     Context examples: 

    A unit of electrical, mechanical, and thermal energy (as well as work and quantity of heat) in the SI system, equal to the work done when the point of application of a force of one newton is displaced through a distance of one meter in the direction of the force or the work done when a current of one ampere passes through a resistance of one ohm for one second.

    (Joule, NCI Thesaurus)

    The base units are a choice of seven well-defined units within the International System of Units (Systeme International d'Unites, SI), which by convention are regarded as dimensionally independent and therefore defined in an absolute way without referring to any other units: the meter, the kilogram, the second, the ampere, the kelvin, the mole, and the candela.

    (Base Unit of International System of Units, NCI Thesaurus)

    SI has a short list of base units defined in an absolute way without referring to any other units: the metre, the kilogram, the second, the ampere, the kelvin, the mole, and the candela.

    (International System of Units, NCI Thesaurus)

    If it is the current which changes, then the induced field will generate a potential difference within the coil: if the inductance is one henry a current change of one ampere per second generates a potential difference of one volt.

    (Henry, NCI Thesaurus)
