高考对电磁学部分的考查始终围绕着“场”与“路”两个方面进行,而《恒定电流》板块不仅与“场”有联系,还与后面的电磁感应及交变电流联系紧密,所以恒定电流承上启下.另外,本章的几个实验又是高考电学命题的主旋律.面对《恒定电流》章节的关键地位,复习时要注意哪些方面呢?
The examination of the electromagnetic part of the college entrance examination has always been conducted in two aspects: “field” and “road”. The “constant current” plate is not only related to the “field” but also to the electromagnetic induction and communication behind it. Variable current is closely related, so the constant current is connected. In addition, several experiments in this chapter are the main theme of the college entrance examination proposition. In the face of the key status of the “Constant Current” chapter, what should we pay attention to when reviewing?
