Electrical Conductor vs Insulator
Hluav taws xob rwb thaiv tsev thiab hluav taws xob conductance yog ob qho tseem ceeb tshaj plaws ntawm cov teeb meem. Hauv kev lag luam xws li hluav taws xob engineering, hluav taws xob engineering, electromagnetic teb txoj kev xav, thiab ib puag ncig physics, cov khoom rwb thaiv tsev thiab cov khoom siv hluav taws xob muaj qhov tseem ceeb. Txij li thaum peb cov kev lag luam khiav los ntawm hluav taws xob, nws yog ib qho tseem ceeb kom muaj kev nkag siab zoo txog cov teeb meem no. Qee qhov xwm txheej niaj hnub no tuaj yeem piav qhia siv cov kev coj ua thiab kev rwb thaiv tsev ntawm cov teeb meem. Nyob rau hauv tsab xov xwm no, peb yuav tham txog dab tsi hluav taws xob conductance thiab hluav taws xob rwb thaiv tsev yog dab tsi, dab tsi yog qhov kev xav tom qab hluav taws xob conduction thiab hluav taws xob rwb thaiv tsev, lawv qhov zoo sib xws, cov ntaub ntawv uas qhia txog cov khoom ntiag tug, cov xwm txheej niaj hnub cuam tshuam nrog kev coj ua thiab kev rwb thaiv tsev, thiab thaum kawg lawv qhov sib txawv..
YElectrical Conductors
Cov khoom siv hluav taws xob txhais tau tias yog cov khoom siv nrog tus nqi dawb uas tuaj yeem txav mus los. Nyob rau hauv cov ntsiab lus no, vim hais tias txhua yam khoom muaj tsawg kawg yog ib tug dawb electron vim thermal agitation txhua yam khoom yog ib tug conductor. Qhov no muaj tseeb hauv kev xav. Txawm li cas los xij, nyob rau hauv kev xyaum conductors yog cov ntaub ntawv uas yuav cia qee qhov tam sim no dhau los ntawm lawv. Cov hlau muaj cov qauv hlau sib txuas, uas yog ib qho zoo ion engulfed hauv hiav txwv ntawm electrons. Ib tug hlau pub tag nrho nws lub plhaub sab nrauv electrons rau lub pas dej electron. Yog li ntawd, hlau muaj ib tug ntau ntawm cov dawb electrons yog li ntawd lawv yog heev zoo conductors. Lwm txoj kev ntawm conduction yog lub qhov ntws. Thaum lub atom nyob rau hauv ib tug lattice qauv tso tawm ib tug electron, lub atom ua zoo. Lub plhaub tsis muaj hluav taws xob no hu ua lub qhov. Lub qhov no tuaj yeem nqa ib qho hluav taws xob los ntawm cov atom nyob sib ze ua rau lub qhov nyob hauv atom nyob sib ze. Thaum qhov kev hloov pauv no txuas ntxiv qhov no dhau los ua qhov tam sim no. Ions nyob rau hauv cov kev daws teeb meem ionic kuj ua raws li cov neeg nqa khoom tam sim no. Tag nrho peb cov kab hluav taws xob hluav taws xob yog tsim los ntawm kev ua hlau. Cov hlau thiab ntsev tov yog cov qauv zoo rau cov neeg siv khoom. Yog hais tias tus conductance ntawm ib tug conductor yog tsawg, nws txhais tau hais tias lub nruab nrab yog resisting tam sim no ntws. Qhov no yog hu ua qhov tsis kam ntawm tus neeg xyuas pib. Qhov tsis kam ntawm qhov nruab nrab ua rau lub zog poob hauv daim ntawv ntawm tshav kub.
Electrical Insulators
Hluav taws xob cov khoom siv hluav taws xob yog cov khoom siv uas tsis muaj nqi dawb. Tab sis nyob rau hauv kev xyaum, txhua yam khoom muaj ib co dawb electrons vim thermal agitation. Ib tug zoo meej insulator yuav tsis cia ib tug tam sim no dhau txawm hais tias qhov voltage sib txawv nyob rau hauv lub terminals yog infinite. Txawm li cas los xij, ib txwm insulator yuav cia tam sim no dhau tom qab ob peb puas volts. Thaum muaj hluav taws xob siab siv hla cov khoom siv insulating, cov atoms hauv cov khoom yuav polarize. Yog tias qhov voltage txaus, electrons yuav raug cais tawm ntawm atoms los tsim cov electrons dawb. Qhov no yog lub npe hu ua qhov tawg voltage rau cov khoom siv no. Tom qab qhov kev puas tsuaj, yuav muaj qhov ntws tam sim no vim qhov hluav taws xob siab. Cov dej distilled, mica thiab feem ntau ntawm cov yas yog cov piv txwv ntawm insulators.

Qhov txawv ntawm Cov Hluav Taws Xob thiab Cov Hluav Taws Xob yog dab tsi? • Hluav taws xob conductors muaj pes tsawg los yog tsawg heev, thaum hluav taws xob insulators muaj siab heev los yog infinite kuj. • Cov neeg ua haujlwm muaj tus nqi pub dawb, thaum cov insulators tsis muaj nqi dawb. • Cov neeg tsav tsheb tso tawm tam sim no, thaum cov insulators tsis ua. |
