LC / RLC 谐振频率计算器
利用 f₀ = 1 / (2π√(LC)) 求解固有谐振频率、回路电感 L 或调谐电容 C。
Natural LC oscillation frequency in Hertz
Inductance in millihenries (switch inline unit for μH or H)
Capacitance in microfarads (switch inline unit for nF or pF)
分步代入计算过程
In an LC or RLC tank circuit, electrical resonance occurs at the natural frequency f₀ where inductive reactance X_L exactly cancels capacitive reactance X_C: f₀ = 1 / (2 × π × √(L × C)).
