Qee qhov kev qhuab qhia siv tus nqi-rau-ntau qhov piv (Q / m) hloov, uas yog qhov sib txawv ntawm qhov sib txawv ntawm qhov loj-rau-tus nqi. CODATA pom zoo tus nqi rau ib qho hluav taws xob yog Qm=−1.75882001076(53) × 1011 C⋅kg− 1.
tus qauv ntawm tus nqi tshwj xeeb yog dab tsi?
Tus nqi tshwj xeeb ntawm ib qho yog qhov piv ntawm nws cov nqi rau nws qhov hnyav, muab hauv coulombs ib kilogram (C kg–1). Txhawm rau xam cov nqi tshwj xeeb, koj tsuas yog faib tus nqi hauv C los ntawm qhov hnyav hauv kg.
Yuav ua li cas yog chav tsev ntawm cov nqi tshwj xeeb ntawm electron hauv Si system?
Answer: 1.75882001076(53)×1011 C⋅kg−1.
SI unit ntawm tus nqi tshwj xeeb yog dab tsi?
The Coulomb (C) yog SI chav them nqi; Txawm li cas los xij, lwm cov units tuaj yeem siv tau, xws li qhia txog tus nqi ntawm cov nqi qis (e). Chav tsev SI ntawm lub cev muaj nuj nqis m/Q yog kilogram ib coulomb.
Qhov twg yog tus nqi tshwj xeeb tshaj plaws?
Ib qho hluav taws xob muaj qhov tshwj xeeb tshaj plaws ntawm cov khoom. Txhawm rau tuav nws koj yuav xav tau ntau dua rau tib qhov loj lossis lwm qhov qis dua thiab tus nqi tib yam.

Puas yog cov hluav taws xob muaj hluav taws xob zoo?
Ntau yam tseem ceeb, lossis subatomic, cov khoom ntawm cov khoom muaj cov khoom siv hluav taws xob. Piv txwv li, electrons muaj tus nqi tsis zoothiab protons muaj tus nqi zoo, tab sis neutrons muaj pes tsawg tus nqi. Yuav ua li cas them electrons e nqa?
Dab tsi yog qhov hloov pauv hluav taws xob hluav taws xob siv rau?
Transcutaneous hluav taws xob paj hlwb stimulation (TENS) yog ib txoj kev kho mob uas cuam tshuam nrog kev siv hluav taws xob me me. Lub tshuab TENS yog ib qho khoom siv me me, roj teeb ua haujlwm uas tau txuas nrog cov nplaum nplaum hu ua electrodes.
Cov kab hluav taws xob hluav taws xob siab yog dab tsi?
High Voltage Line yog dab tsi? High voltage kis kab xa hluav taws xob hla kev deb. Qhov hluav taws xob siab yuav tsum tau txo qis lub zog poob thaum lub sijhawm nyob deb. Tsis zoo li lwm cov khoom siv hluav taws xob xws li cov nkev, hluav taws xob khaws tsis tau thaum tsis siv.
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
