We know that charge is equal to the integral of current times the time. And he knows the current, he knows how much time and then he weighs this.
我们知道电量等于电流,对时间的积分,他知道电流,他也知道时间,然后他测量这个。
Again we have the charge of the nucleus on plus 2, +2 but let's say this time the electron now is going to be very, very close to the nucleus.
对于我们的氦原子,我们有一次得到了原子核电荷量为,但是我们说这次电子。
So hopefully next time we do a formal charge question, we'll get everyone back up to speed.
希望我们下一次做关于形式电荷的问题的时候,大家能够做得快一点。
Next time maybe we'll charge it up before class.
下一次或许我们,会在课前把它充上电。
