Amper

Amper (s taglizit : ampere^[1], s tafrensist : ampère), azamul-is (A), d tigget tidusal n uḍru amestrisiti^[2], kecmen deg unagraw agraɣlan n tiynin seg 1948. Amper d yiwet seg kraḍ tiynin igejdanen n trisiti, akked Ohm (Ω) ed Volt (V)^[3].

Amper yekka-d seg amesfizik afṛansis André-Marie Ampère (seg lqern wis 19)^[1],

Amper d tadwast n uḍru amestrisiti (${\displaystyle I}$)^[4] n uɛeddi n yiwen culum (C) ɣef amenhar (conductor) deg yiwet tasint (s)^[1]:

${\displaystyle Culum(C)=Amper(A).Tasint(s)}$ ${\displaystyle \Longrightarrow }$ ${\displaystyle Amper(A)=Culum(C)/Tasint(s)}$
