What can a transformer change its input voltage to?

A transformer is designed to change an alternating current (AC) voltage to a different voltage level, depending on its turns ratio between the primary and secondary coils. This versatility allows the transformer to either step up (increase) or step down (decrease) the voltage.

The correct response indicates that a transformer can achieve any of these voltage modifications. If the primary coil has more turns than the secondary coil, the transformer will reduce the voltage, stepping it down. Conversely, if the secondary coil has more turns than the primary, the transformer will increase the voltage, stepping it up.

While electrical systems often work with standard voltage levels, transformers can be designed for a wide range of voltage transformations, enabling them to meet diverse applications and requirements. This capability makes them critical components in power distribution systems, as well as in various electrical devices and apparatuses where specific voltage levels are needed.
