| Abstract: | 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. |

| Keywords: | photoresistance intensity inner-photoelectric effect balance electric bridge non-balance electric bridge |
