RLC Analyzer – Value Reference

The RLC Analyzer exposes a large number of numerical readouts that describe the electrical behaviour of RL and RLC networks under both sinusoidal and pulsed excitation. This page serves as the complete reference manual for these values.

Every quantity displayed inside the simulator — including energy flow, reactive power, resonance parameters, transient window metrics, and component stress indicators — is documented here with its identifier, units, definition, and physical interpretation. The goal is to make the simulator fully transparent and physically defensible.

Unlike many educational tools that only display a few voltages and currents, the analyzer intentionally exposes a much deeper set of metrics. These include:

  • Energy accounting — verification of energy conservation over a full steady-state period.
  • Window analysis (0→τ) — inspection of transient behaviour within one RL time constant.
  • Reactive energy exchange — tracking how energy oscillates between inductive and capacitive fields.
  • Power-quality quantities — active power, reactive power, and admittance components.
  • Component stress metrics — peak voltages, current slopes, and stored energies.

All metrics are computed at the terminals of an ideal voltage source. The simulator does not include grid impedance or external network models unless explicitly extended. Consequently, the reported quantities represent the intrinsic behaviour of the selected circuit topology itself.

The inventory of values below is extracted automatically from the simulator interface (index.html) while the explanations originate from the documentation registry (docs/value_registry.json). This approach ensures that the documentation remains synchronized with the actual quantities implemented in the analyzer.

Use the search field to locate parameters quickly by name, identifier, symbol, or description.
