测量电功率实验是中考必考的内容,随着新课标的实施,本实验的考查形式不断翻新.考查的知识点主要有对器材的选择、电路的连接、故障的判断、数据的处理及设计实验的能力等,所以该实验一直是中考的热点.下面就2014年江苏省部分大市中考出现的电功率实验题进行进行分析、归类,有以下几种类型.一、电路画图与电功率计算相结合例1(2014·淮安)在“测量小灯泡额定功率”的实验中,选用的器材有:新干电池2节、标有
Measurement of electrical power experiment is the content of the exam will take the test, with the implementation of the new curriculum standard, the test form of continuous innovation.Examination of the knowledge of the main equipment selection, circuit connection, fault judgment, data processing and design experiments So the experiment has been a hot spot in the exam.The following part of the Jiangsu Province in 2014 some of the power market test results appear in the analysis, classification, there are the following types. First, the circuit diagram and the combination of electric power calculation Example 1 (2014 · Huai’an) In the experiment of “measuring the rated power of small bulb”, the selected equipments are: 2 new dry batteries,
