Voltage poob : Parallel Circuit
Qhov no txhais tau tias cov hluav taws xob poob hla txhua qhov tsuas yog tag nrho hluav taws xob ntawm Circuit Court muab faib los ntawm tus naj npawb ntawm cov resistors hauv lub Circuit Court , los yog 24 V / 3 = 8 V.
Yog li ntawd, koj yuav ua li cas xam qhov muaj peev xwm poob hauv ib lub voj voog?
Tag nrho cov tsis kam ntawm a series ntawm Circuit Court yog sib npaug rau qhov sib npaug ntawm cov neeg tawm tsam. Qhov hluav taws xob siv rau a series ntawm Circuit Court yog sib npaug rau cov lej ntawm tus kheej voltage poob . Cov hluav taws xob poob hla tus resistor hauv a series ntawm Circuit Court yog ncaj qha proportional rau qhov loj ntawm tus resistor.
Tsis tas li ntawd, ntsuas tam sim no li cas? Tam sim no tuaj yeem yog ntsuas siv lub ammeter. Hluav taws xob tam sim no tuaj yeem ncaj qha ntsuas nrog galvanometer, tab sis txoj kev no cuam tshuam nrog kev rhuav tshem cov hluav taws xob hluav taws xob, uas qee zaum tsis yooj yim. Tam sim no tuaj yeem yog ntsuas tsis tawg lub Circuit Court los ntawm kev ntes cov magnetic teb txuam nrog rau tam sim no.
Tsis tas li ntawd, koj yuav ua li cas thiaj nrhiav tau qhov sib txawv hauv ib lub voj voog?
Cov Muaj peev xwm sib txawv yog qhov poob hauv qhov hluav taws xob uas tshwm sim thoob plaws ib qho resistor li tam sim no ntws los ntawm nws. Hauv ib Circuit Court , Muaj peev xwm sib txawv los yog Voltage (V) = Tam sim no (I) * Resistance (R), los yog sau luv V = I * R. Hauv qhov no, kuv = 5 amps thiab R = 10 ohms, yog li V = I * R = 5 amps * 10 ohms = 50 volts.
Dab tsi yog meant los ntawm tej zaum poob?
Voltage poob yog txhais raws li tus nqi ntawm hluav taws xob poob uas tshwm sim los ntawm tag nrho los yog ib feem ntawm ib tug Circuit Court vim impedance. Ib qho piv txwv zoo siv los piav qhia hluav taws xob , tam sim no thiab hluav taws xob poob yog vaj hose. Cov xwm txheej no ua rau lub nra hnyav ua haujlwm nrog tsawg dua hluav taws xob thawb qhov tam sim no.

Yuav ua li cas koj pom lub voj voog ntawm lub voj voog?
Lub voj voog = π x txoj kab uas hla ntawm lub voj voog (Pi multiplied los ntawm txoj kab uas hla ntawm lub voj voog). Cias faib lub voj voog los ntawm π thiab koj yuav muaj qhov ntev ntawm txoj kab uas hla. Txoj kab uas hla tsuas yog lub vojvoog zaug ob, yog li faib txoj kab uas hla los ntawm ob thiab koj yuav muaj lub vojvoog ntawm lub voj voog
Muaj pes tsawg lub voj voog yuav haum rau hauv ib lub voj voog?
Tus kws sau ntawv, Eckard Specht, kuj koom nrog hauv kev tshawb nrhiav kev daws teeb meem, thiab qhov tseeb, feem ntau cov kev daws teeb meem tau pom los ntawm nws, thiab muaj cov kev daws teeb meem txog li 2600 lub voj voog nyob rau hauv ib lub voj voog loj, nrog rau cov duab layouts. Rau txhua lub voj voog qhov piv ntawm r / R tau muab, thiab qhov no tuaj yeem siv los nrhiav cov lus teb
Dab tsi yog qhov txawv ntawm electrostatic muaj peev xwm thiab electrostatic muaj peev xwm zog?
Tsis muaj qhov sib txawv ntawm electrostatic potentialenergy thiab hluav taws xob (al) muaj peev xwm zog. Lub peev xwm hluav taws xob ntawm ib qho taw tes yog kev ua haujlwm los ntawm lwm qhov kev quab yuam hauv kev txav chav tsev zoo los ntawm ib qho arbitrarilychosen xoom ntawm lub peev xwm (feem ntau infinity) mus rau lub ntsiab lus
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
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
