安培 - The SI base unit of electric current, 1 ampere is precisely defined as that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross section, and placed 1 metre apart in a vacuum, would produce between these conductors a force of 2 × 10-7newton per metre
国际单位制中的电流基本单位。1安培被精确定义为在真空中两个互相平行、无限长而不管其粗细相距一米的导体间会产生2×10－７牛顿/米之作用力的恒定电流
