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 107 J. Kuj tseem siv tau electronvolts, 1 eV = 1.602 × 1019 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.
