中考物理试题中,往往有一道电学综合计算题作为压轴题,其失分率很高.分析原因主要是此类题电路结构复杂,电路状态多变,加之电表较多,使得学生不能正确识别电路,更因解决此类题不仅要深刻理解物理规律并能灵活应 In the examination physics test, there is often a comprehensive electric calculation problem as the finale problem, which has a high rate of loss. The main reason for the analysis is that the circuit structure of such a problem is complicated, the state of the circuit is varied, and the number of meters is large, making it impossible for the student to correctly identify the circuit. , because of solving such problems, we must not only profoundly understand the laws of physics, but also be flexible.
