SI base unit for the
electric current (symbol:
). 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
metre apart in vacuum, would produce between these conductors a force equal to
newton per
metre of length (9th CGPM, 1948).
