They need to be low voltage.

它们得是低电压。

Electrons flow from high to low voltage.

电子从高电压流向低电压。

They are represented by high and low voltages.

它们由高电压和低电压表示。

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

火灾警示灯、烟雾警示灯、低压灯。

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

这种细致的过程使得执行器所需的电压显着降低，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， 紧张感降低。

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

就像河流从高压流向低压一样，电荷从高压流向低压。

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，较大电阻器上的电压降高于低电阻器的较低电压降。

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，较低的电压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，晶体管可以在高电压或低电压（例如 5 伏和 0 伏） 之间切换。
