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.

流动的电流量以安培计，仅 20 毫安的电流就会导隔膜的控制并停止呼吸。

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， 在你的环路分支上，有一个小小的安培计， 用来测量电流。
