Amperium (unitas)

Amperium, signo A,. saepe amp imminutum,SI supports only the use of symbols and deprecates the use of abbreviations for units.. est unitas basalis SI fluxus oneris electrici,..Base unit definitions: Ampere . Physics.nist.gov. Accessum 28 Septembris 2010. ex Andrea Maria Ampère appellata, mathematico et physico Francico, qui pater electromagntismi cum Ioanne Christiano Ørsted physico Danico aestimatur.

 Definitio mathematica 
Amperium anno 1948 sic definitum est, postulando constantem magneticum in lege Biot-Savartiana:

. 

Fluxus electricus constans fit si in duobus conductoribus parallelis contineatur, longitudinibus infinitis, quorum diametram neglegere possumus, uno metro subtiliter inter eos, vim in quoque conductore creat magnitudinis 2×10–7 Newtonii per metrum conductoris.
