在高考中,恒定电流部分的考查主要以闭合电路欧姆定律为核心,讨论闭合电路的外电路的电流、电压及电功率的分配关系,以及电路的局部而引起的变化,而电路的故障分析是上述内容应用的综合体现;另外,此类问题往往与生产、生活实际联系密切,体现当今高考命题的方向,因此电路的故障分析希望引起同学们的足够重视.
In the college entrance examination, the investigation of the constant current part mainly takes the closed circuit Ohm’s law as the core, discusses the distribution relationship of the current, voltage and electric power of the external circuit of the closed circuit, and the change caused by the local part of the circuit. The fault analysis of the circuit is the above The comprehensive application of content applications; In addition, these issues are often closely linked with production and life, reflecting the direction of the current college entrance examination proposition, so the failure analysis of the circuit hopes to arouse enough attention of the students.
