Muaj tseeb peb txhua tus tau nug cov lus nug: yuav ua li cas noog tswj kom nyob nyab xeeb thiab suab thaum nyob ntawm cov xov? Tom qab tag nrho, cov khoom siv hluav taws xob nqa tau ntau pua volts thiab tuaj yeem tsim kev puas tsuaj rau tib neeg. Vim li cas cov tib neeg yuav tsum tsis txhob kov lub xaim uas xa tawm tam sim no, thiab cov noog thiaj li yooj yim kov cov xaim rau cov xuab moos? Cov lus teb tau yooj yim dua li nws yuav zoo li.
Txhua yam theem pib tau yooj yim
Cov lus zais ntawm kev noj qab haus huv zoo ntawm cov noog ntawm cov xov hlau yog cov lus qhia hauv cov txiaj ntsig zoo ntawm physics thiab hluav taws xob engineering.
Qhov hluav taws xob hluav taws xob tshwm sim thaum them cov pa hluav taws xob txav ntawm ob qho chaw. Muaj cov hlau nrog cov ntsuas hluav taws xob sib txawv ntawm qhov xaus, cov khoom ntim them tawm ntawm ib qho mus rau lwm qhov. Nyob rau tib lub sijhawm, tus noog nyob hauv huab cua rau ntau lub sijhawm, thiab nws, nyeg, yog dielectric (cov khoom siv uas tsis muaj peev xwm los tuav lub zog hluav taws xob).
Thaum cov noog tau tso rau ntawm cov xaim hluav taws xob, tsis muaj hluav taws xob tshwm sim. Qhov no yog vim hais tias tus noog yog ib puag ncig nkaus xwb los ntawm dielectric - huab cua. Ntawd yog, tsis muaj qhov tam sim no yog ua los ntawm cov hlau thiab noog. Txhawm rau kev txav ntawm cov lus hais kom ua tau, qhov chaw nrog qis qis yog qhov xav tau, uas tsis tuaj.
Yog li ntawd, tib lub voltage tsis ceeb cov noog. Tab sis, nyob rau hauv qhov xwm txheej uas muaj tis plaub tis kov ib qho xov txuas, qhov voltage ntawm uas yog qhov sib txawv, nws tam sim ntawd yuav raug ntaus los ntawm lub zog tam sim no (uas yuav luag tsis yooj yim, vim tias cov xov hlau muaj nyob ntawm qhov kev ncua deb hauv kev sib raug zoo rau ib leeg).
Noog thiab xov hlau
Muaj qee kis uas cov noog tau ua rau lub laj kab hluav taws xob tsis zoo. Muaj qee qhov xwm txheej zoo li no, tab sis lawv muaj nyob: noog nqa ib qho khoom hauv lawv nqaj uas tuaj yeem ua hluav taws xob los ua rau luv luv ntawm txoj kab. Qhov no yog vim qhov tseeb tias cov khoom siv (piv txwv li xaim) yog hom ntawm tus choj, tus neeg xyuas pib thiab, nyob rau hauv kev sib cuag nrog cov hlau, tam sim no ntws.
Yuav kom ib tug noog kom tau txais qhov tiag tiag hluav taws xob, koj yuav tsum cia pw ntawm insulators. Ntxiv mus, qhov loj me ntawm cov feathered yuav tsum muaj nqis. Ib tug noog loj tuaj yeem tsim kom muaj hluav taws xob tsim hluav taws xob, uas yuav muaj qhov cuam tshuam tsis zoo rau nws.
Cov neeg tseem tuaj yeem kov cov hluav taws xob, tab sis tsuas yog siv cov cuab yeej tshwj xeeb thiab thev naus laus zis.
