An ideal transformer uses the turns ratio to map primary voltage to secondary voltage, so changing secondary turns changes the output scale. The rows use exact, lossless coupling numbers; real transformers include winding resistance, leakage inductance, core loss, saturation, frequency limits, insulation constraints, and voltage measurement uncertainty.
Secondary turns scan the ideal voltage ratio with exact rows. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
Secondary voltage is primary voltage times turns ratio
Each row is a checked ideal transformer with the same primary voltage and primary turns.

Three secondary turn counts scan the voltage ratio
Primary side values stay fixed while secondary turns choose the output voltage.

The displayed voltage is sourced from the checked transformer row
The final row binds turn counts, primary voltage, and secondary voltage in one source object.
