Base unit ntawm nqi yog coulomb. Ib coulomb sib npaug tus nqi ntawm electrons. Basicunit ntawm tam sim no yog lub ampere (nrog rau cov ntawv luv). Ib ampere sib npaug ib coulomb nqi hla ib qho taw tes hauv qhov chaw dhau ib thib ob.
Raws li txoj cai, koj yuav nrhiav tau tus nqi ntawm qhov tam sim no li cas?
Rau txiav txim tus nqi hluav taws xob nqi uas ntws hauv Circuit Court, koj yuav tsum tau paub qhov tam sim no ntws thiab ntev npaum li cas nws ntws rau. Qhov sib npaug yog: nqi (coulomb, C) = tam sim no (ampere, A) × sij hawm (thib ob, s). Piv txwv li, yog tias a tam sim no ntawm 20 A flows rau 40 s, kev suav yog 20 × 40.
Tsis tas li, tam sim no tus nqi them dhau sijhawm? Tam sim no yog tus nqi uas nqi ntws. Them nqi yuav tsis ntws hauv ib lub voj voog tshwj tsis yog tias muaj qhov anenergy muaj peev xwm tsim kom muaj hluav taws xob muaj peev xwm sib txawv thiab tshwj tsis yog tias tsis muaj lub voj voog kaw los ntawm qhov nqi tuaj yeem txav mus los. 2. Tam sim no muaj kev taw qhia.
Tsuas yog li ntawd, qhov txawv ntawm tus nqi thiab qhov tam sim no yog dab tsi?
Hluav taws xob Them nqi Hluav taws xob yog qhov txav ntawm electrons. Voltage yog qhov sib txawv ntawm tus nqi ntawm ob ntsiab lus. Tam sim no yog tus nqi uas nqi ntws. Resistance yog amaterial tus nyiam los tiv thaiv qhov ntws ntawm nqi ( tam sim no ).
Tus nqi formula yog dab tsi?
Qhov hluav taws xob nqi yog muab los ntawm: Q = I ∙ t. Corresponding SI units: coulomb (C) = ampere (A) ∙ second(s)

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
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
Dab tsi yog qhov sib npaug rau tam sim no muaj peev xwm sib txawv thiab tsis kam?
Equations Equation Symbols Meaning in words I = Δ V R I = dfrac{Delta V}{R} I = RΔV I Kuv yog tam sim no, Δ V Delta V Δ V yog hluav taws xob muaj peev xwm sib txawv, thiab R yog tsis kam Tam sim no ncaj qha proportional rau hluav taws xob muaj peev xwm sib txawv thiab inversely proportional rau kuj
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
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
