电场问题是高中物理电学知识中的重点,也是难点,同时也是高考的热点.在静电场这一章里出现了静电力这一新的性质的力,同时还引入了许多陌生的概念,因此在求解静电场问题时,同学们会发现稍不注意就会出错.下面举例分析静电场中的常见错误,希望能够对同学们的学习有所帮助.一、判断电场线分布时的常见错误电场线不是实际存在的线,而是为了形象地描述电场而假想的线.准确识记各种典型的电场线的分布,是求解静
Electric field problem is the focus of high school physics and electrical knowledge, but also difficult, but also the entrance of the hot spot in the electrostatic field appeared in this chapter the electrostatic force of this new character of force, but also introduced many strange concepts, so in When solving electrostatic field problems, students will find that a little careless will make mistakes. The following examples of common mistakes in the electrostatic field, hoping to help students learn. First, determine the distribution of electric field lines when the common error electric field lines Is not the actual line, but the imaginary line in order to vividly describe the electric field.Recognition of the distribution of various typical electric field lines is to solve static
