历年高考物理试题中都有考查学生对电路识别能力的试题,它包含在动态电路分析、故障电路分析、电路设计分析等多种题型中.要正确识别电路,就得对电路结构进行分析.分析电路结构,认识电路的结构特点,是打开电路之门的钥匙.电路分析的主要任务是分析组成电路各元件间的串、并联关系,并画出能明显显示出串、并联关系的简化电路图. 对于较复杂且不规则的电路,更应先将其画成等效的规则电路,以识别电路的连接方式.
In the college entrance examination physics tests, students have to examine the students’ ability to identify the circuit. It is included in dynamic circuit analysis, fault circuit analysis, circuit design analysis and other questions. To correctly identify the circuit, you must analyze the circuit structure. Analyzing the circuit structure and recognizing the structural characteristics of the circuit is the key to opening the circuit. The main task of the circuit analysis is to analyze the serial and parallel relationships among the components that make up the circuit, and to draw a simplified circuit diagram that can clearly show the serial and parallel relationships. For more complex and irregular circuits, they should be first drawn into an equivalent rule circuit to identify the circuit connection.
