一、探究规律类例1在探究导体的导电能力与材料关系的实验时,某小组的同学选取了导电能力不受温度影响的材料甲和乙,它们的长度和横截面积均相同,并分别测出了通过它们的电流与它们两端的电压。记录数据如表1和表2所示。 First, to explore the laws of the case 1 In the experiment to explore the conductor’s conductivity and the relationship between the material, a group of students selected materials A and B, the conductivity of which is not affected by temperature, their length and cross-sectional area are the same, and respectively The current through them and the voltage across them were measured. Record data are shown in Table 1 and Table 2.
