测定小灯泡的电功率实验是初中物理一个重要的电学实验,由于实验所用的器材较多,同学们对它们的特性没有很好地掌握,加上同学们平时动手操作较少,实验能力不强,因此出现故障较多。为此笔者将本实验中较常出现的故障进行归纳和总结。 The experiment of measuring the electric power of small bulbs is an important electrical experiment in junior high school physics. Due to the large number of equipment used in the experiment, the students did not have a good grasp of their characteristics, coupled with the fact that students usually have less hands-on operations and the experimental ability is not strong. Therefore, more failures occur. For this reason, the author summarizes and summarizes the more frequent failures in this experiment.
