这种情况下，导体通过的电流是1A
莞城.XiShui(chenboyou) 发表: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。
