Cov txiaj ntsig ntawm cov dej ntws los ntawm txhua txoj kev yog sib npaug rau tag nrho cov tam sim no uas ntws los ntawm qhov chaw. Koj tuaj yeem nrhiav tau tag nrho tsis kam hauv a Parallel Circuit Court nrog cov qauv hauv qab no: 1 / Rt = 1 / R1 + 1 / R2 + 1 / R3 + Yog tias ib qho ntawm thaum uas tig mus txoj kev tawg, tam sim no yuav ntws mus rau hauv tag nrho lwm txoj kev.
Nyob rau hauv no txoj kev, yuav ua li cas koj xam hwj chim nyob rau hauv ib tug parallel circuits?
Tag nrho zog yog sib npaug rau cov sum zog ntawm txhua yam. (Qhov no yog tib yam li nrog series circuits ). Tib qhov hluav taws xob muaj nyob thoob plaws txhua ceg ntawm a parallel Circuit Court thiab yog sib npaug rau qhov voltage. Tam sim no los ntawm a thaum uas tig mus ceg yog inversely proportionalto tus nqi ntawm cov kuj ntawm ceg.
Ib tug kuj yuav nug, ua li cas koj ntxiv resistors nyob rau hauv parallel? Qhov voltage ntawm txhua qhov resistor nyob rau hauv parallel yog ib yam. Tag nrho tsis kam ntawm ib set ntawm resistors inparallel pom los ntawm ntxiv up the reciprocals ntawm tsis kam qhov tseem ceeb, thiab tom qab ntawd muab qhov sib npaug ntawm qhov sib npaug: sib npaug tsis kam ntawm resistors inparallel : 1 / R = 1 / R1 + 1 / R2 + 1 / R3 +
Tom qab ntawd, ib tug kuj yuav nug, ua li cas koj xam tag nrho cov tsis kam?
Yog koj paub cov tag nrho tam sim no thiab voltageacross tag nrho Circuit Court, koj tuaj yeem nrhiav tau tag nrho kuj siv Ohm Txoj Cai: R = V / I. Piv txwv li, ib qho hluav taws xob sib txuas muaj qhov nruab nrab ntawm 9 volts thiab tag nrho zog 3amps. Cov kev tiv thaiv tag nrho RT = 9 volts / 3 amps = 3Ω.
Yuav ua li cas koj xam cov resistors nyob rau hauv parallel thiab series?
Rau xam tag nrho tag nrho tsis kam ntawm ib tug xov tooj ntawm resistors txuas nyob rau hauv txoj kev no koj ntxiv upthe tus neeg tiv thaiv. Qhov no yog ua tiav siv cov hauv qab no qauv : Rtotal = R1 + R2 + R3 thiab lwm yam. Piv txwv: To xam tag nrho tsis kam rau peb qhov no resistors hauv series.

Yuav ua li cas resistors coj nyob rau hauv series thiab nyob rau hauv parallel?
Txhua tus resistor nyob rau hauv ib tug series Circuit Court muaj tib tus nqi ntawm tam sim no ntws los ntawm nws. Txhua tus resistor nyob rau hauv ib qho hluav taws xob sib txuas muaj tib qhov hluav taws xob tag nrho ntawm qhov siv rau nws. Qhov tam sim no ntws los ntawm txhua tus resistor nyob rau hauv ib qho kev sib txuas sib txuas sib txawv, nyob ntawm qhov tsis kam
Yuav ua li cas koj xam cov kev hloov nyob rau hauv latitude?
Xam cov kev hloov ntawm Latitude thiab Longitude. Yog hais tias lub latitudes nyob rau hauv txawv hemispheres ces ntxiv. Yog tias cov latitudes nyob hauv tib hemispheres ces rho tawm. 60 ° 36' yog qhov hloov pauv inlatitude
Yuav ua li cas tshwm sim rau resistors nyob rau hauv parallel?
Resistors nyob rau hauv parallel - Thaum cov resistors txuas nrog nyob rau hauv parallel, cov khoom tam sim no sib npaug rau cov sum ntawm cov tam sim no los ntawm txhua tus resistor. Thaum cov resistors txuas nrog nyob rau hauv parallel, lawv muaj peev xwm sib txawv ntawm lawv
Yuav ua li cas koj xam cov kev hloov nyob rau hauv equilibrium?
Equilibrium yog txiav txim los ntawm kev ntxiv 'Initial' thiab 'Hloov ua ke. Yog tias x = 1.78 ces [C2H4]Eq yog qhov tsis zoo, uas yog tsis yooj yim sua, yog li, x yuav tsum sib npaug 0.098
Yuav ua li cas koj pom peb resistors nyob rau hauv parallel?
Voltage yog tib yam nyob rau hauv txhua feem ntawm lub parallel Circuit Court. Tus lej ntawm cov dej ntws los ntawm txhua txoj kev yog sib npaug rau tag nrho cov tam sim no uas ntws los ntawm qhov chaw. Koj tuaj yeem pom tag nrho cov kev tawm tsam hauv aParallel circuit nrog cov qauv hauv qab no: 1 / Rt = 1 / R1 + 1 / R2 + 1 / R3 +
