补充资料：电源模型变换
两种电源模型间的等效互换。一个实际的直流电源（如直流发电机、蓄电池等）可以抽象成两种模型：一种由独立电压源与线性时不变电阻元件串联而成(图1); 另一种由独立电流源与线性时不变电导并联而成（图2）。在前一种电源模型中,电阻元件的电阻R称为原电源的内电阻,电压源的电压vs等于原电源的开路电压；在后一种电源模型中，线性时不变电阻元件的电导G称为原电源的内电导,电流源的电流is等于原电源的短路电流。由于它们代表同一个实际电源而有相同的外特性，所以它们能够等效互换。 两种模型等效互换的条件为和在电路计算中，为了计算方便，有时需要把一种电源模型变换成另一种电源模型。把图1的模型换成图2的模型时,后者的电流源电流is必须等于vs,内电导必须等于；反之,把图2的模型换成图1的模型时,后者的电压源电压vs必须等于is，内电阻R 必须等于。
上述变换条件可以推广到交流电路中两种电源模型间的变换和复频域中两种电源模型间的变换。
