Ib hluav taws xob muaj peev xwm (tseem hu ua hluav taws xob teb peev xwm , peev xwm poob lub electrostatic peev xwm ) yog tus nqi ntawm kev ua haujlwm yuav tsum tau txav mus rau ib chav tsev ntawm tus nqi ntawm qhov chaw siv mus rau ib qho chaw tshwj xeeb hauv thaj teb yam tsis muaj kev ua kom nrawm.
Ib yam li ntawd ib tug yuav nug, dab tsi yog lub peev xwm hluav taws xob hauv cov lus yooj yim?
hluav taws xob muaj peev xwm . n. Kev ua haujlwm ntawm ib chav tsev ntawm tus nqi yuav tsum tau txav tus nqi los ntawm qhov chaw siv mus rau qhov chaw teev tseg, ntsuas hauv joules ib coulomb lossis volts. Qhov zoo li qub hluav taws xob teb yog qhov tsis zoo ntawm gradient ntawm lub hluav taws xob muaj peev xwm.
Vim li cas hluav taws xob muaj peev xwm 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!
Ib tug kuj yuav nug, dab tsi ua rau hluav taws xob muaj peev xwm?
Qhov piv ntawm quab yuam kom them rau sab laug yog hu ua hluav taws xob teb (E). Vim nws yog muab los ntawm ib tug quab yuam, nws yog ib tug vector teb. Cov hluav taws xob muaj peev xwm yog cov hluav taws xob muaj peev xwm lub zog ntawm qhov kev xeem nqi faib los ntawm nws cov nqi rau txhua qhov chaw hauv qhov chaw. Vim nws yog muab los ntawm ib lub zog, nws yog ib tug scalar teb.
Lub peev xwm hluav taws xob 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.

Lub ntsiab txhais ntawm lo lus hluav taws xob hluav taws xob yog dab tsi?
Npe. Cov hluav taws xob hluav taws xob txhais tau tias yog hluav taws xob hluav taws xob uas tso cai rau kev ua haujlwm kom tiav. Ib qho piv txwv ntawm lub zog hluav taws xob yog lub zog los ntawm lub qhov hluav taws xob ntsaws. YourDictionary txhais thiab siv piv txwv
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
