Tameddurt
ẓregGeorg Simon Ohm ilul-d ass n 16 meɣres 1789 di Erlangen, deg tmurt n Bavaria. Baba-s, i yellan d amṣebbaɣ n wuzzal.
Deg useggas 1805, Ohm yekcem ɣer tesdawit n Erlangen. Yeqqim din ar useggas 1806, anida yesɛedda akud-ines yettnadi deg tussniwin timatutin.
Syin akkin, yuɣal d aselmad. Seg useggas 1813 ar 1816, yella yesselmed tusnakt di Bamberg. Axeddim-agi yefka-as tagnit ad yesnermi tmusni-ines deg wannar-a.
Seg 1817 ar 1826, yekemmel axeddim-ines n uselmad di Köln. Llan d iseggasen igejdanen i tneflit-ines tamussnakt acku deg tallit-a i yebda anadi-ines ɣef wassaɣen ger uḥric n trisiti, taẓɣelt d tawsna.
Georg Ohm yemmut ass n 6 yulyu 1854 di temdint n Munich. Yeǧǧa-d deffir-s rrḍel meqqren i tussna, ladɣa s usaḍuf-ines yettwassnen s yisem-is, i yuɣalen d llsas i tegmi n tẓuri n trisiti.
Tufin n usaḍuf n Ohm
ẓregDeg useggas 1826, Georg Ohm yebda anadi-ines yesεan azal ameqqran ɣef wassaɣen yellan ger uḥric n trisiti, taẓɣelt d tawsna. Axeddim-agi yewwi-t ɣer yiwet n tufin i yebeddlen udem n tfizikt n trisiti i lebda.
Aseggas kan ḍeffir, deg 1827, yeffeɣ-d s yigmaḍ n unadi-ines. Igmaḍ-a uɣalen d asaḍuf yettwassnen ass-a s yisem n usaḍuf n Ohm, yiwen seg yisuḍaf igejdanen deg tẓuri n trisiti.
Asaḍuf n Ohm yeqqar: Tiɣzi n trisiti tettεeddi deg ukli tettili s waddad yemḥazan ɣer uεekkur n trisiti ger sin n yixfawen n ukli, ma yella taẓɣelt ur tettbeddil ara. S wawalen nniḍen, ma nerna aεekkur, ad ternu yid-s tiɣzi n trisiti s waddad yemgaraden.
Asaḍuf-a yezmer ad yettwaru s tezrirt tamatut: V = I * R, anida V d tussda, I d angi, ma d R d azdu. Tazrirt-a tuɣal d allal agejdan i yimussnawen n trisiti deg uxeddim-nsen n yal ass.
