Hypothesis: To induce ib tug tam sim no nyob rau hauv ib lub voj ntawm hlau , cov tej yam kev mob yuav tsum yog muaj magnetic teb. Qhov no yog vim hais tias thaum ib tug conductor txav los ntawm ib tug magnetic teb, ib induced tam sim no yog tsim.
Nyob rau hauv tas li ntawd, dab tsi yog tsim nyog los induce ib tug tam sim no nyob rau hauv ib tug conductor?
Cov tam sim no yog hais tias yog induced hauv tus thawj coj los ntawm magnetic teb. Ib kev xav tau rau qhov no electromagnetic induction coj qhov chaw yog qhov tus thawj coj , uas feem ntau yog ib daim ntawm hlau , yuav tsum yog perpendicular rau cov kab sib nqus ntawm lub zog thiaj li tsim tau lub zog siab tshaj plaws ntawm cov hluav taws xob dawb.
Tsis tas li ntawd, dab tsi induced tam sim no nyob ntawm? Cov induced tam sim no nyob ntawm ob qho tib si cheeb tsam ntawm lub kauj thiab kev hloov hauv magnetic teb. Nyob rau hauv ib lub coil ntawm cov xov hlau, txhua lub voj ua rau thaj tsam A mus rau sab xis ntawm qhov sib npaug, yog li qhov induced emf yuav yog proportional rau tus naj npawb ntawm loops nyob rau hauv ib lub kauj.
Ib tug kuj yuav nug, dab tsi yog peb txoj hauv kev uas qhov hluav taws xob tuaj yeem raug ntxias hauv lub voj voog ntawm cov hlau?
Yog li muaj peb txoj hauv kev uas emf tuaj yeem raug ntxias hauv lub voj:
- Hloov cov magnetic teb.
- Hloov thaj tsam ntawm lub voj.
- Hloov lub kaum sab xis ntawm daim teb thiab lub voj.
Dab tsi ua rau induced voltage?
Induced voltage yog ib qho hluav taws xob muaj peev xwm tsim los ntawm ib qho hluav taws xob teb, magnetic teb, los yog tam sim no. Qhov hluav taws xob generated nyob rau hauv theem nrab ntawm tam sim no transformer vim magnetic teb ntawm tam sim no txhaj nyob rau hauv nws thawj.

Yuav ua li cas cov protein nyob sab nraud ntawm tes ua rau muaj xwm txheej tshwm sim hauv lub cell?
Cov protein tuaj yeem dhau los ntawm daim nyias nyias thiab mus rau hauv lub cell, ua rau muaj teeb meem hauv lub cell. b. Ib qho protein nyob sab nraud ntawm tes tuaj yeem khi rau ib qho receptor protein ntawm lub xov tooj ntawm tes, ua rau nws hloov pauv thiab xa cov teeb liab hauv lub cell. Phosphorylation hloov cov duab ntawm cov protein, feem ntau ua rau nws
Yuav ua li cas cov thawj windings txuas thaum lub transformer yuav tsum tau ua nyob rau hauv ib tug 480 volt system?
Lub transformer muaj qhov polarity rho tawm thaum lub davhlau ya nyob twg H1 nyob ib sab ntawm lub davhlau ya nyob twg X1. Thaum lub 240/480 volt dual thawj tswj transformer yuav tsum tau ua los ntawm ib tug 240 volt system thawj winding yog kev cob cog rua nyob rau hauv parallel. Hauv Delta-connected transformer, theem thiab kab voltages sib npaug
Yuav ua li cas yog rau cov ntaub ntawv nug uas yuav tsum tau kawm nyob rau hauv ib tug ua txhaum cai?
Qee yam ntawm cov ntaub ntawv nug uas raug kuaj xyuas cov ntaub ntawv pov thawj tau hais hauv qab no. • Xav. • Tshawb xyuas. • Cov Nyiaj Txiag Nyiaj Txiag. • Daim ntawv cog lus. • Cov ntawv txais nyiaj. • Tub Sab Nraud. • Kev dag ntxias. • Kev cuav. • Kev tua tus kheej. • Kev tua neeg. • Nto nta. • Cov duab latent. • Kev hloov pauv. • Watermarks. • Ink stamps
Yuav ua li cas yog lub sum ntawm cov atomic masses ntawm tag nrho cov atoms nyob rau hauv ib tug qauv rau ib tug compound?
Cov mis loj ntawm ib yam khoom yog qhov sib npaug ntawm qhov nruab nrab atomic masses ntawm txhua lub atom sawv cev hauv cov tshuaj formula thiab qhia nyob rau hauv atomic mass units. Cov mis loj ntawm covalent compound tseem hu ua molecular mass
Yuav ua li cas oxygen tshwm sim hauv xwm piav qhia txog lub voj voog oxygen hauv qhov xwm txheej?
Piav lub voj voog oxygen hauv qhov xwm txheej. Oxygen muaj nyob rau hauv ob hom sib txawv hauv qhov xwm txheej. Cov ntaub ntawv no tshwm sim raws li cov pa roj carbon monoxide 21% thiab ua ke hauv daim ntawv oxides ntawm hlau thiab nonmetals, nyob rau hauv lub ntiaj teb crust, cua thiab dej. Oxygen rov qab mus rau qhov chaw los ntawm cov txheej txheem hu ua photosynthesis
