电压源和电流源等效条件的推广

Popularization of the Equivalent Conditions of the Voltage Supply and the Current Supply

本文对现行电工学教材中关于电压源等效变换条件的内容进行了推广，对教材中一些不准确的说法给予修正，并推导出不同内阻条件下两个电源的等效变换条件，对电路分析具有重要的意义。

The article popularizes the equivalent transformation conditions of the voltage supply and the current supply in the electrical engineering teaching material. It corrects some inacccurate sayings in the teaching material, reasons out the equivalent transformation conditions of two electric current supplies under the condition of different.internal resistance and holds some significance for the electric ciruit analysis
