Voltage and Current Sources
电压和电流源
Real voltage sources can be represented as ideal voltage sources in series with a resistance r, the ideal voltage source having zero resistance. Real current sources can be represented as ideal current sources in parallel with a resistance r, the ideal current source having infinite resistance.
实际电压源可以表示为理想电压源与电阻r串联，其中理想电压源的电阻为零。实际电流源可以表示为理想电流源与电阻r并联，其中理想电流源的电阻为无限大。
Such ideal voltage and current sources are used in modeling real circuits with Thevenin's theorem and Norton's theorem.
这样的理想电压源和电流源用于通过诺顿定理和特勒恩定理对实际电路进行建模。
