Current is a fundamental physical quantity, thus its measurement should be based on a fundamental standard set up somewhere (like the standard kilogram or, previously, the standard meter). Instead, the ampere is defined in terms of the force per unit length that exists between two parallel conductors separated by a distance of one meter. Thus it is defined in terms of force and distance. Why is current then not a defined physical quantity instead of a fundamental one????
Re: If current is a fundamental quantity, why is it defined using force?
