Peb lub hauv paus ntsiab lus ntawm qhov kev qhia no tuaj yeem piav qhia siv cov khoom siv hluav taws xob, lossis tshwj xeeb tshaj yog, tus nqi lawv tsim: Qhov hluav taws xob yog qhov sib txawv ntawm tus nqi ntawm ob lub ntsiab lus. Tam sim no yog tus nqi uas tus nqi ntws. Kev tiv thaiv yog ib yam khoom nyiam los tiv thaiv qhov ntws ntawm tus nqi ( tam sim no ).
Ntawm no, qhov kev sib raug zoo ntawm qhov tam sim no voltage thiab tsis kam?
Cov kev sib raug zoo ntawm tam sim no , voltage thiab kuj yog hais los ntawm Ohm Txoj Cai. Qhov no hais tias lub tam sim no ntws hauv ib lub voj voog yog ncaj qha proportional rau cov ntawv thov hluav taws xob thiab inversely proportional rau lub tsis kam ntawm Circuit Court, muab qhov kub thiab txias tas li.
Ib yam li ntawd, qhov kev tiv thaiv tam sim no yog dab tsi? Kev tiv thaiv yog qhov kev tawm tsam uas ib yam khoom muaj rau kev khiav ntawm hluav taws xob tam sim no . Nws yog sawv cev los ntawm tus tsiaj ntawv loj R.
Yog li ntawd, dab tsi yog tam sim no thiab voltage?
Tam sim no yog tus nqi uas cov nqi hluav taws xob ntws dhau los ntawm ib qho chaw hauv ib lub voj voog. Hauv lwm lo lus, tam sim no yog tus nqi ntws ntawm cov nqi hluav taws xob. Qhov hluav taws xob , tseem hu ua electromotive force, yog qhov sib txawv ntawm tus nqi ntawm ob lub ntsiab lus hauv qhov hluav taws xob. Qhov hluav taws xob yog vim li cas thiab tam sim no yog nws cov nyhuv.
Dab tsi yog qhov voltage hauv Ohm txoj cai?
Ib qho tas mus li hluav taws xob qhov chaw hu ua DC Qhov hluav taws xob nrog a hluav taws xob uas txawv raws sij hawm nrog lub sij hawm hu ua AC hluav taws xob . Qhov hluav taws xob yog ntsuas nyob rau hauv volts, nrog rau ib lub volt raug txhais raws li lub zog hluav taws xob yuav tsum tau yuam ib tug hluav taws xob tam sim no ntawm ib ampere los ntawm ib tug tsis kam ntawm ib tug Ohm.
Pom zoo:
Dab tsi yog qhov kev sib raug zoo ntawm lej ntawm qhov tam sim no tsis kam thiab voltage gizmo?
Ohm txoj cai. Kev sib raug zoo ntawm qhov hluav taws xob, tam sim no, thiab kev tiv thaiv tau piav qhia los ntawm Ohm txoj cai. Qhov kev sib npaug no, i = v / r, qhia peb tias tam sim no, i, ntws los ntawm Circuit Court yog ncaj qha proportional rau qhov voltage, v, thiab inversely proportional to the resistance, r
Tam sim no thiab qhov voltage tsis tu ncua yog dab tsi?
'Cov khoom siv hluav taws xob tsis tu ncua xa cov hluav taws xob ruaj khov thiab sib txawv tam sim no rau LED. Cov khoom siv hluav taws xob tsis tu ncua xa cov tam sim no ruaj khov thiab sib txawv voltage rau LED
Dab tsi yog qhov txawv ntawm qhov tam sim no thiab cov khoom siv tam sim no?
Kev khiav ntawm electrons yog hu ua electron tam sim no. Electrons ntws los ntawm qhov tsis zoo terminal mus rau qhov zoo. Pa tam sim no los yog tam sim no yooj yim, coj zoo li cov neeg nqa khoom muaj txiaj ntsig ua rau tam sim no ntws. Pa tam sim no ntws los ntawm qhov zoo davhlau ya nyob twg mus rau qhov tsis zoo
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
Tam sim no voltage tsis kam yog dab tsi?
Peb lub hauv paus ntsiab lus ntawm qhov kev qhia no tuaj yeem piav qhia siv cov khoom siv hluav taws xob, lossis tshwj xeeb tshaj yog, tus nqi lawv tsim: Voltage yog qhov sib txawv ntawm tus nqi ntawm ob lub ntsiab lus. Tam sim no yog tus nqi uas tus nqi ntws. Resistance yog ib yam khoom nyiam los tiv thaiv tus nqi ntws (tam sim no)
