来自volt,电伏。

1. An automatic voltage regulator ensured a constant output from the generator.

一个自动电压调节器保证了发电机电流输出的稳定。

2. A voltage is then applied across the cell electrodes.

然后给电池的正负电极施加电压.

3. The current lags behind the voltage.

电流滞后于电压.

4. If the input voltage is plus three , it comes out as minus six.

如果输入的电压是+3伏, 那么输出的电压便是-6伏.

5. The units in which we show voltage and current are volt and ampere respectively.

我们用以表示电压和电流的单位分别为伏特和安培。
