If there were no voltage on the plates, we would expect everything to be over here in some negative value falling.
如果板子上没有速度,这些可能都在这,都是负值下降的。
And I am able to vary the voltage on the plates making this for argument's sake negative and this for argument's sake positive.
我可以改变两个板子上的电压,为了论证,这个是负电,这个是正电。
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 it is possible to change the voltage on the plates.
在金属板上改变电压是有可能的。
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。
