Hluav taws xob muaj peev xwm zog Ue yog muaj peev xwm zog khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li gravitational muaj peev xwm zog ). Hluav taws xob muaj peev xwm yog cov ib yam , but per charge, Ueq. Ib hluav taws xob muaj peev xwm Qhov sib txawv ntawm ob lub ntsiab lus yog hu ua voltage, V = Ue2q−Ue1q.
Nyob rau hauv txoj kev no, lub zog hluav taws xob muaj peev xwm yog dab tsi?
Chav tsev . The SI chav tsev ntawm hluav taws xob muaj peev xwm zog yog lub joule (lub npe tom qab Askiv tus kws kho mob James Prescott Joule). Hauv CGS qhov system erg yog qhov chav tsev ntawm zog , ua 10−7 J. Kuj tseem siv tau electronvolts, 1 eV = 1.602 × 10−19 J.
Qhov thib ob, vim li cas lub zog hluav taws xob tsis zoo? Tam sim no, peb tuaj yeem txhais qhov hluav taws xob muaj peev xwm zog ntawm ib qho kev them nqi lossis cov nqi faib khoom. Yog li ntawd, ib tug system muaj xws li ib tug tsis zoo thiab ib tug zoo point-zoo li tus nqi muaj ib lub zog tsis zoo . A lub zog tsis zoo txhais tau hais tias kev ua haujlwm yuav tsum tau ua tawm tsam cov hluav taws xob teb hauv kev txav cov nqi sib nrug!
Yog li ntawd, lub peev xwm hluav taws xob txhais li cas?
Ib hluav taws xob muaj peev xwm (tseem hu ua hluav taws xob teb peev xwm , peev xwm poob lub muaj peev xwm electrostatic ) yog tus nqi ntawm kev ua haujlwm yuav tsum tau txav mus rau ib chav tsev ntawm tus nqi los ntawm qhov chaw siv mus rau ib qho chaw tshwj xeeb hauv thaj teb yam tsis muaj kev ua kom nrawm.
Lub peev xwm hluav taws xob tsim tau li cas?
Hauv Circuit Court, ib hluav taws xob teb yog tsim . Qhov no hluav taws xob teb yuam electrons txav. Li no, lub peev xwm lub zog ntawm electron ntog. A peev xwm Qhov sib txawv hauv ib lub voj voog tsuas yog txhais tau hais tias kev ua haujlwm yog ua tiav ntawm electrons los ntawm ib qho hluav taws xob teb raws li lawv dhau los ntawm Circuit Court thiab lawv peev xwm zog hloov.

Vim li cas kuv lub tshuab hluav taws xob tsis tsim hluav taws xob?
Feem ntau ua rau lub tshuab hluav taws xob portable tsis tsim hluav taws xob yog los ntawm kev poob ntawm cov hlau nplaum seem. Generators ua hauj lwm los ntawm kev txav hluav taws xob conductors los ntawm magnetic teb. Koj lub tshuab hluav taws xob tsis muaj hlau nplaum. Thaum cov hlau nplaum seem ploj lawm, lub tshuab hluav taws xob yuav tsis muaj zog thaum pib
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
Dab tsi yog tib yam hauv txhua qhov hluav taws xob hluav taws xob?
Electromagnetic hluav taws xob yog ib hom hluav taws xob uas feem ntau hu ua lub teeb. Feem ntau hais lus, peb hais tias lub teeb mus rau hauv nthwv dej, thiab tag nrho cov hluav taws xob hluav taws xob hluav taws xob mus rau tib qhov ceev uas yog li 3.0 * 108 meters ib ob los ntawm lub tshuab nqus tsev
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
