If there is a voltage difference between these conductors, electric charge is stored.

当导体有电压差值时，电荷就能被储存。

The average of the difference between these two readings is the desired voltage difference.

这两个测量读数之差的平均值就是我们所希望的电压差。

This supplies 5 volts to pin 13. That creates a voltage difference across the pins of the LED, and lights it up.

这为13脚提供了5伏的电压，正是这个电压使LED灯亮。

So, when the voltage difference between the plates is zero, or when we just don't have the plates there at all, the cathode rays are not bent, they just go right in a straight line, and they can be detected on this screen.

拐弯来测试它们是否带电,当两板之间电压为零，或者根本就,没有这两个板时，阴极射线是一条直线,它可以在屏幕上。

And what we did was he put two detection plates on either side of these cathode rays, and when he put a voltage difference between these two plates, he wanted to see if he could actually bend the rays and test if they're actually charged or not.

但没有实验证明这件事,这就是Thomson所做的，它在阴极射线旁边放两块探测板,他想通过看当他,在两板之间加上电压后,阴极射线是不是会。

And the electrical energy is the product of the charge on the electron times the voltage which is the potential difference through which the electron was accelerated. And so this allows me to, by increasing the voltage, increase the energy on the electron.

电子能量是电子上的电荷数,乘以电压的结果,这是种内在的差距,通过它电子运动得以加速，这也让我，通过增强电压，来增加电子能量。
