Qhov tsis yog Qhov sib txawv ntawm electrostatic potentialenergy thiab hluav taws xob (al) muaj peev xwm zog . Cov hluav taws xob muaj peev xwm ntawm ib lub ntsiab lus yog kev ua hauj lwm ua los ntawm anexternal quab yuam nyob rau hauv tsiv unit zoo nqi los ntawm ib tug arbitrarilychosen xoom ntawm peev xwm (feem ntau infinity) mus rau qhov point.

Ua li no, txhais li cas los ntawm electrostatic peev xwm?

Ib hluav taws xob muaj peev xwm (tseem hu ua hluav taws xob teb peev xwm , peev xwm poob orth muaj peev xwm electrostatic ) yog tus nqi ntawm kev ua haujlwm uas 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 tau ua kom nrawm.

Ib yam li ntawd, koj txhais li cas los ntawm hluav taws xob muaj peev xwm? Hluav taws xob muaj peev xwm zog , los yog electrostaticpotential zog , yog a muaj peev xwm zog (ntsuas injoules) uas tshwm sim los ntawm kev saib xyuas Coulomb rog thiab koom nrog kev teeb tsa ntawm ib qho tshwj xeeb ntawm cov ntsiab lus hauv ib qho kev teev tseg.

Xav txog qhov no, qhov txawv ntawm hluav taws xob muaj peev xwm thiab hluav taws xob muaj peev xwm hluav taws xob yog dab tsi?

Hluav taws xob muaj peev xwm zog Ue yog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (likegravitational muaj peev xwm zog ). Hluav taws xob muaj peev xwm yog tib yam, tab sis ib tus nqi, Ueq. (Piv tau thaum sib piv txawv cov ntsiab lus.)

Unit ntawm peev xwm yog dab tsi?

Tus qauv metric chav tsev ntawm hluav taws xob peev xwm Qhov txawv yog qhov volt, luv luv V thiab lub npe hu ua inhonor ntawm Alessandro Volta. Ib Volt yog sib npaug rau ib Joule perCoulomb. Vim hluav taws xob peev xwm qhov txawv yog qhia units ntawm volts, nws yog qee zaum hu ua thevoltage.
