Lub tswvyim ntawm hluav taws xob tam sim no

Nyob rau hauv electromagnetism, cov hluav taws xob uas dhau los ntawm txhua ntu cross ntawm tus neeg xyuas pib ib lub sijhawm yog hu ua kev siv hluav taws xob tam sim no. Lub cim rau tam sim no yog kuv, thiab chav tsev yog amperere (a), lossis tsuas yog "a" a "(Andrectoricon, uas tau ua kom muaj txiaj ntsig zoo hauv tshuab hluav taws xob thiab Rau kev ua lej thiab physics. International chav ntawm hluav taws xob tam sim no, amperere, yog muaj npe tom qab nws lub xeem).
[1] Kev coj ua ib txwm muaj ntawm cov nqi pub dawb hauv tus neeg xyuas kev coj ua hauv hluav taws xob hluav taws xob ua hluav taws xob.
[2] Hauv hluav taws xob, nws tau txheej txheem hais tias cov kev taw qhia ntawm kev taw qhia ntws ntawm cov nqi zoo yog qhov kev taw qhia tam sim no. Tsis tas li ntawd, nyob rau hauv engineering, cov kev taw qhia txaus kev taw qhia ntawm cov nqi zoo tseem siv raws li kev taw qhia tam sim no. Qhov ntau ntawm cov tam sim no yog qhia los ntawm tus nqi L ntws los ntawm kev hla hla ntawm tus neeg xyuas pib lub sijhawm, uas yog hu ua qhov siv tam sim no.
[3] Muaj ntau hom caryer nyob rau hauv xwm uas nqa tus nqi hluav taws xob. Piv txwv li: Cov tshuab hluav taws xob sib zog hauv cov neeg hauv khw, Eons hauv cov electrolytes, hluav taws xob thiab ions hauv ntshav, thiab quarks hauv hadrons. Kev txav ntawm cov cab cab no cov ntawv hluav taws xob hluav taws xob.
