Three transformer rows show turn ratio setting voltage while inverse current keeps ideal power balanced.

Voltage ratio and inverse current ratio keep ideal transformer power balanced. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Two-to-four turns doubles voltage

Turns 2 to 4 carry voltage 4 V to 8 V while currents 4 A and 2 A both close power 16 W.
