They need to be low voltage.

它们得是低电。

Electrons flow from high to low voltage.

电子从高电流向低电。

They are represented by high and low voltages.

它们由高电和低电表示。

Fire warning lights, smoke warning lights, low voltage lights.

火灾警示灯、烟雾警示灯、低灯。

This meticulous process results in actuators that require significantly lower voltage and can carry more payload.

这种细致的程使得执行器所需的电显着降低，并且可以承载更多的有效负载。

The farther away from the point charge, the lower the voltage.

离点电荷的距离越大， 降低。

Just like a river flows from high elevation to low elevation, electric charge flows from high voltage to low voltage.

就像河流从高流向低一样，电荷从高流向低。

For the same current, the voltage drop across greater resistances is higher than the lower voltage drops for the low resistances.

对于相同的电流，较大电阻器上的电降高于低电阻器的较低电降。

That's because, for the same power, a lower voltage translates to a higher current, and power loss increases proportionally to the square of the current.

这是因为，对于相同的功率，较低的电会转化为较高的电流，并且功率损耗与电流的平方成正比增加。

For example, a computer's main memory is made of transistors that switch between either high or low voltage levels, such as 5 volts and 0 volts.

例如， 计算机的主存储器由晶体管组成，晶体管可以在高电或低电（例如 5 伏和 0 伏） 之间切换。

In a capacitor, these lines run parallel to the plates, and each line that’s closer to the negative plate has a lower electric potential, or a lower voltage.

在电容器中， 这些线与极板平行， 每条线越靠近负极板， 电位越低，即电越低。

In a capacitor, these lines run parallel to the plates, and each line that's closer to the negative plate has a lower electric potential, or a lower voltage.

在电容器中，线路平行于极板，延迟更低 线路最靠近负极板，其力较低。
