AI overview
A transformer is an electrical device that transfers energy between separate circuits using changing magnetic fields, without requiring a direct connection between them. Transformers matter because they enable efficient power distribution and allow voltage levels to be adjusted for different applications, making modern electrical systems practical.

變壓器（transformer），粤语亦称「火牛」，是應用法拉第電磁感應定律變換（升高或降低）交流电压，但不改变电源频率的电能转换器。 變壓器主要構件包含兩組或以上的線圈（初级线圈、次级线圈）和铁芯，用途是升降交流電的電壓、改變阻抗及分隔電路。電路符號常用T當作編號的開頭。例：T01、T201等。
