同学们在课外经常做一些小实验,可以巩固所学物理知识,提高学习兴趣,培养分析问题、解决问题和实际操作的能力.在继电器控制电路中接入对光或温度敏感的元件就可以实现光或温度自动控制.现举一例供同学们课外进行动手实验. 实验题目:光控灯.电路图如图1.

Students often do some small experiments outside class, they can consolidate the physics knowledge they learned, increase their interest in learning, and develop the ability to analyze problems, solve problems, and perform practical operations. Connecting light or temperature-sensitive components in the relay control circuit can be achieved. Automatic control of light or temperature. Now give an example for students to conduct hands-on experiments outside class. Experiment subject: light control lamp. Circuit diagram shown in Figure 1.
