Weegy: One ampere is defined to be the constant current which will produce an attractive force of 2×10–7 newton per metre of length between two straight, [ parallel conductors of infinite length and negligible circular cross section placed one metre apart in free space.[2][3] The definition is based on Ampère's force law.[4] The ampere is a base unit, along with the metre, kelvin, second, mole, candela and the kilogram: it is defined without reference to the quantity of electric charge. ]
