If we have a higher z effective, it's pulled in tighter, we have to put in more energy in order to eject an electron, so it turns out that that's why case 2 is actually the lowest energy that we need to put in.
而如果有效核电量更高,原子核的束缚也就更紧,我们不得不输入更多的能量来打出一个电子,这就是第二种情况,所需要输入的,能量更少的原因。
So, this is what goes on in an electrolysis cell, and it works thanks to input energy from a power supply shown here.
所以,这是在一个电化学电池中发生的,它是靠输入的能量工作的,从和这个类似的电源输出的能量。
