resonance calculation.
- Real resonant frequency and Q can shift with component tolerance and parasitic resistance/reactance.

Frequently asked questions
Does this calculate Q factor?
No. Q requires loss or resistance information in addition to L and C.
