近几年全国高考物理试题,欣喜地发现一些创新题型的出现,可见高考创新命题思路已成为了热点.其中2007年高考物理(上海卷)第16题就是一道具有创新立意的试题,下面以此题为例进行剖析.考题16.某同学设计了如图1(a)所示电路研究电源输出功率变化情况.电源E电动势、内电阻恒定,R1为
In recent years, the national college entrance examination physics test questions, it is pleased to discover the emergence of some innovative questions, showing that the idea of college entrance examination innovation proposition has become a hot spot. The 2007 college entrance examination physics (Shanghai Vol.16) is a question with innovative ideas, the following This question is taken as an example for analysis. Question 16. Some students designed the circuit shown in Figure 1 (a) to study the power output power change situation. The power E electromotive force, constant internal resistance, R1 is
