The causes of voltage drop were analyzed.

分析了电压下降的原因；

I kept on asking myself, why the voltage drop to 3 volts after the fuse.

我一直在问自己，为什么电压下降至3伏特后导火线。

This creates a voltage drop, which can be measured to determine position.

这创建电压降，这可能被测量确定位置。

There is also considerable voltage drop in the consumer's internal wiring.

在用户内部接线中也存在相当的电压降。

They also limit the voltage drop across the igniter during continuity testing.

他们也限制了压降引爆器的过程中的连续性测试。
