电学实验是中学物理实验的重要组成部分,占整个中学物理实验总量的1/3多.教师或学生在进行电学实验的过程中,只有遵守电学实验的操作规程,才能保证人身安全和仪器安全,任何粗心大意都可能酿成事故,造成不必要的损失.中学物理电学实验事故对人体最大的危害是会使实验操作者发生触电事故,其主要原因是违章操作、实验仪器维修不当或实验仪器年久失修造成的,也有教师对有故障的电学仪器进行带电检修时造成的.为了防止在电学实验和带电检修电学仪器时触电事故的发生,笔者分析以下在电学实验
Electrical experiments are an important part of middle school physics experiments, accounting for more than one-third of the total number of physics experiments in middle schools. In the course of electrical experiments, teachers or students can only observe the operating procedures of electrical experiments to ensure personal safety and instrument safety. Any carelessness may lead to accidents and cause unnecessary losses. The greatest harm to the human body in the middle school physical electrical experiment accidents is to cause electric shock accidents to the experimental operators, mainly due to illegal operation, improper maintenance of experimental instruments, or experimental instruments. In the case of disrepair caused by teachers, there are also caused by the teacher’s maintenance of faulty electrical instruments. In order to prevent electric shocks from occurring during electrical experiments and electrification of electrical instruments, the author analyzes the following electrical experiments.
