AC thiab DC tam sim no

Raws li txoj kev loj hlob sai ntawm peb lub neej niaj hnub no, kev siv hluav taws xob yog qhov tseem ceeb ntawm kev tsav tsheb rau ntau yam kev txawj ntse hauv lub neej.

Nyob rau hauv peb lub qhov rooj tsis siv neeg accessories kev lag luam, kev siv hluav taws xob feem ntau muab faib ua ob hom: ib qho yog wired qauv. Feem ntau cov khoom poob rau hauv pawg no, xws li sensors, qee qhov keyboards, thiab lwm yam. Lub wired version yuav ruaj khov dua. Lwm qhov yog cov qauv wireless, uas siv cov roj teeb qhuav lossis cov pob khawm rau lub hwj huam mov thiab feem ntau yog siv nrog cov txais khoom siv tag nrho. Hauv kev sib piv, nws yog qhov yooj yim dua, thiab nws kuj yog qhov tsim nyog rau lub sijhawm tshwj xeeb uas tsis tuaj yeem xaim. Xws li peb cov M-505 wireless hloov series thiab M-271 wireless tuaj koom cov khoom siv ntiv tes thiab lwm yam. Peb cov khoom tsim nyog rau ob qho tib si DC thiab AC, thiab yog tsim los nrog cov tswv yim dav dav, yooj yim thiab universal.

Yog li, hluav taws xob yog ib qho tseem ceeb tsav tsheb. Kuv ntseeg tias peb tuaj yeem pom cov cim AC thiab DC tam sim no hauv peb lub neej. Yuav ua li cas peb paub qhov txawv ntawm ob thiab lawv cov kev siv?

Hluav taws xob yog ib hom hluav taws xob uas cuam tshuam nrog kev txav ntawm electrons raws tus neeg xyuas pib, xws li cov xaim. Kev khiav ntawm electrons tuaj yeem tshwm sim hauv ib qho kev taw qhia lossis ob qho tib si cov lus qhia raws cov hlau. Thaum hluav taws xob ntws mus rau hauv ib qho kev taw qhia, nws raug xa mus rau tam sim no ncaj qha (DC). Hloov tam sim no (AC) yog thaum cov electrons ntws nyob rau hauv ob qho tib si kev taw qhia - ib tug thiab ces rau lwm yam. Cov roj teeb tsim hluav taws xob ncaj qha, thiab cov hluav taws xob hluav taws xob hluav taws xob uas muab hluav taws xob rau cov tsev thiab lwm lub tsev siv hluav taws xob hloov pauv.

Voltage -- DC lub cev muaj zog.

Lwm qhov sib txawv ntawm AC thiab DC suav nrog cov nqi zog uas txhua tus tuaj yeem nqa tau. Txhua lub roj teeb yog tsim los tsim ib theem voltage xwb, thiab qhov voltage ntawm qhov tam sim no tsis tuaj yeem mus deb heev txog thaum nws pib poob zog. AC voltage los ntawm lub tshuab hluav taws xob hauv lub tshuab hluav taws xob tuaj yeem raug tsoo los ntawm lub zog los ntawm lwm lub tshuab, hu ua transformer.

Transformers siv nyob qhov twg qhov hluav taws xob voltage yuav tsum tau nce los yog txo. Piv txwv li, lawv feem ntau pom ntawm cov ncej hluav taws xob. Lub tshuab hluav taws xob tsim hluav taws xob tsim hluav taws xob ntawm qhov hluav taws xob siab heev kom nws tuaj yeem taug kev deb heev. Qhov voltage yuav tsum raug txo, txawm li cas los xij, ua ntej hluav taws xob mus txog hauv tsev thiab lwm lub tsev uas siv rau cov khoom siv hluav taws xob, tshuab thiab lwm yam khoom siv. AC kuj tuaj yeem hloov mus rau DC los ntawm lub adapter, xws li hom siv los siv lub zog ntawm lub roj teeb ntawm lub khoos phis tawj laptop.
