纵观近几年高考试题,静电场问题是高考考查的热点,高考对电场知识的考查频率很高,涉及电场线、等势面的特点,电势、电势差、电场力做功和电势能的变化,平行板电容器的电容等概念的理解,以及电势差和电场强度的关系。重点考查基本概念的建立、基本规律的内涵与外延、基本规律的适用条件,考查学生对物理规律的理解、推理、分析问题和解决问题的能力,充分体现了“出活题,
Throughout the college entrance examination examination papers in recent years, the electrostatic field problem is a hot spot for college entrance examination examination, college entrance examination knowledge of electric field frequency is very high, involving the electric field lines, the potential surface characteristics, potential, potential difference, electric field power and potential energy changes, The concept of parallel plate capacitor capacitors, and the relationship between the potential difference and the electric field strength. Focus on examining the establishment of the basic concepts, the connotation and extension of the basic law and the applicable conditions of the basic law, examining the students’ understanding of the laws of physics, reasoning, analyzing problems and the ability to solve problems, fully embodying ”
