eng.resonant-frequency Calculator
Calculates the resonant frequency of RLC circuits and spring-mass systems, and the bandwidth and Q factor. Q factor (resonant frequency / bandwidth) determines the sharpness of resonance — high-Q circuits are used in radio tuners to select narrow frequency bands.
Inputs
L
Opposition to changing current (H). Inductors store energy in a magnetic field and cause voltage spikes when current is interrupted.
C
Ability to store electric charge (F). Capacitors charge quickly and release energy fast. Common values: pF to μF.
R
Opposition to current flow (Ω). V = IR. Resistors in series add; in parallel their reciprocals add.
V
Electric potential difference (V). Drives current through a circuit. Household: 120 V (US) or 230 V (EU/UK).
Results
resonant frequency
Frequency at which the LC circuit naturally oscillates, with energy alternating between inductor and capacitor. F = 1/(2π√LC). Used in radio tuners and oscillators.
Q factor
A dimensionless multiplier applied in the calculation.
bandwidth
The computed width.
inductive reactance
Sample size or count used in the calculation.
capacitive reactance
Sample size or count used in the calculation.
circuit type
The classification or type assigned based on the inputs.
