分析各地中考试卷的试题组成,电学实验在中考的实验题中是每年必考,值得老师和广大学生重视.而列举电学实验中比较典型的几个实验,如“探究电流与电压、电阻的关系”“探究影响电流热效应的因素”“测小灯泡的电阻”“测小灯泡的电功率”等之所以成为中考热点,是因为在题中几乎能集中初中电学的所有重点知识和对学生基本技能的考
Analysis of test papers around the composition of the test, the electrical experiment in the test in the test is an annual test, the teacher and the majority of students deserve attention, while enumerating several typical experiments in electrical experiments, such as “to explore the current and voltage, resistance Relationship ”“ to explore the factors that affect the current thermal effect ”“ measure the resistance of small bulbs ”“ measure the electrical power of small bulbs ”and so the reason why became a hot spot in the exam because almost all of the problems Key knowledge and test of students’ basic skills
