电学实验是高考中的热门考点之一,几乎是每年必考,其中电阻的测量又频频出现。考题灵活多变,对学生能力的考查区分度高。在实际教学中发现很多学生看到电学实验往往谈“虎”色变,绕道而行。一般多是先做别的试题,时间允许最后才做实验 Electrical test is one of the hottest test centers in the entrance exam, almost every year will be the test, in which resistance measurements are frequent. The exam is flexible and highly qualified to examine the ability of students. In the actual teaching found that many students see electrical experiments often talk about “tiger” color change, detour. Mostly do more than the first test, the time allowed to do the last experiment
