本文介绍的电容器充、放电过程演示器,利用发光二极管生动、形象、直观地演示电容器充、放电的物理过程,用于课堂教学,可加深学生对电容器储能特性的认识和对充、放电过程的理解,激发学习兴趣,提高课堂教学效果.1电路功能(1)用LED发光排中被点亮的发光二极管数目的多少,定量地显示被测电容器电压的大小(或电荷量的多少).(2)在电容器充、放电过程中,发光二极管被点亮或熄灭的快慢,反映电路中充、放电电流的大小.
This paper describes the capacitor charge and discharge process demonstrator, the use of light-emitting diodes vivid, vivid visual demonstration of capacitor charge and discharge of the physical process for classroom teaching, students can deepen the understanding of the capacitor energy storage characteristics and charge and discharge process (1) With the LED light-emitting row is lit the number of light-emitting diodes, quantitative display of the measured capacitor voltage (or the amount of charge). (2) During charging and discharging of the capacitor, the light emitting diode is lighted or extinguished, reflecting the charging and discharging current in the circuit.
