论文部分内容阅读
变压器是高中物理中的重要章节之一,是承前启后的一个节点,它既是电磁感应知识在互感现象中的延伸,又是电路知识在这一部分的升华.如果这一部分掌握的不好,必然会影响到《电能的输送》一节的学习.本文拟从一个变压器例题的多解开始并结合自己多年的教学实践,谈谈学生在初学《变压器》一节中存在的困惑和误区.
Transformer is one of the most important chapters in high school physics, and it is a node in the past, which is not only the extension of electromagnetic induction knowledge in the phenomenon of mutual inductance, but also the sublimation of circuit knowledge in this part.If this part is not well mastered, it will inevitably affect To the section of “Conveyance of Electric Energy.” This article intends to start with the multi-solution of a transformer example and combine his years of teaching practice to talk about the confusion and misunderstandings the students have in the “Transformer” section.
