Voltage ntawm ob theem hu ua Kab hluav taws xob . Kab hluav taws xob = 1.73* Phase voltage . Hluav taws xob voltage nruab nrab ib 'live' theem thiab 'neutral' hauv ib peb theem Distribution system yog 220 V.
Kuj nug, dab tsi yog qhov voltage ntawm ob theem hauv peb theem khoom?
3 faaj system qhia nrog kab voltages . Cov kab hluav taws xob yog 440 volt. Kuj cov voltage ntawm ib qho ib theem thiab nruab nrab rau ib 3 faaj Qhov system yog 240 volts.
Tsis tas li ntawd, qhov voltage ntawm 3 theem yog dab tsi? Qhov hluav taws xob thiab cov nqi tam sim no hauv Peb - Theem Systems Nrog rau saum Circuit Court, kab hluav taws xob yog kwv yees li 208 volts. Phase voltage hais txog cov hluav taws xob ntsuas hla ib qho khoom siv (qhov chaw winding lossis load impedance) hauv qhov sib npaug peb - theem qhov chaw los yog load. Rau lub Circuit Court uas tau teev saum toj no, lub theem voltage yog 120v.
Hauv qhov no, qhov voltage ntawm ob theem yog dab tsi?
Cov voltage nruab nrab tus ob ob txhais ceg (hu ua theem rau theem los yog kab rau kab) yog 240V thiab cov theem rau nruab nrab hluav taws xob yog 120v.
Dab tsi yog qhov zoo ntawm 3 theem system?
Cov qhov zoo ntawm peb theem tshaj ib leeg theem system yog: Tus nqi ntawm cov khoom siv conductor xav tau tsawg dua rau peb theem system . Lub zog hauv tsev thiab kev lag luam / kev lag luam tuaj yeem muab los ntawm tib qhov chaw rau peb theem system . Kev tswj hluav taws xob ntawm peb theem system zoo dua.

Dab tsi yog qhov txawv ntawm kab rau kab voltage thiab kab rau nruab nrab voltage?
Qhov voltage ntawm ob kab (piv txwv li 'L1' thiab 'L2') yog hu ua kab rau kab (los yog theem rau theem) voltage. Qhov voltage hla txhua qhov winding (piv txwv li ntawm 'L1' thiab 'N' yog hu ua kab rau nruab nrab (lossis theem voltage)
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 kev hloov pauv ntawm cov khoom uas txav ntawm qhov chaw mus rau qhov chaw ntawm - 12 m?
Kev piav qhia: Qhov kev txav ntawm ib qho khoom txav ntawm qhov chaw mus rau qhov chaw ntawm − 12 m yog 12 meters. Qhov kev ncua deb ntawm lub hauv paus chiv keeb mus rau qhov siab tshaj plaws txoj hauj lwm yog hu ua displacement ntawm ib yam khoom. Qhov siab tshaj plaws kev hloov pauv ntawm cov khoom nyob rau hauv ib nthwv dej yog hu ua crest thiab qhov tsawg kawg nkaus hloov pauv yog hu ua trough
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
