Cov cai hauv qab no siv rau hluav taws xob teb kab : Kab pib thiab xaus tsuas yog ntawm tus nqi (pib ntawm + nqi, xaus ntawm - nqi) lossis ntawm Infinity. Kab nyob ze ua ke qhov twg teb muaj zog dua. Cov nqi loj dua muaj ntau dua kab kab pib los yog xaus ntawm lawv.
Tsis tas li ntawd, cov kab hluav taws xob puas tau xaus?
Nyob rau hauv ib tug uniform hluav taws xob teb , cov kab kab yog ncaj, parallel thiab uniformly spaced. Cov hluav taws xob teb kab tsis tuaj yeem tsim cov voj voog kaw, xws li kab yeej tsis pib thiab kawg nyob rau tib nqi. Cov no kab kab ib txwm ntws los ntawm lub peev xwm siab dua mus rau qis dua.
Tsis tas li ntawd, cov kab hluav taws xob puas tuaj yeem pib thiab xaus rau tib tus neeg xyuas pib? Yog hais tias cov electrons nyob rau hauv ib tus thawj coj tau assumed ib tug equilibrium lub xeev, ces lub net quab yuam raws li cov electrons yog xoom. Cov hluav taws xob teb kab los yog pib los yog kawg nyob rau hauv tus nqi thiab nyob rau hauv cov ntaub ntawv ntawm a tus thawj coj , tus nqi muaj nyob rau ntawm nws sab nrauv. Cov kab nthuav tawm ntawm qhov chaw no sab nraud, tsis yog sab hauv.
Ua raws li qhov no saib, cov kab hluav taws xob hluav taws xob nyob qhov twg?
Cov kab hluav taws xob los yog keeb kwm ntawm tus nqi zoo los yog tuaj ntawm infinity, thiab txiav tawm ntawm cov nqi tsis zoo lossis txuas mus rau infinity. Tus naj npawb ntawm teb kab originating los yog txiav tawm ntawm tus nqi yog proportional rau qhov loj ntawm tus nqi ntawd.
Cov kab hluav taws xob nyob qhov twg tawm ntawm qhov zoo kawg nkaus?
Cov cai rau kev kos duab kab kab : Cov kab hluav taws xob pib rau tus nqi zoo thiab kawg ntawm qhov tsis zoo nqi , los yog infinity. Kab yog kos symmetrically tawm mus los yog nkag mus rau a nqi.

Cov kab hluav taws xob ua li cas qhia tias hluav taws xob muaj zog?
Lub zog ntawm cov hluav taws xob hluav taws xob nyob ntawm qhov chaw them nqi, tsis yog ntawm qhov kev xeem nqi. Ib kab tangent mus rau ib kab teb qhia txog kev taw qhia ntawm hluav taws xob ntawm qhov taw tes. Qhov twg cov kab teb nyob ze ua ke, cov hluav taws xob hluav taws xob muaj zog dua qhov uas lawv nyob deb
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
Qhov twg hauv qab no qhia cov piv txwv ntawm tej yam uas hloov hluav taws xob hluav taws xob mus rau thermal zog?
Qhov twg hauv qab no qhia cov piv txwv ntawm tej yam uas hloov hluav taws xob hluav taws xob mus rau thermal zog? Ntxuam thiab cua turbine Toaster thiab chav tso cua sov Lub dav hlau thiab tib neeg lub cev Ntuj lub qhov cub thiab rab
Vim li cas cov kab hluav taws xob ua hluav taws xob yog perpendicular rau equipotential nto?
Txij li cov kab hluav taws xob hluav taws xob taw qhia radiallyaway ntawm tus nqi, lawv yog perpendicular mus rau cov kab hluav taws xob. Lub peev xwm yog tib yam nyob rau hauv txhua txoj kab uas muaj peev xwm, txhais tau hais tias tsis muaj haujlwm yuav tsum tau txav mus los ntawm ib qho ntawm cov kab no
