We developed new teaching materials, electrical resistors and capacitors, using carbon nanotube (CNT) paper and carbon fibre (CF) paper to foster students’ creative thinking, thereby deepening and extending learning. Using a CNT-paper electrical resistor, it is possible to elucidate the dependence of the resistance value on the length and width. The resistance value is proportional to the length and inversely proportional to the width of the paper. In the case of the CF-paper capacitor, it is also possible to clarify the dependence of the capacitance value on the area and the distance between papers. The capacitance value is proportional to the areas of the papers and inversely proportional to the distance between them. Based on the results of our experiments using the new teaching materials, we confirmed that the measured values were in good agreement with the values predicted by theoretical calculations. Using these materials, it becomes possible for students to visually and actively learn about electrical resistance and capacitance through experiments by themselves and in discussion with other students, in contrast to the traditional teaching methods practiced in many schools worldwide. We found that teaching methods using these materials are a useful and easy way to teach the basic concepts of resistance and capacitance with geometric factors in classrooms.

我们使用碳纳米管（CNT）纸和碳纤维（CF）纸开发了新的教材，电阻器和电容器，以培养学生的创造性思维，从而加深和扩展学习范围。使用CNT纸电阻器，可以阐明电阻值对长度和宽度的依赖性。电阻值与纸张的长度成正比，与纸张的宽度成反比。在CF纸电容器的情况下，也可以弄清电容值对纸的面积和距离的依赖性。电容值与纸张的面积成正比，与它们之间的距离成反比。根据我们使用新教材的实验结果，我们确认测量值与理论计算预测的值非常吻合。与全球许多学校所采用的传统教学方法相比，使用这些材料，学生可以通过自己进行实验并与其他学生讨论，从而在视觉上和主动地了解电阻和电容。我们发现使用这些材料的教学方法是在课堂上教授具有几何因素的电阻和电容基本概念的有用且简便的方法。与世界各地许多学校所采用的传统教学方法相反。我们发现使用这些材料的教学方法是在课堂上教授具有几何因素的电阻和电容基本概念的有用且简便的方法。与世界各地许多学校所采用的传统教学方法相反。我们发现使用这些材料的教学方法是在课堂上教授具有几何因素的电阻和电容基本概念的有用且简便的方法。
