Definition of ampere
- a unit of electric current equal to a flow of one coulomb per second.
- 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 × 10−7 newton per metre
late 19th century: named after A-M Ampere (see Ampère, André-Marie)
