我们知道,电磁感应的电量的表达式可以写成q=n(ΔΦ)/R.但是学生在使用这条表达式时经常出现各种错误.有趣地是,不少高考题专门针对学生出现的错误而编制.现归纳总结学生应用这条表达式时出现的各种错误,并给出相应的 We know that the expression of electromagnetically induced electricity can be written as q = n (ΔΦ) / R. But students often make various mistakes when using this formula. Interestingly, many high test questions are specific to students’ mistakes While the preparation is summarized summarized students apply this expression appeared when a variety of errors and gives the corresponding
