All we need to do is measure the voltage across this resistor.

我们只需要测量一下该电阻两端的电压。

As the voltage across a resistance is changed, the current changes.

电阻的电压变了，电流也变了。

It is necessary to find the current through and voltage across the capacitor.

必须求出该电容上的电流和电压。

As we increase the voltage, we get to a critical value at which it is possible to actually draw electrons across the gap.

当我们增加气压时，我们得到了一个临界值，在这个临界值上,将电子吸引过来是完全有可能的。

That results in a dramatic change in the membrane voltage; the potential across the membrane and that's shown here by this rapid rise in membrane potential.

变化导致了膜电压的剧烈变化,膜电压就是跨膜的电势差,表现为膜电位的迅速上升

Instead, the coil is pulled through the external magnetic field, which induces a voltage across it.

Although the exact mechanism is still not entirely understood, it turns out that illuminating the liquid crystal, applying a voltage across a small region of it, and then turning off the light source causes a small amount of charge to be stored in that region.

ECONOMIST: Just press print

When a voltage is applied across the coating, the window darkens, allowing less light to enter but still permitting a view.
