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 ).
Ntxiv mus, dab tsi yog qhov kev sib raug zoo ntawm tam sim no tsis kam thiab voltage?
Ohm txoj cai txhais cov kev sib raug zoo ntawm tus hluav taws xob , tam sim no , thiab tsis kam Nyob rau hauv ib qho hluav taws xob Circuit Court: i = v / r. Cov tam sim no yog ncaj qha proportional rau cov hluav taws xob thiab inversely proportional rau lub tsis kam.
Tsis tas li ntawd, qhov voltage hauv Ohm txoj cai yog dab tsi? 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.
Cov lus nug tseem yog, dab tsi yog qhov kev tiv thaiv tam sim no?
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.
Puas Resistance txo voltage lossis tam sim no?
Hauv luv luv: Resistor txwv qhov ntws ntawm electrons, txo tam sim no . Qhov hluav taws xob los ntawm qhov muaj peev xwm sib txawv ntawm lub zog resistor . Cov lus teb ua lej yog qhov a resistor yog ob lub davhlau ya nyob twg hluav taws xob uas ua raws, lossis koj tuaj yeem hais tias tswj hwm, Ohm txoj cai: V = IR.
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
Tam sim no voltage thiab 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)
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
