例句
What is the output power at weak signals compared to the optimal load resistor.
在接收弱信号的时候，和最佳负载电阻比较，它的输出功率如何？
In a circuit diagram, on the other hand, a resistor might be oriented horizontally or vertically, and it might appear above, below, or next to the preceding circuit element.
另一方面，在一张电路图表里，一个电阻器可能是水平或者垂直朝向的，并可能在之前电路元素的上面、下面或者旁边。
Because moving charges make currents, and changing magnetic fluxes breed voltages, the new device would generate a voltage from a current rather like a resistor, but in a complex, dynamic way.
因为移动的电荷会产生电流，变化的磁通量会产生电压，新的设备会从电流中产生电压，像电阻一样，不过是以更加复杂、动态的方式。
