Ib 240 hluav taws xob yog qhov ntsuas ntawm kab mus rau kab thiab cov 120 volts yog ntsuas los ntawm ob kab mus rau nruab nrab lossis grounded conductor. Ib 480 hluav taws xob feem ntau yog rau cov motors thiab qee cov khoom siv thiab cov 277v ua yog siv rau teeb pom kev zoo. Yuav tsum muaj transformer hauv cov tshuab no kom tau txais 120 volts rau receptacles.
Tsis tas li ntawd, koj puas tuaj yeem tau txais 120v ntawm 277v?
Hauv qhov no, cov lus teb yog yog. Ib yam li cov fluorescent ballasts cim 120 v - 277v ib , LED tsav tsheb cim 120 v - 277v ua tus kheej-kho rau qhov voltage ntawm lub hwj huam mov yog muab, piv txwv li qhov voltage poob nyob rau hauv lub piav ntau yam. Piv txwv li, 120 v - 277v ua ua haujlwm ntawm txhua qhov hluav taws xob nruab nrab 120 v ib 240v.
Ib sab saum toj, puas yog 277 High Voltage? 277 Volts yog lub zog nkag ntawm kev xaiv rau feem ntau ntawm kev lag luam thiab kev lag luam. High voltage teeb pom kev zoo yog zoo dua los ntawm kev pom kev ua tau zoo. Feem ntau cov chaw lag luam tau txais lawv lub zog hauv 480 / 277 volt 3 theem 4 xaim system, vim 277 yog theem-rau-nruab nrab hluav taws xob rau 480's theem-rau-theem.
Ib yam li ib tug yuav nug, qhov txawv ntawm 277v thiab 120v yog dab tsi?
208V yog qhov voltage nruab nrab theem ntawm 3-theem "Y" Circuit Court uas yog 120 V los ntawm nruab nrab mus rau tej kub. 480V yog qhov voltage nruab nrab theem ntawm 3-theem "Y" Circuit Court uas yog 277v ua los ntawm kub mus rau nruab nrab. Ua raws li 110V piv rau 120 V strangeness, motors npaj los khiav ntawm 480V peb theem feem ntau sau npe ua 440V.
Yuav ua li cas kom tau txais 277 voltage?
Yog li ntawd, 277 volts yog tsim los ntawm tus qauv 480 VAC peb-theem mov transformer. 277 volts yog theem rau nruab nrab hluav taws xob ua 480 hluav taws xob 3-theem hluav taws xob system.

Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
