Assumptions & limits
Assumptions & limits
- Source-load resistances, frequency, velocity factor. Returns Ideal transformer impedance and length. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Source resistance (ohms): minimum 1e-12, maximum 1000000000000.0. Load resistance (ohms): minimum 1e-12, maximum 1000000000000.0. Frequency (MHz): minimum 1e-12, maximum 1000000000000.0. Velocity factor: minimum 1e-12, maximum 1.
