Circuit Court sib luag
Cov voj voog sib luag yog lub tswv yim tseem ceeb hauv kev siv hluav taws xob thiab kev tsim hluav taws xob. Txawm hais tias feem ntau tsis quav ntsej piv rau cov voj voog sib txuas, cov voj voog sib luag muaj cov yam ntxwv tseem ceeb thiab kev siv hauv ntau yam hluav taws xob thiab hluav taws xob. Hauv tsab xov xwm no, peb yuav tham txog kev txhais, cov yam ntxwv, kev xam, thiab kev siv ntawm cov voj voog sib luag hauv lub neej txhua hnub.
Kev Txhais Lus ntawm Parallel Circuit
Ib lub voj voog sib luag yog ib lub voj voog hluav taws xob uas cov khoom sib txuas ua ke. Qhov no txhais tau tias txhua lub khoom muaj ob lub qhov txuas ncaj qha rau lub zog hluav taws xob lossis qhov chaw tam sim no. Hauv lub voj voog sib luag, cov hluav taws xob raug faib ua ntau txoj kev, thiab txhua lub khoom tau txais tib lub zog hluav taws xob.
Daim duab qhia txog Circuit Court sib luag
Yuav kom nkag siab ntxiv, cia peb saib ib daim duab yooj yim ntawm lub voj voog sib luag:
“
(R1)
V ——( )—->
|
| (R2)
|—-( )—->
|
| (Rn)
|—-( )-—–>
“
Saum toj no yog ib daim duab ntawm ib lub voj voog sib luag nrog ntau lub resistors (R1, R2,…,Rn) txuas nrog sib luag. Ib lub voltage V raug siv rau txhua lub resistor ntawm tib qho chaw, yog li txhua lub resistor tau txais tib lub voltage V.
Cov yam ntxwv ntawm Parallel Circuits
Nov yog qee qhov yam ntxwv tseem ceeb ntawm cov voj voog sib luag:
1. Qhov Voltage tas li
Hauv ib lub voj voog sib txuas ua ke, txhua lub Cheebtsam (piv txwv li, lub resistor lossis capacitor) muaj tib lub zog hluav taws xob hla nws li lub zog hluav taws xob los ntawm qhov chaw. Lub zog hluav taws xob uas ib qho tivthaiv tau txais yog tib yam li lub zog hluav taws xob uas lwm cov tivthaiv tau txais.
2. Cais Tam Sim No
Cov hluav taws xob uas ntws los ntawm ib lub voj voog sib luag yog faib rau txhua txoj kev. Tag nrho cov hluav taws xob uas tawm hauv qhov chaw yog qhov sib npaug ntawm cov hluav taws xob uas ntws los ntawm txhua qhov khoom. Qhov no tuaj yeem qhia tau hauv kab zauv:
\[ Kuv_{total} = Kuv_{1} + Kuv_{2} + … + Kuv_{n} \]
qhov twg \(I_{total}\) yog tag nrho cov hluav taws xob los ntawm qhov chaw, thiab \(I_{1}, I_{2}, …, I_{n}\) yog cov hluav taws xob ntws los ntawm txhua feem.
3. Kev Tiv Thaiv Tag Nrho
Kev xam tag nrho cov kev tiv thaiv hauv lub voj voog sib luag yog qhov nyuaj me ntsis dua li hauv lub voj voog sib luag. Tag nrho cov kev tiv thaiv (R_total) hauv lub voj voog sib luag yog qhov rov qab ntawm qhov sib npaug ntawm cov kev rov qab ntawm txhua qhov kev tiv thaiv (R_n) hauv lub voj voog:
\[ \frac{1}{R_{total}} = \frac{1}{R_{1}} + \frac{1}{R_{2}} + … + \frac{1}{R_{n}} \]
Ua li no, tag nrho cov kev tiv thaiv hauv lub voj voog sib luag yeej ib txwm tsawg dua txhua qhov kev tiv thaiv hauv lub voj voog.
4. Qhov sib txawv ntawm qhov hluav taws xob
Hauv ib lub voj voog sib luag, qhov sib txawv ntawm qhov hluav taws xob thoob plaws txhua ceg ntawm lub voj voog yog tib yam. Qhov no yog ib qho ntawm cov txiaj ntsig tseem ceeb uas ua rau cov voj voog sib luag siv dav hauv kev siv hluav taws xob txhua hnub.
5. Kev Ua Tsis Tau Zoo ntawm Ib Qho ntawm Cov Cheebtsam
Yog tias ib qho khoom hauv lub voj voog sib luag tsis ua haujlwm lossis puas tsuaj (piv txwv li, tawg), lwm cov khoom yuav txuas ntxiv ua haujlwm. Qhov no yog vim tias lwm txoj kev tseem tuaj yeem nqa tam sim no yam tsis raug cuam tshuam los ntawm kev tawg hauv ib txoj kev.
Kev Xam Xam Circuit Sib Npaug
Yuav kom nkag siab zoo dua txog lub tswv yim no, cia peb saib ib qho piv txwv yooj yim. Xav tias peb muaj ib lub voj voog sib luag uas muaj peb lub resistors nrog cov nqi tsis kam hauv qab no:
– R1 = 10 Ω
– R2 = 20 Ω
– R3 = 30 Ω
Peb yuav pom tag nrho cov kev tiv thaiv (R_total) ntawm lub voj voog sib luag no.
Ua ntej, peb xam qhov rov qab ntawm txhua qhov kev tiv thaiv:
\[ \frac{1}{R_{1}} = \frac{1}{10} = 0.1 \]
\[ \frac{1}{R_{2}} = \frac{1}{20} = 0.05 \]
\[ \frac{1}{R_{3}} = \frac{1}{30} = 0.0333 \]
Tom qab ntawd, peb suav tag nrho cov nqi rov qab:
\[ \frac{1}{R_{total}} = 0.1 + 0.05 + 0.0333 = 0.1833 \]
Thaum kawg, peb xam tag nrho cov nqi tiv thaiv los ntawm kev noj qhov rov qab ntawm qhov sib npaug:
\[ R_{total} = \frac{1}{0.1833} \approx 5.46 \: Ω \]
Yog li, tag nrho cov tsis kam ntawm lub voj voog sib luag no yog li 5.46 Ω.
