Then, they passed a high voltage current through the tube to remove any impurities on the inside of the glass.

接着，他们让高压电流通过管子以除去玻璃内部的杂质。

To get that high voltage all of the gels need to contact at the same time.

为了获得那么高的电压，所有的凝胶都需要同时接触。

The first one, the E1 pulse, is a fast, but intense pulse that can quickly induce dangerously high voltages in electrical conductors.

第一种是E1波，它是一种快速而强烈的脉冲，能迅速地在导体中诱发危险的高压。

And if we have a higher voltage, according to Ohm's law, we will get a higher current.

如果我们有更高的电压，根据欧姆定律，我们将获得更高的电流。

But if the second coil has more turns than the first, it'll have a higher voltage, and vice versa.

但是如果第二个线圈的匝数比第一个多， 它就会有更高的电压，反之亦然。

Then, there's the second level – it uses Electric Vehicle Supply Equipment and has a higher voltage (220-240 Volts) to add 10-25 miles per hour of charging.

然后是第二个级别，它使用的是电动汽车供电设备，并且具有较高的电压（220-240伏），每小时充的电可行驶10-25英里。

Now that we know all this, a medic can make sure those defibrillator paddles have the right capacitance, have been given enough charge to create a high voltage, and then CLEAR!

现在我们知道了这一切，医生可以 确认除颤器已准备好使用。
