Ua kom ntau rhiab heev , tag nrho cov kauj lossis hlau nplaum lossis tag nrho cov 'meter' yuav tsum tau hloov. Yog li txo tus ammeter qhov ntau yog xyaum tsis tau. nce qhov ntau ntawm ammeter , koj yuav tsum txuas lub shunt tsis kam nyob rau hauv parallel mus rau ceg uas koj xav ntsuas qhov tam sim no.
Ua raws li qhov no, koj yuav ua li cas nce qhov rhiab heev ntawm voltmeter?
Yog li cov rhiab heev ntawm voltmeter ntawm txav coil hom tuaj yeem ua tau nce yog los ntawm kev nce tus nqi ntawm G los yog txo tus nqi ntawm K. Tam sim no, rau ib co coil ntawm muab cross-sectional cheeb tsam i.e. A = Ld thiab muab magnetic flux ntom, tus nqi ntawm G yuav ua tau. nce los ntawm kev siv ntau tus lej ntawm cov hlau nyias nyias.
Ib yam li ntawd, vim li cas qhov ntau ntawm ammeter tuaj yeem nce ntxiv tab sis tsis tuaj yeem txo qis? Cov ntau ntawm ammeter tuaj yeem nce ntxiv tab sis tsis tuaj yeem txo qis . Yog vim li cas yog hais tias ib tug series resistor ua tsis tau hloov tam sim no uas yuav tsim tag nrho deflection. Yog I < I g I < I_ {g} I < Ig, ces tus nqi ntawm S yog qhov tsis zoo. Yog li, galvanometer ua tsis tau hloov ua ib qho ammeter ntawm ntau I <Ig I <I_{g} I<Ig.
Tsis tas li, koj ua li cas txiav txim siab qhov rhiab ntawm ammeter?
Qhov me me ntawm qhov tam sim no, qhov ntau "sensitive" qhov ammeter . Piv txwv li, ib ammeter nrog qhov siab tshaj tam sim no nyeem ntawm 1 milliampere yuav muaj a rhiab heev ntawm 1 milliampere, thiab yuav rhiab dua li ib ammeter nrog kev nyeem ntawv siab tshaj plaws ntawm 1 ampere thiab a rhiab heev ua 1 amper.
Meter rhiab heev yog dab tsi?
r sen·s?'tiv·?d·ē] (engineering) Qhov tseeb uas a meter tuaj yeem ntsuas qhov voltage, tam sim no, tsis kam, lossis lwm qhov ntau.

Qhov me me ntawm qhov tam sim no, qhov ntau 'sensitive' lub ammeter. Piv txwv li, ammeter nrog qhov siab tshaj plaws tam sim no nyeem ntawm 1 milliampere yuav muaj qhov rhiab heev ntawm 1 milliampere, thiab rhiab ntau dua li ammeter nrog qhov siab tshaj plaws nyeem ntawm 1 ampere thiab rhiab heev ntawm 1 ampere
Vim li cas rhiab heev yog qhov tseem ceeb rau cov khoom muaj sia?
Cov khoom muaj sia nyob muaj kev nkag siab rau lawv ib puag ncig. Kev nkag siab zoo yog qhov tseem ceeb vim tias nws tso cai rau cov khoom muaj sia mus ntes thiab teb rau cov xwm txheej hauv ntiaj teb nyob ib puag ncig lawv
Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
Cov txheej txheem ntawm lub ntiaj teb huab cua muaj qhov cua nyias heev tab sis kuj tuaj yeem kub heev?
Thermosphere - Lub thermosphere tom ntej no thiab huab cua nyias nyias ntawm no. Cov cua kub tuaj yeem kub heev hauv cov thermosphere. Mesosphere - Lub mesosphere npog tom ntej no 50 mais dhau ntawm stratosphere. Qhov no yog qhov uas feem ntau meteors hlawv thaum nkag
Yuav ua li cas kom tau kuv lub snowball Bush kom tawg?
Rau qhov zoo tshaj plaws flowering, muab snowball nrog tsawg kawg yog rau teev ncaj qha, puv hnub txhua hnub. Ntau qhov ntxoov ntxoo txhais tau tias tsawg lossis tsis muaj paj. Yog tias koj tsob ntoo snowball cog rau hauv qhov chaw ntxoov ntxoo, qhov no yuav yog vim li cas nws yuav tsis paj. Xav txog kev kho qhov chaw nyob ib puag ncig kom cia nyob rau hauv lub hnub ntau dua, lossis txav cov nroj tsuag mus rau qhov chaw tshav ntuj
