Ib coulomb ib ob yog sib npaug rau ib coul ntawm tus nqi tshaj ib ob . Coulombs ib ob tuaj yeem sau luv ua C / s, piv txwv li 1 coulomb ib ob tuaj yeem sau ua 1 C/s. Koj tuaj yeem sim peb Coulomb cov Kev cai lij choj lub laij lej suav suav quab yuam, nyob deb, lossis nqi.
Hais txog qhov no, Coulomb sib npaug li cas?
Cov coulomb (Symbolized C) yog tus qauv ntsuas hluav taws xob hauv International System of Units (SI). Nws yog ib tug dimensionless kom muaj nuj nqis, sib koom no nam nrog lub mole. Qhov ntau ntawm 1 C yog sib npaug 6.24 x 1018, los yog 6.24 billion. 6.24 x 1018 electrons muaj 1 C ntawm tus nqi.
Kuj Paub, koj yuav hloov coulombs rau amps li cas? Los ntawm kev txhais, ib qho ampere sib npaug rau ib coulomb ib ob. Txhawm rau xam tus naj npawb ntawm cov hluav taws xob hauv ib lub ampere, koj yuav tsum paub tus nqi ntawm ib tus neeg electron hauv coulombs . Qhov ntawd hloov mus rau 1.602 × 10-19 coulombs . Nov yog tag nrho cov ntaub ntawv koj xav tau hloov amps rau electrons per second.
Ib tug kuj yuav nug, yog ib qho amp ib Coulomb ib ob?
Ampere txhais Ampere los yog amp (Symbol: A) yog chav tsev ntawm hluav taws xob tam sim no. Cov Ampere chav tsev muaj npe tom qab Andre-Marie Ampere , los ntawm Fabkis. Ib Ampere txhais tau tias yog tam sim no uas ntws nrog hluav taws xob nqi ntawm ib qho Coulomb ib ob.
Tus nqi ntawm 1 ampere yog dab tsi?
Cov lus txhais yav tom ntej Vim tias ib coulomb yog kwv yees li ntawm 6.2415093 × 1018 theem pib nqi (xws li electrons), ib amper yog kwv yees li sib npaug rau 6.2415093 × 1018 theem pib nqi tsiv dhau ib thaj tsam hauv ib thib ob, los yog kev sib raug zoo ntawm cov tus nqi ntawm cov nqi qis hauv coulombs.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Koj tuaj yeem qhia tau li cas yog tias ob qhov sib npaug sib npaug?
Peb tuaj yeem txiav txim siab los ntawm lawv qhov sib npaug seb puas yog ob kab sib npaug los ntawm kev sib piv lawv cov nqes hav. Yog hais tias cov slopes yog tib yam thiab cov y-intercepts txawv, cov kab yog parallel. Yog tias txoj kab nqes sib txawv, cov kab tsis sib npaug. Tsis zoo li cov kab sib luag, cov kab perpendicular sib tshuam
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Cov coefficients hauv kev sib npaug tshuaj sib npaug qhia koj li cas txog cov reactants thiab cov khoom?
Cov coefficients ntawm kev sib npaug chemicalequation qhia peb cov txheeb ze ntawm moles ntawm reactants thiab cov khoom. Hauv kev daws teeb meem stoichiometric, kev hloov pauv ntawm moles ntawm reactants rau moles ntawm cov khoom raug siv. Hauv kev suav loj, cov molar loj yog xav tau los hloov cov huab hwm coj mus rau moles
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
