Electrical transformers change AC voltage levels using electromagnetic induction

William Stanley Jr and the Ganz Works developed practical high-voltage power transformers

In 1885, Hungarian engineers at Ganz Works and American inventor William Stanley Jr designed practical alternating current transformers. Transformers step up AC voltage for long-distance power grid transmission with minimal heat loss in cables, then step down voltage safely for domestic household outlets. Transformers function exclusively with alternating current systems.
