Resonance Frequency Calculator
Calculate resonance frequency for RLC circuits. Analyze frequency response and circuit characteristics for series and parallel configurations.
Resonance Calculator
How to Use This Calculator
Select Circuit Type
Choose between Series RLC or Parallel RLC circuit configuration. Series circuits have components connected in series, while parallel circuits have components connected in parallel.
Choose Calculation Type
Select 'Resonance Frequency' for basic resonance calculations or 'Frequency Analysis' for detailed frequency response analysis including impedance and phase characteristics.
Enter Component Values
Input the inductance (L) in henries (H) and capacitance (C) in farads (F). These values determine the resonance frequency of your RLC circuit.
Review Resonance Results
The calculator shows resonance frequency (f₀), angular frequency (ω₀), quality factor (Q), and characteristic impedance (Z₀) for your circuit configuration.
Analyze Frequency Response
View the frequency response charts showing magnitude response, impedance vs frequency, and phase response to understand circuit behavior across different frequencies.
Interpret Quality Factor
The quality factor indicates circuit selectivity and bandwidth. Higher Q values mean sharper resonance peaks and narrower bandwidth.
Resonance Frequency Tips
Resonance frequency is the same for both series and parallel RLC circuits: f₀ = 1/(2π√(LC))
Higher quality factor (Q) indicates better frequency selectivity and sharper resonance
Series RLC circuits have minimum impedance at resonance, parallel RLC circuits have maximum impedance
The angular frequency ω₀ = 2πf₀ is often used in circuit analysis and design
Characteristic impedance Z₀ = √(L/C) helps determine circuit matching and power transfer
Frequency response analysis helps understand circuit behavior across the frequency spectrum
Phase response shows how the circuit shifts signal phase at different frequencies
Impedance vs frequency plot reveals the circuit's filtering characteristics
