含有电容器的电路问题历来是令学生头痛的问题,出错率高,这类问题之所以易出错,原因是学生不适当地将电阻电路的解法套用到含电容电路之中,为了防止负迁移的产生,教学中应使学生明确解含电容电路问题应注意以下几点: 1 搞清电容器电容量变化时有关物理量的变化情况 Circuit problems with capacitors have historically caused headaches for students. The error rate is high and the reason why such problems are prone to errors is that students inappropriately apply the solution of a resistive circuit to a capacitor-containing circuit in order to prevent negative migration. Students should be aware of the following points when teaching students to clearly solve problems involving capacitor circuits: 1. To find out the changes in the physical quantities of capacitor capacitance changes
