Thaum nws los txog rau hluav taws xob engineering thiab hluav taws xob, nws yog ib qho tseem ceeb kom nkag siab qhov sib txawv ntawm DC (direct tam sim no) thiab AC (alternating tam sim no) Cheebtsam. Ob hom hluav taws xob tam sim no ua lub luag haujlwm tseem ceeb hauv kev siv ntau yam khoom siv thiab tshuab, thiab kev nkag siab meej txog lawv qhov sib txawv yog qhov tseem ceeb rau txhua tus neeg ua haujlwm hauv cov haujlwm no.
DC tivthaiv yog tus cwj pwm los ntawm kev khiav ntawm tus nqi tas li hauv ib qho kev taw qhia. Hom tam sim no feem ntau siv hauv cov roj teeb, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob. DC Cheebtsam paub txog lawv qhov kev ruaj ntseg thiab muaj peev xwm muab lub zog ruaj khov thiab txhim khu kev qha. Lawv kuj tau siv dav hauv cov ntawv thov uas xav tau qhov hluav taws xob tsis tu ncua lossis tam sim no, xws li hluav taws xob circuits thiab cov tshuab tswj.
Lub AC tivthaiv, ntawm qhov tod tes, cuam tshuam nrog kev hloov pauv raws sijhawm nyob rau hauv cov kev taw qhia ntawm cov nqi ntws. Hom tam sim no feem ntau yog siv rau hauv tsev hluav taws xob hauv tsev, cov kab sib faib, thiab ntau hom hluav taws xob thiab cov tshuab hluav taws xob. AC Cheebtsam paub txog lawv lub peev xwm xa hluav taws xob mus ntev nrog kev poob qis thiab yog tus qauv rau feem ntau lub zog xa hluav taws xob thiab kev xa tawm.
Kev nkag siab txog qhov sib txawv ntawm DC thiab AC cov khoom yog qhov tseem ceeb rau kev tsim thiab kho cov tshuab hluav taws xob thiab hluav taws xob. Cov kws tshaj lij thiab cov kws tshaj lij yuav tsum muaj peev xwm paub qhov txawv ntawm ob hom hluav taws xob tam sim no thiab nkag siab tias lawv coj li cas hauv cov khoom sib txawv thiab cov khoom siv. Qhov kev paub no tseem ceeb heev rau kev ua haujlwm kom raug thiab kev nyab xeeb ntawm cov tshuab hluav taws xob thiab khoom siv.
Hauv cov ntsiab lus, qhov sib txawv ntawm DC thiab AC cov khoom yog qhov tseem ceeb rau kev lag luam hluav taws xob thiab hluav taws xob. Ob hom hluav taws xob tam sim no muaj cov yam ntxwv tshwj xeeb thiab kev siv, thiab kev nkag siab zoo ntawm lawv qhov sib txawv yog qhov tseem ceeb rau txhua tus neeg ua haujlwm nrog cov tshuab hluav taws xob thiab khoom siv. Los ntawm kev paub txog cov ntsiab lus ntawm DC thiab AC cov khoom, cov engineers thiab cov kws tshaj lij tuaj yeem tsim, txheeb xyuas, thiab daws teeb meem ntau yam ntawm cov tshuab hluav taws xob thiab hluav taws xob.
