Menene VAC a cikin injiniyan lantarki?
Abubuwa
Kuna so ku san abin da gajeriyar VAC ke nufi a cikin sharuddan lantarki? Ni ƙwararren ma'aikacin lantarki ne kuma zan rufe wannan dalla-dalla a cikin ɗan gajeren labarin da ke ƙasa.
Kuna iya ganin 110VAC ko 120VAC da aka lakafta akan yawancin na'urorin lantarki.
Gabaɗaya, VAC kalma ce kawai da ake amfani da ita a injiniyan lantarki don AC volts. Wataƙila kun saba da volts na DC; wutar lantarki ce ta DC. Hakazalika, VAC tana wakiltar wutar lantarki ta AC. Abinda kawai kuke buƙatar sani shine duka VDC da VAC suna wakiltar ƙarfin lantarki.
Ci gaba da karantawa don ƙarin bayani.
Duk abin da kuke buƙatar sani game da VAC
Yawancin jihohi a Arewacin Amurka suna amfani da 110 ko 120 VAC. Kuma kuna iya ganin waɗannan alamomin akan wasu na'urori na lantarki kamar kwamfutoci, na'urorin lantarki na yanzu, da na'urorin multimeter na dijital. Amma ka san ma'anarsa?
VAC shine kalmar da ake amfani da ita don komawa AC volts. Don haka babu wani abu kamar wutar AC. Wutar lantarki ce kawai ta AC.
Koyaya, don samun daidai, dole ne ku fahimci bambanci tsakanin VAC da VDC.
Menene VDC da VAC?
Na farko, dole ne ku san game da DC da AC don fahimtar waɗannan sharuɗɗan biyu.
Kai tsaye (DC)
Ƙarfin DC yana gudana daga mummunan zuwa ƙarshen tabbatacce. Wannan kwararar ba ta kai tsaye ba, kuma baturin mota ɗaya ne sanannen misali.
Alternating current (AC)
Ba kamar DC ba, wutar AC tana gudana daga ɓangarorin biyu. Misali, a cikin kowane sakan da aka ba, ikon AC yana canzawa daga korau zuwa tabbatacce kuma daga tabbatacce zuwa korau. Babban wutar lantarki da ke shigowa gidanku shine mafi kyawun misalin wutar AC.
V DC da AC
Idan kun fahimci ikon AC da DC a sarari, ba ku da wani abin da za ku fahimta game da VDC da VAC.
Ga bayani mai sauƙi.
VDC tana wakiltar ƙimar wutar lantarki ta DC kuma VAC tana wakiltar ƙimar wutar AC. Idan ka ɗauki multimeter na dijital kuma ka bincika shi a hankali, za ka iya ganin waɗannan alamomin biyu. Koyaya, idan kuna son amfani da waɗannan saitunan akan na'urar multimeter, dole ne ku san waɗanne da'irori ne ke aiki tare da wutar lantarki na DC da kuma waɗanne da'irori masu ƙarfin AC.
A ina zan sami VAC?
Yawancin yankuna na Arewacin Amurka suna amfani da 110 ko 120 VAC don gidaje na yau da kullun. Kuna iya samun wannan alamar akan na'urorin AC. Koyaya, idan yazo Turai suna amfani da 220VAC ko 240VAC.
Quick Tukwici: Wutar wutar lantarki ta 120V AC ta bambanta daga 170V zuwa sifili. Sa'an nan kuma ya sake tashi zuwa 170V. Misali, alternating current ana maimaita sau 60 a cikin dakika daya. Wannan shine dalilin da ya sa yawancin tushen AC shine 60Hz.
RMS ƙarfin lantarki 120V AC
A gaskiya, 120V AC yana musanya zuwa 170V kuma ya ragu zuwa sifili. Wannan igiyar igiyar ruwa tana daidai da 120 volts DC kuma ana kiranta da RMS.
Yadda za a lissafta ƙimar RMS?
Anan shine dabarar kirga RMS.
VRMS V = kuKYAUTA*1/√2
Mafi girman ƙarfin lantarki 170V.
Saboda haka,
VRMS = 170*1/√2
VRMS = 120.21 V
Me yasa muke amfani da VAC?
Za ku rasa makamashi a duk lokacin da kuka yi ƙoƙarin canza makamashi daga wannan nau'i zuwa wani. Don haka, don rage wannan asarar makamashi, janareta suna samar da wutar lantarki a babban ƙarfin lantarki kuma suna watsa ta ta hanyar canza yanayin wutar lantarki.
Koyaya, gidaje na yau da kullun basa buƙatar wutar lantarki mai ƙarfi. Saboda haka, wutar lantarki AC ta ratsa ta hanyar wutan lantarki mai saukarwa kuma yana samar da ƙarancin wutar lantarki don amfanin gida.
muhimmanci: Yawancin na'urorin lantarki ba sa aiki akan wutar AC. Maimakon haka, suna amfani da ƙananan wutar lantarki na DC. Don haka, ƙarancin wutar lantarki AC yana jujjuya zuwa ƙaramin ƙarfin wutan DC ta hanyar gyara gada.
Dubi wasu labaran mu a kasa.
- Saita multimeter don baturin mota
- Gwajin juzu'in wutar lantarki
- Yadda ake gwada batirin mota tare da multimeter
