Ib qho hluav taws xobntws thaum electrons txav los ntawm tus neeg xyuas pib, xws li cov hlau hlau. Cov electrons txav tuaj yeem sib tsoo nrog cov ions hauv cov hlau. Qhov no ua rau nws nyuaj rau qhov tam sim no ntws, thiab ua rau tsis kam.
qhov kev tawm tsam hauv Circuit Court tuaj qhov twg?
Qhov kev tiv thaiv ntawm ib lub xaim yog ncaj qha proportional rau nws qhov ntev thiab inversely proportional rau nws hla ntu ntu. Kuj tseem nyob ntawm cov khoom siv ntawm tus neeg xyuas pib. Saib resistivity. Qhov tsis kam ntawm tus neeg xyuas pib, lossis cov khoom siv hluav taws xob, feem ntau nce nrog qhov kub thiab txias.
Koj txhais li cas los ntawm kev tawm tsam?
Resistance yog ntsuas ntawm qhov kev tawm tsam rau tam sim no ntws hauv hluav taws xob. Kev tiv thaiv yog ntsuas hauv ohms, cim los ntawm Greek tsab ntawv omega (Ω). … Tag nrho cov ntaub ntawv tiv thaiv tam sim no ntws mus rau ib qib.
Dab tsi ua rau cov resistor tsis kam?
Ntawm qib microscopic, electrons txav los ntawm tus neeg xyuas pib sib tsoo (lossis cuam tshuam) nrog cov khoom uas tus neeg xyuas pib (hlau) ua. Thaum lawv sib tsoo, lawv hloov kinetic zog. Qhov no ua rau muaj kev tawm tsam. Lub zog xa mus ua rau cov resistor kom sov.
kev tiv thaiv thiab kev tiv thaiv li cas?
Rau cov khoom siv hluav taws xob, qhov kev tiv thaiv ntawm cov khoom siv yog inversely proportional to the area of cross-section and directly proportional to the length of the conductor. Kev sib txheeb ntawm Resistivity thiab Resistance yog: R=ρlA, qhov twg ρ yog qhov resistivity, l yog qhov ntev ntawm tus neeg xyuas pib thiab A yog qhov chaw hla ntu.

Koj puas tuaj yeem foob rau kev tawm tsam kev tawm tsam?
Txoj xov zoo rau cov neeg xauj tsev feem ntau yog kev tawm tsam tus tswv tsev yog txhaum cai hauv ntau lub xeev-cov tswv tsev uas koom nrog nws tuaj yeem nres thiab / lossis foob, qee zaum kom tau nyiaj ntau. Yuav ua li cas txiav txim siab tawm tsam kev tawm tsam?
Nyob rau hauv qhov kev txiav txim siab yog qhov kev sib tw yog kev tawm tsam kev tawm tsam?
Lub Ntiaj Teb Beat paub txog nws tsis lees paub cov khoom siv thiab cov qauv niaj hnub, kev sim tshuaj, thiab kev ywj pheej ntawm sab ntsuj plig thiab kev sib deev. Nws hloov zuj zus nyob rau xyoo 1960 los ua ib feem ntawm hippie thiab loj dua counterculture txav.
Qhov kev tawm tsam tawm tsam nyob qhov twg?

Qhov twg yog qhov kev txiav txim siab rau kev tsis lees paub thiab rau kev ua kom muaj kev tawm tsam ntawm kev tawm tsam?
Kev qhuab ntuas tau siv los ntawm cov thawj coj loj hauv cov tub rog Romanrau txim rau cov koom haum lossis pab pawg loj ua txhaum cai, xws li kev ua phem, kev tawm tsam, kev tawm tsam, thiab kev tsis ncaj ncees, thiab rau lub pacification ntawm rebellious legions.
Thaum twg yog qhov kev tawm tsam kev tawm tsam pib?
Nws yog los ntawm qhov kev txav no uas cov poj niam nyob deb nroog hauv lub xeev Andhra Pradesh tsim keeb kwm. Lub zog loj hlob tawm ntawm kev paub los ntawm lub hom phiaj kev paub nyeem ntawv lub National Literacy Mission (NLC) tau pib ua haujlwm hauv Nellore District hauv Lub Ib Hlis 1990.
