transformer
의미: An electrical device that transfers energy between circuits by electromagnetic induction, typically used to increase or decrease alternating voltage.
Transformers are essential components of the electrical power grid. Step-up transformers increase voltage for efficient long-distance transmission, whilst step-down transformers reduce it to safe levels for household use. Small transformers are found in phone chargers and laptop power supplies. The word also has a general meaning of anything that transforms or changes something fundamentally, and is widely known as the name of a popular toy and media franchise.
