Cov khoom ua los ntawm cov hluav taws xob insulators zoo li roj hmab zoo li muaj qhov ua haujlwm siab heev thiab tsis tshua muaj hluav taws xob, thaum cov khoom ua los ntawm cov khoom siv hluav taws xob zoo li cov hlau yuav muaj tsis tshua muaj siab thiab siab conductivity. … Txhua yam khoom tiv thaiv hluav taws xob tam sim no, tshwj tsis yog cov khoom siv hluav taws xob, uas muaj qhov tsis kam ntawm xoom.
Puas yog conductors siab tiv thaiv?
Hlau xws li tooj liab typify conductors, thaum feem ntau cov khoom tsis yog xim hlau tau hais tias yog cov insulators zoo, muaj tsis tshua muaj siab heev rau cov nqi ntawm lawv. "Conductor" txhais tau hais tias sab nraud electrons ntawm lub atoms yog xoob khi thiab txav mus los ntawm cov khoom.
Puas conductors muaj siab tsis kam lossis tsis kam?
Cov khoom siv: Cov khoom siv uas muaj kev tiv thaiv tsawg heev qhov twg electrons tuaj yeem txav tau yooj yim. Piv txwv li: nyiaj, tooj liab, kub thiab txhuas. Insulators: Cov ntaub ntawv uas muaj kev tiv thaiv siab thiab txwv tsis pub khiav ntawm electrons.
Yuav ua li cas tiv thaiv tus neeg xyuas pib?
Resistance txhais tau tias kev tawm tsam rau qhov ntws ntawm hluav taws xob los ntawm tus neeg xyuas pib. Nws yog ib qho tseem ceeb uas yuav tau taw qhia tias conductivity thiab resistivity (cov cuab yeej uas txiav txim siab zaum kawg kuj) yog inversely proportional. Qhov ntau conductive ib yam yog, qhov tsawg kuj nws yuav muaj.
4 yam uas cuam tshuam txog kev tiv thaiv yog dab tsi?
Muaj 4 yam sib txawv uas cuam tshuamkev tiv thaiv:
- Cov khoom siv uas tus resistor yog ua.
- Qhov ntev ntawm qhov resistor.
- Lub thickness ntawm cov resistor.
- Qhov kub ntawm tus neeg xyuas pib.

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 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.
Tus neeg tsav tsheb puas tuag thaum kawg ntawm kev tsav tsheb?
Nyob hauv Tsav, Tus Tsav Tsheb tsis muaj txoj sia nyob zoo siab tom qab Muaj ib zaug, tus neeg tua neeg tawm tsam lawv hauv of the elevator thiab Tus Tsav Tsheb tsoo nws thaum Irene ntsia, txaus ntshai. Tom qab ntawd, muaj kev kub ntxhov thiab kev ua pauj ntau ntxiv.
