电学是初中物理重要的内容之一.尽管我们努力教学,但由于对一些细节不太留意,往往会出现一点意想不到的错误,集中起来有以下几点:一、电表连接错误应该说电流表、电压表的连接对我们每个授课教师来说应是最熟悉不过的了.我们有时还会有意识地去训练我们的学生,比如用下题:如图1所示电路,某同学在用电压表 V 测完电阻 Electricity is one of the important contents of junior high school physics. Despite our efforts to teach, due to the lack of attention to some details, there are often some unexpected mistakes. There are the following points: First, the meter connection error should be said that the ammeter, voltage The connection of the table should be the most familiar to each of our instructors. We sometimes consciously train our students, for example with the following questions: The circuit shown in Figure 1 is used by a classmate. Measured resistance
