解决电学的关键是要看清电路图,简化的目的就在于确定电路是串联还是并联,再确定各电表的测量哪个用电器或者电源.简化的两种常见的类型:一种是实物图到电路图的简化,另一种是复杂电路图的简化,直到我们能很清楚地看各电路元件是如何连接的.1.实物图到电路图的简化1.1串联电路若电路是串联电路,可采用“电流路径法”来连接,即在实物图上从电源正极开始,按照电流方向分析,电流通过哪个元件,相应地在电路图中画出
The key to solve the problem of electricity is to see the circuit diagram, the purpose of simplification is to determine whether the circuit is connected in series or in parallel, and then determine which meter or power meter. Simplified two common types: one is the physical map to the circuit diagram Simplify, and the other is the simplification of complex circuit diagram, until we can clearly see how the circuit components are connected .1 physical map to simplify the circuit diagram 1.1 series circuit If the circuit is a series circuit, the “current path method ”To connect, that is, in the physical map from the positive power supply, according to the current direction of analysis, the current through which components, corresponding to draw in the circuit diagram
