1.初中电学教材特点分析。在初中的电学教材内容与目标上,其主要是学生能在认识简单串并联电路的基础上介绍电学基本测量仪表,电流表和电压表,讲解欧姆定律,定量分析研究串并联电路的电流、电压、电阻、电功以及电功率等关系,要求学生将这些基础知识转化为基本技能,即会用伏安法测电阻,会测定小灯泡的实际功率和额定功率,并进一步要求运用这些知识进
1. Junior high school teaching materials characteristics analysis. In junior high school textbooks and objectives of the electrical, mainly students can understand the simple series-parallel circuit based on the introduction of electrical basic measuring instruments, ammeter and voltmeter to explain Ohm’s law, quantitative analysis of series and parallel circuit current, voltage, Resistance, electrical work, and electrical power. Students are required to translate these basics into basic skills that will measure the resistance by voltammetry, determine the actual and nominal wattage of the light bulb, and further require the use of this knowledge
