Memory Tip
把 resist（抵抗）想成阻挡电流的动作，-or 结尾像是“阻者”：电阻器就是挡住电流的元件。
Context & Register
语域：neutral 常见场景：电子产品说明书、电路设计文档、物理或电子技术教材 该词是电子与电气领域的技术名词，通常用于技术文档、教材和电路相关讨论；在一般日常口语中较少出现。
Pronunciation & Spelling
Transistor shares the exact spelling ending '-istor' and the stress pattern, so it rhymes and looks alike. Blister, sister, mister, and twister rhyme (same /ɪstə/ sound) despite the '-ister' spelling. Minister looks similar in spelling but stresses the first syllable, so it does not rhyme.
