初中物理课程标准明确指出:家庭电路与我们的生活息息相关,引导学生掌握安全用电的知识,提高学生安全用电的意识,具有实际意义,体现了从生活走向物理,从物理走向社会的新课程理念。为了促使教师落实安全用电的教学内容、检验学生安全用电知识的掌握情况,历年来各地中考物理试卷中大多会有涉及安全用电知识的试题。这类试题往往比较简单, Junior high school physics curriculum standards clearly pointed out that: home circuits and our lives are closely related to guide students to master the knowledge of safe electricity, improve students’ awareness of safe use of electricity, with practical significance, reflects from life to physics, from physical to social new curriculum idea. In order to encourage teachers to implement the teaching content of safe electricity consumption and test the knowledge of students’ safe power consumption, most of the physical examination papers in the middle schools over the years will have questions concerning the knowledge of safety electricity consumption. Such questions are often relatively simple,
