基本上,這三個單字在很多情況下是通用的,但在詞義上稍有區別:
Inductor: n. (電子)電感 (通 Electrical Inductor)
an electrical device (typically a conducting coil) that introduces inductance into a circuit 一種在電氣回路中的電感感應器件(通常用導電線圈做的)
Coil: n. (電子)線圈
reactor consisting of a spiral of insulated wire that introduces inductance into a circuit 由螺旋形絕緣導線組成、在電氣回路中提供電感的的電抗器
Choke: n. (電子)抗流圈/扼流圈/節流圈 (通 Choke Coil)
a coil of low resistance and high inductance used in electrical circuits to pass direct current and attenuate alternating current 在電氣回路中的一組低電阻、高電感的線圈,用於流通直流電、削減交流
總括而言,Inductor通常是用Coil(金屬絲)做的,而Choke(或Choke Coil)則是Coil的一種。
