复杂电路某一支路电流的求解

Solution About a Certain Branch Current in the Compound Circuit

戴维南定理和电源等效变换在求解过程中使电路形式发生了由复杂电路向简单电路的转变,计算方法因此由难变易。当电路的支路数目较多而节点数目较少时,运用节点电压法是一种更好的选择。

The Thevenin＇s theorem and the power source equivalent transformation caused the circuit form changing from the compound circuit to the simple circuit in the solution process,therefore,the computational method form difficultly to easily.When the leg number of circuit is big and the node point number is small,it is a better choice to use the node voltage method.
