If there is a voltage difference between these conductors, electric charge is stored.
当导体有电压差值时，电荷就能被储存。
Now there is a strange thing because classically you would say, well, if I just have a wire with nothing in it there is no voltage on it.
这是一个奇怪的问题，你可能会说，假如仅仅有一个金属线圈的话，金属线圈内不会有电压。
This is 4, 200 kilometers of high voltage air lines, among which there is a record holder for extra-high voltage (1150 kV).
这是4200千米长的高空高压电线，其中最高电压纪录是1150千伏。
