Tshwj tsis yog tias tus nqi them hla kev hloov pauv magnetic teb, nws peev xwm ntawm txhua qhov chaw tsis nyob ntawm txoj kev coj. Hauv International System of Units (SI), hluav taws xob muaj peev xwm yog qhia nyob rau hauv units ntawm joules ib coulomb (piv txwv li, volts), thiab qhov sib txawv ntawm peev xwm zog yog ntsuas nrog voltmeter.

Tsuas yog li ntawd, hluav taws xob muaj peev xwm thiab nws chav tsev yog dab tsi?

Ib hluav taws xob muaj peev xwm yog tus nqi ntawm cov haujlwm uas yuav tsum tau txav mus los a chav tsev tus nqi zoo los ntawm ib qho kev siv taw tes rau ib qho tshwj xeeb hauv thaj teb yam tsis muaj kev ua kom nrawm thiab nws SI chav tsev yog joule per coulomb I.e Volts.

Tsis tas li ntawd, tus nqi ntsuas yog dab tsi? Chav tsev. Lub SI muab tau los ntawm qhov muaj nuj nqis ntawm hluav taws xob nqi yog coulomb (cim: C). Lub coulomb yog txhais raws li qhov ntau ntawm nqi uas hla hla ntu ntawm ib qho hluav taws xob conductor nqa ib ampere rau ib pliag.

Ib yam li ntawd, qhov twg muaj peev xwm hluav taws xob loj tshaj?

(Rau tib nqi, lub hluav taws xob muaj peev xwm yog loj tshaj ntawm qhov chaw siab dua peev xwm lub zog.) (Lub + nqi yog txav nrog xwm; kev ua hauj lwm tsis tas yuav tsum tau thaum nws txav nrog lub E teb.) (Thaum ib tug + nqi txav ib txwm nyob rau hauv cov kev taw qhia ntawm lub E teb, nws yog txav los ntawm siab PE mus rau tsawg PE.

SI unit ntawm hluav taws xob muaj peev xwm sib txawv yog dab tsi?

Tus qauv metric chav nyob ntawm hluav taws xob muaj peev xwm sib txawv yog volt, luv luv V thiab muaj npe nyob rau hauv kev hwm ntawm Alessandro Volta. Ib Volt yog sib npaug rau ib qho Joule rau Coulomb.
