摘要
利用平衡电桥和非平衡电桥可以研究光敏电阻的光电特性 ,该实验的原理涵盖电学、光学、半导体物理学等基础知识 .通过实验学生可认识到光敏材料的光电特性 ,并学会一些基本仪器的组装和调试 。
The photoelectric characteristics of photoresistance are studied by using balance electric bridges and non-balance bridges. The principle involves some basic knowledge such as electricity, optics and semiconductor physics. Students can understand the characteristics of photosensitive material very well and learn to assemble and debug the instruments as well as hold a dynamic measurement to translate non-electric quantity into electric quantity.
