Then, they passed a high voltage current through the tube to remove any impurities on the inside of the glass.

接着，他们让高压电流通过管子以除去玻璃内部的杂质。

And Ohm's law is about relating voltage, current, and resistance together.

欧姆定律处理电压的相互关系， 电流和电阻。

We also learned about Ohm's Law and the relationship between voltage, current, and resistance.

我们还了解了欧姆定律和 电压、电流和电阻之间的关系。
