Cov hluav taws xob volt 1.602 × 10−12 1.602 × 10−19 joule ua. Cov ntawv luv MeVindicates 106 (1, 000, 000) hluav taws xob volts ; GeV, 109 (1, 000, 000, 000); and TeV, 1012(1, 000, 000, 000, 000).
Piv txwv li, puas yog ib qho hluav taws xob hluav taws xob zoo ib yam li Volt?
Ib electronvolt yog tus nqi ntawm kinetic zoggained los yog poob los ntawm ib leeg hluav taws xob accelerating los ntawm restthrough ib tug hluav taws xob muaj peev xwm sib txawv ntawm ib tug hluav taws xob invacuum. Cov electronvolt (eV) yog ib chav tsev ntawm lub zog whereasthe hluav taws xob (V) yog SI unit ntawm hluav taws xob muaj peev xwm. The SI unit rau lub zog yog joule (J).
Ib yam li ntawd, lub zog hluav taws xob muaj zog npaum li cas? Hais txog lub zog lub hluav taws xob volt sawv cev: yog tias koj nrawm ib qho kev sib cais hluav taws xob los ntawm ib qho hluav taws xob muaj peev xwm sib txawv ntawm ib qho hluav taws xob , nws yuav nce ib hluav taws xob volt ntawm kinetic zog. Tam sim no ib hluav taws xob yog ajoule per coulomb, yog li ib hluav taws xob volt yog ib lub sijhawm hluav taws xob ib zaug, lossis kwv yees li 1.6 x 10-19joules (J).
Qhov thib ob, qhov voltage ntawm electron yog dab tsi?
Qhov hluav taws xob yog ib qho kev ntsuas ntawm ntau npaum li cas lub zog xa mus them. Ntawm nws qhov yooj yim tshaj plaws, ib hluav taws xob (basiccharge) yog imparted 1.602 × 10−19joules thaum tsiv los ntawm ib qho hluav taws xob muaj peev xwm sib txawv ntawm onevolt. Ib hluav taws xob Tom qab ntawd hais tias muaj lub zog ntawm 1electronvolt.
Dab tsi yog electron volt units?
Nyob rau hauv physics, lub hluav taws xob volt (symbol eV; alsowritten electronvolt ) yog a unit ntawm zog sib npaug rau kwv yees li 1.602 × 10−19 joule (Si chav tsev J). Los ntawm kev txhais, nws yog tus nqi ntawm lub zog tau txais los ntawm tus nqi ntawm ib leeg hluav taws xob tsiv hla anelectric muaj peev xwm sib txawv ntawm ib qho hluav taws xob.
