So, you have a superconducting wire that goes straight down like this and on your loop branch, you have a little ammeter, something that measures current.

所以，你有一根直直向下延伸的超导电线， 在你的环路分，有一个的， 用来测量电流。

The amount of current that’s flowing is measured in amperes, and a current of only 20 milliamps can cause someone to lose control of their diaphragm and stop breathing.

流动的电流量以，仅 20 毫的电流就会导致人失去对隔膜的控制并停止呼吸。
