电学是整个物理学中重要的一块内容，有很多知识可以用科学探究的方法去学习，比如电路、电流与电阻电压的关系、电功率、家用电器等，都能作为科学探究的题材让我们去研究，且可从提出问题、进行猜想与假设、实验设计、通过实验获得证据、检验与评估、表达与交流各个环节上着手进行考题设计．因此这类考题在2005年各地的中考试卷中多次 Electricity is an important part of the entire physics. There is a lot of knowledge that can be learned by scientific inquiry. For example, the relationship between circuits, current and resistance voltage, electric power, and household appliances can all be used as subjects of scientific inquiry. , and proceed from the question design, guess and hypothesis, experimental design, evidence obtained through experiments, testing and evaluation, expression and communication. Therefore, this kind of exam was repeated many times in the mid-test exams in 2005.
