《恒定电流》为高中电学的基础章节,为历年高考中考点分布的重点区之一。在高考中的典型问题归类如下:1图象问题图象问题一定要弄清横纵坐标的意义以及图线本例身1代表的意义。如图所示,图线①表示某电池组的输出电压-电流关系,图线②表示其的输出功率-电流关系,该电池组的内阻
“Constant Current” is the basic chapter of high school electricity, and it is one of the key areas for the distribution of high school entrance exams over the years. The typical problems in the college entrance examination are categorized as follows: 1 Image Problem The image problem must make sense of the meaning of the horizontal and vertical coordinates and the meaning of the line 1 in this example. As shown in the figure, the graph 1 shows the output voltage-current relationship of a battery pack, and the graph 2 shows the output power-current relationship of the battery pack. The internal resistance of the battery pack
