Muaj pes tsawg AC tuaj yeem khiav ntawm ib-theem 'meter'
Lub zog ib theem yog hais txog cov khoom siv hluav taws xob uas qhov hluav taws xob oscillates nyob rau hauv ib lub waveform. Qhov no yog qhov sib txawv ntawm peb theem zog, uas muaj peb lub zog sib cais, thiab siv rau hauv kev lag luam loj. Hauv ib theem zog, tam sim no ntws los ntawm ib lub xaim, thiab feem ntau yog siv rau hauv vaj tse thiab chaw lag luam me. Muaj ob yam tseem ceeb ntawm ib theem hluav taws xob: Hloov tam sim no (AC) thiab Direct tam sim no (DC).
Hloov tam sim no (AC) yog hom hluav taws xob ntau tshaj plaws siv hauv tsev thiab kev lag luam. AC yog tsim los ntawm cov tshuab hluav taws xob, uas hloov tshuab hluav taws xob rau hauv hluav taws xob hluav taws xob. Lub alternating tam sim no ntws rov qab thiab tawm mus, thiab hloov cov kev taw qhia ib ntus. Qhov no ua rau AC muaj txiaj ntsig zoo rau kev xa hluav taws xob mus ntev, uas yog vim li cas nws yog cov qauv hluav taws xob hauv ntau lub ntiaj teb.
Direct tam sim no (DC) yog hom thib ob ntawm ib theem zog mov. Tsis zoo li AC, ncaj qha tam sim no ntws hauv ib qho kev taw qhia. Hom hluav taws xob no feem ntau siv hauv cov khoom siv hluav taws xob me me xws li roj teeb thiab xov tooj ntawm tes. DC tuaj yeem ua haujlwm tau zoo dua AC rau qee lub hom phiaj, tab sis nws tsis yog feem ntau siv rau cov phiaj xwm hluav taws xob lossis hluav taws xob loj.
Tib theem zog tshuab muaj ntau yam nta thiab cov txiaj ntsig uas ua rau lawv muaj txiaj ntsig zoo rau cov chaw nyob thiab chaw lag luam me. Piv txwv li, ib theem zog yog feem ntau yooj yim rau nruab thiab tswj, thiab nws kuj tseem pheej yig. Tsis tas li ntawd, lub zog ib theem yog ib qho kev txhim khu kev qha ntawm lub zog, thiab nws tuaj yeem siv los ua lub zog ntau yam ntawm cov khoom siv thiab cov khoom siv.
Zuag qhia tag nrho, ib theem zog yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob uas muaj ntau yam kev siv. Txawm hais tias koj tab tom khiav lag luam me lossis tsuas yog xav tau lub zog koj lub tsev, lub zog ib theem tuaj yeem muab txoj hauv kev txhim khu kev qha thiab muaj txiaj ntsig rau koj kom tau raws li koj cov kev xav tau ntawm lub zog. Yog li, nws yog ib qho tseem ceeb kom nkag siab txog ntau hom thiab cov yam ntxwv ntawm lub zog ib theem txhawm rau txiav txim siab paub txog koj cov khoom siv hluav taws xob.
