Scope and limitations
Ideal AC transformer; excludes losses, saturation, insulation and current ratings. Not applicable to steady DC.
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.
