The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 m apart in vacuum, would produce between these conductors a force equal to 2 x 10–7 newton per metre of length.

安培是恒定的电流,如果保持在两个无限长的直的平行导体,可以忽略不计的圆形的横截面,和在真空中分开放置1米,将这些导线之间产生的力等于2×10–7牛顿每米长度。

这种情况下,导体通过的电流是1A
