पर्याय
`"voltage"_"primary"/"voltage"_"secondary" gt 1`
`"current"_"primary"/"current"_"secondary" lt 1`
`"number of turns"_"primary"/"number of turns"_"secondary" = 1`
`"power"_"primary"/"power"_"secondary" = 1`

उत्तर
`bb("power"_"primary"/"power"_"secondary" = 1)`
Explanation:
An ideal transformer operates with 100% efficiency, meaning input power equals output power. Therefore, the ratio of `"power"_"primary"/"power"_"secondary"` is always equal to 1, regardless of whether it is a step-up or step-down transformer. The other options describe unequal ratios for voltage and current, but the power must be equal for an ideal transformer.
