测小灯泡的功率是中考经常出现的题目,也是考生失分率较高的题型.现将有关这类题目的题型及解法总结如下,供同学们参考.一、常规型用伏安法测灯泡的电功率,所给器材完整.可以按照物理教材中的方法去做,此处不再重述.二、电压表量程过小型题目特点:所给电压表的量程小于灯泡的额 Measuring the power of small bulbs is often the subject of the exam, and it is also a question type with higher exam scores. The question types and solutions for these questions are summarized below for reference by students. 1. Conventional voltammetry The electric power of the bulb is measured, and the equipment is provided. It can be done according to the methods in the physics textbook. It will not be repeated here. II. The voltmeter has a small scale. The feature: The range of the given voltmeter is smaller than the amount of the bulb.
