警告：如果该值下降到低于5欧姆的整体阻抗系统将下降至危险水平，所以使用时要小心调整这个电阻。
Warning: If the value drops below 5 ohms the overall impedance of the system will drop to dangerous levels so use caution when adjusting this resistor.
这种理论的设备将有一个与源系列零欧姆的输出阻抗。
Such a theoretical device would have a zero ohm output impedance in series with the source.
一个真正的世界电压源具有非常低的，但不为零输出阻抗：通常远小于1欧姆。
