Question

For an ideal step up transformer:

Options

  • `"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`

Solution

`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.
