人教版的教科书高中《物理必修3-1》第二章恒定电流的第十节实验:测定电池的电动势和内阻的课后习题第2题的命题不够科学,第3题的实验原理图用的是第2题的电路图,题目里给定的数据也有问题。教材题目如下:第2题:用图2-10-6的电路测量一节蓄电池的 PEP textbook High School “Physics compulsory 3-1” The second chapter of the constant current of the tenth experiment: determination of battery electromotive force and internal resistance of the problem after the second question is not enough science, the first three experimental schematic With the second question of the circuit diagram, the subject given the data is also a problem. Textbook topics are as follows: Question 2: Figure 2-10-6 circuit measurement of a battery
