指针式多用电表是最常用到的一种仪表 ,它的结构和原理涉及了多方面的电学知识。高中学生在课内练习过用微安表组装单量程直流电压表 ,在此基础上让一部分感兴趣的学生研究和学习直流电流表、欧姆表、交流电压表以至简单的多用电表的设计和组装是完全可行的。所需的主要器材是?
Pointer multimeter is one of the most commonly used instruments. Its structure and principle involve various aspects of electrical knowledge. High school students practiced using a microampere meter to assemble a single-volume DC voltmeter during class. Based on this, some interested students study and learn the design and assembly of DC ammeters, ohmmeters, AC voltmeters, and even simple multimeters. Completely feasible. What are the main equipment required?
