初中物理是进入初二新增加的一门学科,才接触物理学习声学、光学学生感觉很有趣,学习兴趣非常浓厚,但一接触电学知识,很多学生看到一大堆公式就很是头痛。但再难的学习内容若我们能够掌握其中的方法、技巧、要领;注重练习,善于总结,成绩的提高也不为难事。按如下方法就可以为尽快掌握初中电学知识节省一些时间。一、认清电路图1、串联、并联初中物理中要求学生掌握最基本的两种连接方式:串联、并联。能否正确分析辨别他们对后面内容的学习至关重要。识别电路的类型,可以从以下几个方面入手:(1)使用定义法识别串并联电路。若电路中的各元件是逐个顺次连接起来的,则电路为串联电路;若各元件
Physics junior high school entrance into physics is a new addition to the first two subjects, only contact with physical learning acoustics, optical students feel very interesting, very interested in learning, but a touch of electrical knowledge, many students see a lot of formulas is a headache. However, difficult to learn content if we can master the methods, skills, essentials; focus on practice, good at summing up, improve the performance is not difficult. By the following method you can save some time as soon as possible to master junior high school electrical knowledge. First, recognize the circuit diagram 1, series, parallel junior high school physics requires students to master the two basic connections: series, parallel. Whether or not they correctly analyze and distinguish what they learn about the rest of the content is crucial. Identify the type of circuit, you can start from the following aspects: (1) Use the definition of law to identify the series-parallel circuit. If the circuit components are sequentially connected one by one, the circuit is a series circuit; if the components
