- ✕Forgetting to convert inductance and capacitance to standard units
常见问题
What determines if a circuit is underdamped, critically damped, or overdamped?
The damping ratio (ζ = R/2 × √(C/L)) determines response: ζ < 1 underdamped, ζ = 1 critical, ζ > 1 overdamped.
What is the quality factor?
Q = ω₀L/R indicates how selective the circuit is; higher Q means sharper resonance and better filtering.
