What this calculator covers
The RC / RL / RLC calculator unifies four workflows used in electronics labs and classroom demonstrations. Every computation pushes a detailed step-by-step trail so you can follow the algebra from formula to substituted numbers.
- Compute RC and RL time constants, including the associated cutoff frequency in Hz.
- Analyse two-element divider networks to obtain magnitude |H|, gain in dB, and phase shift.
- Inspect series RLC resonance, reporting ω₀, f₀, quality factor Q, damping ratio ζ, and bandwidth.
- Combine any two resistors, capacitors, or inductors in series or parallel to get the equivalent value.
Step-by-step logging
Each calculation writes the exact substitutions used so students can verify every transformation.

FAQ
- Can I reproduce the acceptance values from datasheets?
- Yes. Try RC low-pass with R = 1 kΩ, C = 100 nF, f = 1 kHz to confirm the magnitude 0.846733, gain −1.445070 dB, and phase −32.141908°.
- Does the RLC mode cover damping and bandwidth?
- Enter R = 20 Ω, L = 10 mH, C = 1 µF to see ω₀ = 10 000 rad/s, f₀ = 1591.549431 Hz, Q = 5, ζ = 0.1, and bandwidth 318.309886 Hz.
