RLC Analyzer – Physics Smoke Tests

Why this page exists

As we expand the simulator (new modes, new plots, new circuit variants), it’s easy to accidentally break a basic formula or sign convention without noticing.

This page runs a few quick “sanity tests” on the physics engine to catch mistakes early. It does not prove the simulator is perfect — it only checks that the most important fundamentals still behave as expected after changes.

What happens when you click “Run tests”

It temporarily sets known, safe example parameters (L, R, f, duty, V).
It calls the same math functions the main app uses (no UI / no canvas needed).
It verifies a few invariants (e.g. no NaN/Infinity, expected trends with frequency/resistance).
It restores your simulator state afterwards.

Result meaning: PASS = all checks succeeded, FAIL = at least one check needs attention.

What these tests cover (today)

Derived helpers: Rtotal() and tau() stay finite and react correctly to parameter changes.
RL sine sanity: edge cases like L→0 behave like a pure resistor; higher frequency increases XL and reduces current.
RL pulse steady-state: duty→0 gives ~0 current; higher resistance reduces current.
Wave engine frame build: the engine returns correctly sized arrays and avoids NaN/Infinity.

We will add more checks over time (power triangle, energy balance, RLC resonance cases, etc.).
