An electrical conductor looks the same whether it is live or dead.

电导体不管是否带电，表面看来都是一样的。

Ampacity Ampacity is the safe current-carrying capacity of an electrical conductor in amperes as defined by code.

载流容量载流容量是以安培数来定义导线安全载流能力。

If one end of an electrical conductor is heated while the other is kept cool, a small voltage is created between the two.

如果是一个电导体的一端被加热而另一端仍然是冷的，一个微小的电压就会在二者之间产生。

Don Melrose, also at Sydney, points out that the gas in the middle of the galaxy might already be so strongly ionised, and thus such a good electrical conductor, that current would leak away rather than build up into a concentration like the Snake.

Their method was based on the observation that electrical currents will be induced in a conductor (such as water) when it is faced with a magnetic field that varies over time.
