电路故障题是近几年中考的一个热点,它既是实验教学常见难点,也是学习的弱点.在对电路故障进行分析时,往往感到无从下手,究其原因主要有三方面:一是没有搞清楚电路故障都有哪些情况;二是没有掌握对此类题的分析方法;三是不知道电路出现断路和短路后将会产生哪些现象.下面对电路故障所对应的现象总结归纳给你,让你解题无忧.
Circuit fault problem is a hot spot in recent years, it is both common and difficult experimental teaching, learning weaknesses in the analysis of the circuit failure, often feel unable to start, the reason there are three main reasons: First, did not find out the circuit Second, there is no grasp of the analysis of such problems; Third, do not know the circuit after the circuit and short circuit will produce what phenomenon. The following circuit failure of the corresponding summary of the phenomenon summarized to you, let you Problem-free worry-free.
