I could have chosen my zeropoint of potential energy anywhere I please.
作为重力为0的点,我可以选择这里。

I could have chosen it right here and nothing would change other than that I offset the zeropoint B of my potential energy.
除了会抵消零点,势能什么的,都不会变,但是如果我从A到。

Through electrostatics and examples of low-frequency alternating current and direct-current circuit, the problem of zeropotentialpoint is queried and clarified.
