推荐两道实验测试题江苏省阜宁中学张正太《伏安法测小灯泡电功率》是初中物理中最重要的实验之一，自然就成了中考命题的热点．然而从各省市近几年的中考题中发现，重复课本实验的试题较多；当然也有一些题能注重学生能力的考查，但有时还因未能考虑到灯丝电阻因温度变化... Recommend two experimental test questions Jiangsu Province Suining Middle School Zhang Zhengtai “Volt-ampere measurement bulb electric power” is one of the most important experiments in junior high school physics, naturally became the focus of the test proposition. However, from the examination questions of various provinces and cities in recent years, it has been found that there are more questions in repeated textbook experiments; of course, there are some questions that can focus on the examination of student abilities, but sometimes due to failure to consider the filament resistance due to temperature changes...
