Lub coulomb, kuj sau raws li nws cov ntawv luv 'C', yog SI unit rau hluav taws xob. Ib coulomb yog sib npaug rau tus nqi ntawm tus nqi ntawm ib qho ampere ntws rau ib thib ob. Ib coulomb yog sib npaug rau tus nqi ntawm 6.241 x 1018 protons . Tus nqi ntawm 1 proton yog 1.6 x 10-19 C.
Hais txog qhov no, pes tsawg electrons nyob hauv Coulomb?
Ib qho hluav taws xob ib leeg muaj tus nqi ntawm 1.60217733 × 10-19 Coulombs. 6.2415 × 1018 electrons muaj nqi ntawm ib tug Coulomb (1/1.60217733x10-19). 1.6 rau 10 nce mus rau lub zog -19 tsis muaj hluav taws xob muaj nyob hauv ib coulomb ntawm tus nqi.
Tom qab ntawd, lo lus nug yog, Coulomb tus nqi ntau npaum li cas? Ib chav ntsuas hluav taws xob nqi . Pronounced "kool-ahm," ib coulomb (C) yog sib npaug rau ib lub amp ntawm tam sim no ntws los ntawm tus neeg xyuas pib rau ib thib ob. Nws kuj yog sib npaug rau 6.25 quintillion electrons (6.25 X 10 mus rau 18th).
Tsis tas li ntawd, koj yuav ua li cas hloov protons rau coulombs?
Cov lus teb yog 6.241418050181E+18. Peb xav tias koj yog hloov dua siab tshiab nruab nrab ntawm cov nqi hluav taws xob thiab coulomb . Koj tuaj yeem saib cov ntsiab lus ntxiv ntawm txhua chav ntsuas: hluav taws xob lossis coulomb SI derived unit rau hluav taws xob nqi yog lub coulomb . 1 tus nqi hluav taws xob sib npaug rau 1.6022E-19 coulomb.
Muaj pes tsawg coulombs nyob rau hauv 6420 electrons?
Nws yuav muab 1.602176634 × 10−19 coulombs , raws li 2019 SI redefinition ntawm lub coulomb . Hluav taws xob tus nqi tuaj yeem sau luv ua e, piv txwv li 1 hluav taws xob tus nqi tuaj yeem sau ua 1 e.
