Notes
SI base unit. Named after A.M. Ampère (1775-1836), the ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed one meter apart in vacuum, would produce between these conductors a force equal to 2x10-7 newton per meter of length [9th CGPM (1948), Resolution 2 and 7].
