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.

Lub ntsuas hluav taws xob ntsuas hluav taws xob ua haujlwm li cas?
Lub taub ntawm lub tester yog kov rau cov neeg xyuas pib (piv txwv li, nws tuaj yeem siv rau ntawm ib lub xov hlau hauv qhov hloov, lossis muab tso rau hauv lub qhov hluav taws xob qhov hluav taws xob). Lub teeb neon siv sij hawm me ntsis tam sim no rau lub teeb, thiab yog li siv tau tus neeg siv lub cev muaj peev xwm mus rau hauv av kom ua tiav lub voj voog
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Lub peev xwm hluav taws xob cuam tshuam li cas rau hluav taws xob teb?
Lub peev xwm hluav taws xob tsuas yog ua haujlwm ua haujlwm ib chav xwb kom txav nws los ntawm ib lub peev xwm mus rau lwm lub peev xwm hauv thaj chaw hluav taws xob. Qhov sib txawv ntawm ob qhov sib txawv equipotentials yog qhov muaj peev xwm sib txawv lossis qhov sib txawv voltage. Electric teb piav txog lub zog ntawm tus nqi
