用伏安法测定小灯泡功率实验是初中电学二个重要实验之一,中考考试频率最高,近年来对该实验的考查不拘泥于传统的模式,诸如“填写实验步骤、连实物图”等,而是考查学生的动手能力、发现问题和解决问题的能力,2006年各地中考出现了很多考查上述三种能力的实验故障题,下面分类分析,供大家借鉴. The use of voltammetry to measure the power of a small lamp is one of the two important experiments in junior middle school electricity. The frequency of the examination is the highest. In recent years, the examination of the experiment is not rigidly adhered to the traditional model, such as “filling in the experimental steps, even the physical map” And so on, but to examine the student’s hands-on ability, ability to find problems and solve problems. In 2006, there were a lot of experimental failure questions that examined the above three abilities in the local examinations. The following classification analysis was provided for reference.
