摘　　要：通过计算和实验得出电工学中最基本的规律基尔霍夫定理与戴维南定理和诺顿定理具有等效性,它们对同一线性含电源电路有相同的结果。基尔霍夫定理不但能适合各种线性非线性有源无源电路的计算,且计算出的数据种类更齐全,这是戴维南定理和诺顿定理达不到的。但是戴维南定理和诺顿定理更适合实际测量中对电路的简化,它要比基尔霍夫定理更简便。It shows that the equivalence of the Kirchhofi’s Law and Thevenin/Norton’s theorem through the calculation and experiment,they have the same results on the same linear power circuit.Kirchhofl’s Law can not only suitable lor a variety of the calculation of active or passive circuit lor linear or nonlinear, but also ob-tain a wide variety of data,and then it is impossible lor the Thevenin Norton’s theorem to do this.But the the Thevenin/Norton’s theorem is more suitable lor actual measurement to simplily the circuit,it is more conven-ient than Kirchholl’s Law.
