“测小灯泡功率实验”占中考电学部分实验题分数90%以上.不仅仅是它涉及知识点多,还因为它较全面地考查学生的观察能力,操作能力,创新思维能力,具有较强的综合性.下面就简单介绍这个实验的其他测法. 一、改变测量对象来测量例1 做“测定小灯泡功率”的实验,电源电压为6 V,小灯泡的额定电压为3.8 V.在实 The “small bulb power test” accounts for more than 90% of the test scores of the electrical test. It not only involves more knowledge points, but also because it more comprehensively examines the students’ observation ability, operation ability, and innovative thinking ability, and has strong Comprehensive. The following is a brief introduction to the other tests of this experiment. First, change the measurement object to measure Example 1 Do the experiment of “determine the power of small light bulb”. The power supply voltage is 6 V and the rated voltage of the small light bulb is 3.8 V.
