Taw qhia rau hluav taws xob volt
Cov hluav taws xob volt, piv txwv li eV, yog chav ntsuas ntawm lub zog. Sawv cev rau lub zog kev tawm tsam ntawm lub tshuab hluav taws xob (qhov tsis zoo nrog lub luag haujlwm ntawm 1.6 × 10-19C) nrawm los ntawm qhov muaj peev xwm sib txawv ntawm 1 volt.
Kev hloov pauv ntawm kev sib hloov ntawm cov hluav taws xob hluav taws xob thiab SI pawg ntawm lub zog hluav taws xob Joule (J) yog 1 eV=1.6021766208 (98) × 10 ^ -19 J
