"The ampere is defined as that current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 meter apart in a vacuum, would produce between these conductors a force of 2 x 10^-7 newtons per meter of length"
"The ampere is defined as that current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 meter apart in a vacuum, would produce a force of 2 x 10^-7 newtons per meter of length between these conductors "
