带电体在电场中具有电势能,电势能可以和其他形式的能量发生相互转化.近几年来关于电场中的能量转化问题在高考试题中多次出现,且学生的得分很不理想针对这种情况很有必要对这一问题进行专题复习,通过分析和归纳电场中常见的功能关系,从而提高学生分析问题、解决问题的能力,最大限度地提高学生的高考成绩. The charged body has potential energy in the electric field, and the potential energy can be transformed with other forms of energy. In recent years, the problem of energy conversion in the electric field has appeared many times in the high test questions, and the student’s score is very unsatisfactory. It is necessary to conduct a special review of this issue and to analyze and summarize common functional relationships in the electric field so as to improve students’ ability to analyze problems and solve problems and maximize students’ college entrance examination results.
