摘要
设计了模拟触电演示仪,在低压直流电条件下,通过操作布偶来生动模拟人体触电的各种情形.学生可从视觉、听觉和触觉多角度真切地体会到触电的反应,达到教育学生安全用电的教学效果.
A demonstration device of electric shock was designed. Under low DC voltage, the electric shock situations were simulated using a toy. Students could experience the electric shock reac- tion from watching, hearing and feeling, and learn how to use electricity safely.
