电学部分是初中物理的重点内容,主要考察学生电学部分的综合能力,其中电学计算题是中考的必考题目,在各省市中考物理试题中都有体现.日常教学中发现,学生对这一部分的学习有些困难,尤其是面对综合性较强的电学计算题时,存在畏难情绪.考试中也会发现,计算题失分较多.如何才能学会电学,正确解答电学计算题呢?根据多年的教学经验,要快速准确的解答电学计算题,首先要全面掌握知识,并配合一定的习题加以巩固;其次要掌握恰当的解题思路和解题方法.下面对电学计算题的解题过程及解题中应注意的问题做具体分析.第一:掌握基础知识(1)电路判断,要求正确判断:电路是串联还是并联
Electrical part is the focus of junior high school physics, mainly to examine the comprehensive ability of the electrical part of the students, electrical calculation questions in the exam is the compulsory examination questions in the provinces and cities in the physical examination questions are reflected in the daily teaching found that students of this part of Learn some difficulties, especially in the face of a comprehensive strong electrical calculation problems, there is fear mood exam will also find that the calculation of the problem points more.How can we learn electricity, the correct answer to the electrical calculation problem? According to many years Teaching experience, to quickly and accurately solve the electrical calculation problem, we must first fully grasp the knowledge, and with certain exercises to be consolidated; secondly, to master the appropriate problem-solving ideas and problem-solving methods. The following questions on the electrical problem-solving process and Problem-solving should pay attention to the problem to do a specific analysis.First: to master the basic knowledge (1) circuit judgment, requires correct judgment: the circuit is in series or in parallel
