高中物理中常见电场类问题分析

Analysis of Common Electric Field Problems in High School Physics

电场类的问题是高中物理中的重点和难点,所含知识点多同时考查十分灵活,给考生们带来了一些困难,为了利于同学们以后的解题思路,笔者在长期的学习做题过程中,总结出了电场中存在的题型以及相关问题。同时在生活中不少地方也应用到了电场,如静电除尘器、电发勘探、静电复印等,可见电场研究对于人们的重要性。本文将以部分电场类题型为例,带领大家一起探究其中的规律和方法。

The problem of electric field is the key and difficult point in senior high school physics.It contains many knowledge points and is very flexible to examine at the same time,which brings some difficulties to the examinees.In order to help students solve problems later,the author summed up the type of questions and related problems existing in electric field in the long-term learning process.At the same time,electric fields are also applied in many places of life,such as electrostatic precipitator,electric power exploration,electrostatic copying,etc.,which shows the importance of electric field research for people.This article will take some electric field questions as examples and lead us to explore the rules and methods.
