电路的判断是义务教育阶段物理学科电学内容的基础,对于刚刚学习电学的同学,在判断时往往无从下手,极容易出错。笔者在多年的教学中,引导学生对电路元件进行探究,理解元件的实质和电路中的作用,变繁为简,达到正确判断电路的目的,取得一定效果。 Judgment of the circuit is the basis of the electrical content of the physics subject in the compulsory education phase. For those who have just studied electricity, they often have no way to make judgments, and they are very prone to making mistakes. The author in many years of teaching, to guide students to explore the circuit components, understand the essence of the components and the role of the circuit, become simple and complex, to achieve the purpose of correct judgment circuit, to achieve a certain effect.
