Fórmula
f₀ = 1 / (2π · √(LC)), ω₀ = 2π·f₀, Q = ω₀·L / R, BW = f₀ / Q.
Perguntas Frequentes
Series or parallel?
The formula applies to a series RLC circuit. For parallel, the resonant frequency is identical but Q = R·√(C/L).
What does Q mean?
Quality factor measures damping — high Q gives narrow resonance, low Q gives broad resonance.
