“短板”梳理电场这一章有众多描述电场、电荷特性的物理量,包括场强、电场力、电势、电势能、电势差等,发现并理解这些概念的联系是分析电场问题的基础。2016年考试大纲中选修模块3-1,电场:匀强电场中电势差与电场强度的关系,要求由Ⅰ级变为Ⅱ级。静电感应现象需要分析静电感应的过程,对静电平衡后出现的规律要理解。这类问题一定要看清要求,题目中哪部分电荷是场源,也就是哪个是激发电场的。
“Short Board ” combing the electric field This chapter has a large number of description of the electric field, the physical properties of charge characteristics, including field strength, electric field force, potential, potential energy, potential difference, etc., to discover and understand the connection of these concepts is the basis for the analysis of electric field problems. Elective modules in 2016 exam outline 3-1, electric field: uniform electric potential in the electric field and the relationship between the electric field strength, the request from Ⅰ to Ⅱ level. Electrostatic induction phenomena need to analyze the process of electrostatic induction, to understand the law after the static electricity balance. This kind of problem must see the requirements, which part of the subject charge is the field source, that is which is to stimulate the electric field.
