Dab tsi yog qhov txawv ntawm AC thiab DC?

Hluav taws xob lub hwj chim rau peb lub ntiaj teb niaj hnub, tab sis tsis yog txhua qhov hluav taws xob yog tib yam. Hloov lwm yam tam sim no (AC) thiab ncaj qha tam sim no (DC) yog ob qho xwm txheej hluav taws xob, thiab nkag siab txog lawv qhov kev tshawb fawb txog cov hluav taws xob lossis thev naus laus zis uas ntseeg tau rau nws. Kab lus no tsoo cia qhov sib txawv ntawm AC thiab DC, lawv cov ntawv thov, thiab lawv qhov tseem ceeb.

1. Kev txhais thiab ntws

Qhov tseem ceeb ntawm AC thiab DC lus dag hauv cov kev taw qhia ntawm qhov ntws tam sim no:

Direct tam sim no (DC): hauv DC, hluav taws xob them nqi rau ib qho, kev coj ua tas mus li. Xav hauv siab cov dej ntws ntws ntws los ntawm cov yeeb nkab yam tsis hloov nws chav kawm. DC yog hom hluav taws xob uas teeb meem tsim, ua rau nws zoo tagnrho rau cov khoom siv hluav taws xob me me zoo li cov xov tooj ntse, teeb meem, thiab laptops.

Hloov lwm yam tam sim no (AC): AC, ntawm qhov tod tes, ua ntu zus rov qab nws txoj kev coj. Es tsis txhob ntws ncaj, nws oscillates rov qab thiab tawm. Qhov no tam sim no yog dab tsi lub hwj nyiam tsev thiab cov lag luam vim tias nws tuaj yeem kis tau yooj yim dhau nrog tsawg tsawg kev poob haujlwm ploj.

2. Tiam thiab kis

DC tiam: DC hluav taws xob yog tsim los ntawm cov chaw zoo li roj teeb, cov khoom siv hnub ci, thiab DC cov tshuab luam. Cov chaw no muab cov hluav taws xob ntws khov kho kom khov kho, ua rau lawv haum rau cov ntawv thov uas xav tau lub zog ruaj khov thiab ntseeg tau.

Ac tiam: AC yog tsim los ntawm lwm cov hauv cov nroj tsuag fais fab. Nws yog tsim los ntawm kev tig cov hlau nplaum tsis pub dhau xaim ntawm xaim, tsim qhov tam sim no uas lwm txoj hauv kev. AC lub peev xwm yuav raug hloov mus rau siab dua lossis qis dua voltages ua rau nws muaj txiaj ntsig zoo rau kev kis tau deb dua

3. Voltage hloov pauv

Ib qho ntawm qhov tseem ceeb ntawm AC yog nws cov kev sib raug zoo nrog cov hloov pauv, uas tuaj yeem nce lossis txo cov hluav taws xob hluav taws xob ntxiv. High-voltage kis tau txo lub zog thaum lub zog thaum mus ncig ua si ntev, ua ac qhov kev xaiv uas nyiam tshaj plaws rau cov fais fab. DC, nyob rau hauv kev sib piv, yog qhov nyuaj dua los nqis los yog nqis ntaiv, tab sis niaj hnub thev naus laus zis xws li DC-DC Converters tau hloov kho nws cov peev txheej.

4. Kev thov

DC daim ntaub ntawv: DC feem ntau siv hauv cov khoom siv voltage tsawg thiab cov khoom siv hluav taws xob. Cov no suav cov khoos phis tawj, teeb coj kev zoo, hluav taws xob tsheb, thiab lub zog txuas ntxiv. Hnub ci ci ntsa iab, piv txwv li, tsim kho DC hluav taws xob, uas yuav tsum hloov dua siab tshiab rau AC lossis kev lag luam siv.

AC Daim ntawv thov: AC Powers peb lub tsev, chaw haujlwm, thiab kev lag luam. Cov cuab yeej siv hluav taws xob zoo li cov tub yees, cua txias, thiab TV rely rau AC vim tias nws tau txais hluav taws xob ntawm cov hluav taws xob hluav taws xob.

5. Kev Nyab Xeeb thiab Kev Ua Haujlwm

Kev Nyab Xeeb: AC qhov hluav taws xob siab tuaj yeem txaus ntshai, tshwj xeeb yog tias tsis tau ua kom zoo, thaum DC qhov qis dua voltage yog feem ntau muaj kev nyab xeeb rau kev siv me me. Txawm li cas los xij, ob qho tib si tuaj yeem xaiv txoj kev pheej hmoo yog tias tsis ntseeg Yexus.

Kev ua tau zoo: DC yog siv tau ntau dua rau kev hloov chaw deb-deb-deb ntawm kev hloov chaw thiab hluav taws xob hluav taws xob. AC zoo dua rau kev sib nrug deb rau kev sib kis mus ntev rau nws cov hluav taws xob qis ntawm cov hluav taws xob siab .Conclusion

Thaum AC thiab DC Ua lub hom phiaj sib txawv, lawv sib txuam hauv peb lub ntiaj teb. AC qhov ua tau zoo hauv kev sib kis thiab siv thoob plaws hauv tsev kho teeb meem ua rau nws tsis tseem ceeb, thaum DC qhov kev ruaj khov thiab sib zog nrog cov thev naus laus zis ua kom nws txuas ntxiv. Los ntawm kev nkag siab txog lub zog tshwj xeeb ntawm txhua tus, peb tuaj yeem txaus siab rau seb lawv ua haujlwm ua ke kom peb lub neej zoo.
