Cov spectrum no suav nrog ntau yam nthwv dej, los ntawm cov nthwv dej xov tooj cua ntev heev mus rau cov nthwv dej gamma ntev heev… Nyeem ntxiv

Lub zog hauv Alternating Current Circuits Alternating current circuits (AC) yog ib qho tseem ceeb ntawm cov tshuab hluav taws xob niaj hnub no. Ib qho ntawm cov ntsiab lus tseem ceeb uas yuav tsum nkag siab hauv AC circuits yog lub zog. Lub zog hauv AC circuit tsis yog tsuas yog lub zog tiag tiag tab sis kuj muaj lub zog reactive thiab lub zog pom tseeb. Tsab xov xwm no yuav piav qhia kom meej ... Nyeem ntxiv

Cov Hluav Taws Xob Hloov Pauv Kev Taw Qhia Cov hluav taws xob hloov pauv (AC) ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv hluav taws xob thiab hluav taws xob. Hauv cov hluav taws xob AC, cov hluav taws xob hloov pauv kev taw qhia tsis tu ncua, tsis zoo li cov hluav taws xob ncaj qha (DC), uas ntws mus rau hauv ib qho kev taw qhia. Tsab xov xwm no yuav piav qhia txog cov hauv paus ntawm AC circuits, lawv cov khoom tseem ceeb, thiab qee qhov piv txwv thiab kev siv ntawm cov circuits no… Nyeem ntxiv

Kev Hloov Pauv Tam Sim No (AC) thiab Voltage Kev Taw Qhia Kev hloov pauv tam sim no (AC) thiab voltage yog cov ntsiab lus tseem ceeb hauv kev lag luam hluav taws xob thiab khoom siv hluav taws xob. AC yog ib hom hluav taws xob uas cov dej ntws hloov pauv kev taw qhia tsis tu ncua, sib piv rau tam sim no ncaj qha (DC), uas ntws tas li hauv ib qho kev taw qhia. Alternating voltage kuj hloov pauv tus nqi thiab kev taw qhia raws li kev hloov pauv tam sim no. Tsab xov xwm ... Nyeem ntxiv

Cov Ntawv Thov ntawm Electromagnetic Induction hauv Technology Niaj Hnub Electromagnetic induction yog ib qho xwm txheej lub cev uas Michael Faraday tau tshawb pom hauv xyoo 1831, qhov twg lub zog hloov pauv magnetic tsim lub zog electromotive (EMF) hauv tus neeg coj. Lub hauv paus ntsiab lus no txhawb nqa ntau yam kev tsim kho tshiab uas peb siv txhua hnub, los ntawm cov tshuab hluav taws xob mus rau cov khoom siv hluav taws xob. Tsab xov xwm no yuav tshawb nrhiav ntau yam… Nyeem ntxiv

Kev Ua Tus Kheej: Cov Ntsiab Cai, Kev Xam, thiab Kev Siv Hauv Kev Siv Tshuab Niaj Hnub Kev ua tus kheej yog lub tswv yim tseem ceeb hauv electromagnetism uas ntsuas lub peev xwm ntawm lub kauj los ua kom muaj lub zog electromotive (EMF) hauv nws tus kheej los teb rau kev hloov pauv ntawm tam sim no hla nws. Lub hauv paus ntsiab lus no yog qhov tseem ceeb hauv kev tsim cov khoom siv hluav taws xob ntau yam xws li inductors, transformers, thiab systems… Nyeem ntxiv

Txoj Cai Lenz: Cov Ntsiab Cai Tseem Ceeb thiab Cov Ntawv Siv Hauv Electromagnetism Txoj Cai Lenz yog ib qho ntawm cov ntsiab cai tseem ceeb hauv electromagnetism uas piav qhia txog yuav ua li cas hluav taws xob tam sim no uas raug tsim los ntawm lub zog hloov pauv magnetic yuav muaj kev taw qhia uas tawm tsam lub zog hloov pauv. Tshawb pom los ntawm German physicist Heinrich Lenz hauv xyoo 1834, txoj cai no ua lub luag haujlwm tseem ceeb hauv kev nkag siab txog qhov xwm txheej ntawm electromagnetic induction… Nyeem ntxiv

Txoj Cai Faraday Kev Taw Qhia Txoj cai ntawm kev siv hluav taws xob los ntawm ...

Lub Zog Uas Tau Txais Kev Pab (EMF) Kev Taw Qhia Lub Zog Uas Tau Txais Kev Pab (Lub Zog Hluav Taws Xob), lossis feem ntau hu ua Induced EMF, yog ib qho xwm txheej uas lub zog sib nqus hloov pauv tsim cov hluav taws xob hauv tus neeg coj hluav taws xob. Lub hauv paus ntsiab lus no yog lub hauv paus ntawm ntau yam thev naus laus zis niaj hnub no, suav nrog cov tshuab hluav taws xob thiab cov transformers. Qhov xwm txheej no tau piav qhia thawj zaug los ntawm Michael Faraday hauv xyoo 1831 thiab tom qab ntawd tau dhau los ua… Nyeem ntxiv
