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)
