A Thevenin equivalent can simplify a circuit to one voltage source and one resistor. 戴维南等效可以把电路简化为一个电压源和一个电阻。
To find the Thevenin equivalent seen by the load, remove the load, compute the open-circuit voltage, and then determine the equivalent resistance using source deactivation. 要找负载看到的戴维南等效,先断开负载求开路电压,再通过“关断独立源”等方法求等效电阻。
