Hwj chim Factor . Hauv AC circuits , cov fais fab xwm txheej yog qhov piv ntawm qhov tiag zog uas yog siv los ua haujlwm thiab pom meej zog uas yog muab rau lub Circuit Court . Cov fais fab xwm txheej tuaj yeem tau txais txiaj ntsig hauv qhov ntau ntawm 0 txog 1. Thaum tag nrho cov zog yog reactive zog nrog tsis muaj tiag zog (feem ntau inductive load) - lub fais fab xwm txheej yog 0
Tib neeg kuj nug, txhais li cas los ntawm lub hwj chim factor?
Hauv hluav taws xob engineering, lub fais fab xwm txheej ntawm AC hluav taws xob zog system yog txhais raws li qhov piv ntawm qhov tiag zog absorbed los ntawm lub load mus rau pom tseeb zog ntws hauv Circuit Court, thiab yog ib tug dimensionless tooj nyob rau hauv lub sij hawm kaw ntawm −1 mus rau 1. Pom meej zog yog cov khoom ntawm RMS tam sim no thiab voltage.
Tsis tas li ntawd, lub cev muaj zog yog dab tsi? Fais fab xwm txheej yog ib qho kev ntsuas seb koj siv tau zoo npaum li cas hluav taws xob . Ib qho inductive load, zoo li a lub cev muaj zog , compressor lossis ballast, kuj xav tau Reactive Hwj chim tsim thiab txhawb nqa ib qho chaw sib nqus kom ua haujlwm.
Tsis tas li lo lus nug yog, koj ua li cas suav lub zog?
xam qhov pom tseeb zog , los yog Voltage Squared muab faib los ntawm Impedance, raws li muaj tseeb Hwj chim , los ntawm kev sib npaug tam sim no squared los ntawm qhov tsis kam hauv koj lub voj voog. Cov Hwj chim Factor yog Watts muab faib los ntawm Volt-Amps.
Lub hwj chim factor cuam tshuam li cas tam sim no?
Ib qho qis fais fab xwm txheej ua rau siab dua tam sim no ntws rau ib tug muab load. Raws li kab tam sim no nce, qhov voltage poob nyob rau hauv tus neeg xyuas pib nce, uas yuav ua rau ib tug qis voltage ntawm cov khoom. Nrog kev txhim kho fais fab xwm txheej , qhov voltage poob hauv tus neeg xyuas pib yog txo, txhim kho qhov voltage ntawm cov khoom siv.

Lub zog ntawm RC Circuit Court yog dab tsi?
Nyob rau hauv ib tug series RC Circuit Court txuas nrog AC voltage qhov chaw, voltage thiab tam sim no muaj ib theem sib txawv ntawm ϕ, qhov twg cosϕ = R √ R2 + (1 ω C) 2 cos ϕ = RR 2 + (1 ω C) 2. cosϕ yog hu ua power factor
Dab tsi yog tsib lub hauv paus Circuit Court Cheebtsam lawv lub tsev yog dab tsi?
Cov no yog cov feem ntau siv: resistors. Capacitors. LEDs. Transistors. Inductors. Integrated Circuits
Dab tsi yog tsib feem ntawm lub hauv paus hluav taws xob Circuit Court?
Qhov tseem ceeb ntawm cov hluav taws xob hluav taws xob yog tsim los ntawm cov khoom siv hluav taws xob, kev thauj khoom, xaim thiab hloov. Muaj ntau hom kev siv hluav taws xob. Feem ntau peb pom yog drybattery, cia roj teeb thiab lub tshuab hluav taws xob, thiab lwm yam
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog qhov txawv ntawm lub zog siv zog thiab lub zog thauj khoom?
Raws li nrog cov dav hlau inclined, cov khoom yuav tsum tau txav mus los yog lub zog muaj zog los yog thauj khoom thiab kev siv zog yog lub zog muab tso rau hauv kev txav mus los ntawm lwm qhov kawg ntawm lub fulcrum
