摘要
基于生活中的自感现象,该装置改进了传统的日光灯原理演示仪,通过对比使学生更加容易理解镇流器的作用.另外,为了模拟生活中无轨电车产生电火花的现象,创新性地设计并制作了模拟无轨电车产生电火花的装置,使学生能够更加深刻地理解生活中的自感现象.
Based on the phenomenon of self-inductance in life,the device improved the traditional fluorescent lamp principle demonstrator,which made it easier for students to understand the function of the ballast.Besides,in order to simulate the trolley produces the phenomenon of the electric spark,the device that simulates the electric spark from the trolley was creatively designed and produced least students could understand more deeply about the phenomenon of self-perception in life.
