Scope and limitations
Idealized SI-unit educational model. Real components, tolerances, losses and safe operating limits require separate verification.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
