摘要
第51届国际物理奥林匹克竞赛实验试题为非理想电容器和发光二极管,测量不同温度下非理想电容器的微分电容,研究LED电压与电流以及芯片温度之间的关系.本文详细介绍了实验试题的内容和竞赛组织者给出的标准解答.
The experiments of the 51th International Physics Olympiad were entitled non-ideal capacitors and LED.Differential capacitance of non-ideal capacitors at different temperatures was measured,and the relationship between LED voltage and current and chip temperature was studied.The contents of the two experimental test questions and the standard solutions given by the competition organizer were introduced in detail.
