Reading your result
Apply the transformer turns ratio to an AC voltage. The displayed quantity is V. A negative value, when the formula permits one, describes the direction of the difference—not a positive gain.
Limitations
Idealized model using the displayed units; not an engineering safety specification. Confirm the assumptions before using measured data. Ideal AC transformer without losses; not wiring guidance. Numeric results are rounded for display; the calculation does not establish that your chosen inputs represent a realistic or permitted scenario.
