At a glance:f = 1/(2π√LC); ω = 1/√(LC). Complements lc-resonance and capacitive-reactance.
Formula
f = 1 / (2π·√(L·C)).
$$f = \frac{1}{2\pi\sqrt{LC}}, \quad \omega = \frac{1}{\sqrt{LC}}, \quad Z = \sqrt{\frac{L}{C}}$$How to Use
- Enter L and C.
- The tool returns frequency, period and reactance.
Case Studies
L=1e-3, C=1e-6
f ≈ 5.03 kHz.
FAQ
At resonance?
X_L = X_C, so the LC impedance cancels (ideal).
