Taw qhia:

Peb paub tias qhov sib npaug sib npaug tsis sib xws, (RT) tuaj yeem pom thaum ob lossis ntau tus tiv thaiv tau txuas nrog ua ke hauv ob qho tib si yog tias tib tus nqi tam sim no ntws los ntawm txhua qhov khoom siv., Ua ke yog tias lawv muaj tib qhov hluav taws xob siv hla lawv. los yog kev sib txuas ntawm ob qho tib si, thiab cov kev sib txuas no ua raws Ohm Txoj Cai. Txawm li cas los xij, qee zaum hauv cov kab hluav taws xob nyuaj xws li choj lossis T tes hauj lwm, peb tsis tuaj yeem siv Ohm Txoj Cai ib leeg kom pom qhov hluav taws xob lossis cov dej ntws ntws hauv lub voj voog raws li hauv daim duab (1).

Rau cov hom kev suav no, peb xav tau qee txoj cai uas tso cai rau peb kom tau txais qhov sib npaug ntawm Circuit thiab rau qhov no peb tuaj yeem siv Kirchhoff Txoj Cai Circuit. [1]

Kauj Ruam 1: Cov Lus Txhais Hauv Circuit Analysis:

Cov Lus Txhais Hauv Circuit Analysis

Ua ntej peb mus rau hauv Kirchhoff txoj cai. peb thawj zaug yuav piav qhia yam tseem ceeb hauv kev tshuaj xyuas Circuit uas yuav siv rau hauv kev thov Kirchhoff txoj cai.

1-Circuit-Circuit yog ib txoj kab kaw uas ua rau muaj hluav taws xob ntws mus.

2-Txoj Kev-ib kab ntawm kev txuas cov ntsiab lus lossis cov khoom siv.

3-Node-lub node yog kev sib txuas, kev sib txuas, lossis lub davhlau ya nyob twg hauv ib qho kev sib txuas uas muaj ob lossis ntau lub ntsiab lus sib txuas lossis sib koom ua ke muab cov ntsiab lus sib txuas ntawm ob lossis ntau ceg. Lub node yog qhia los ntawm tus dot.

4-Ceg-ib ceg yog ib leeg lossis pab pawg ntawm cov khoom xws li cov neeg tawm tsam lossis cov khoom siv uas txuas nrog ntawm ob lub node.

5-Loop-lub voj yog txoj hauv kev kaw yooj yim hauv ib qho kev sib txuas uas tsis muaj cov khoom sib txuas lossis cov node tau ntsib ntau dua ib zaug.

6-Mesh-lub mesh yog ib txoj kab uas kaw ib txoj kab uas tsis muaj lwm txoj hauv kev. Tsis muaj cov loops sab hauv lub mesh.

Kauj Ruam 2: Kirchhoff Ob Txoj Cai:

Kirchhoff Ob Txoj Cai
Kirchhoff Ob Txoj Cai

Xyoo 1845, tus kws kho mob German, Gustav Kirchhoff tau tsim ib khub lossis teeb tsa cov cai lossis cov cai uas cuam tshuam nrog kev txuag hluav taws xob tam sim no thiab lub zog hauv cov hluav taws xob. Ob txoj cai no feem ntau hu ua Kirchhoff's Circuit Laws nrog ib ntawm Kirchhoff cov kev cai lij choj cuam tshuam nrog cov dej ntws tam sim no nyob ib puag ncig ib puag ncig kaw, Kirchhoff's Voltage Law, (KCL) thaum lwm txoj cai lij choj cuam tshuam nrog cov khoom siv hluav taws xob tam sim no hauv ib qho kev kaw, Kirchhoff's Voltage Law, (KWV).

Peb yuav siv qhov kev sib tw no los thov KCL thiab KVL raws li hauv qab no:

1-Faib Circuit Court rau ntau lub loops.

2-Teeb tsa kev taw qhia ntawm kev siv KCL. Teeb 2 qhov kev qhia tam sim no raws li koj xav tau, tom qab ntawd siv lawv kom tau txais cov lus qhia ntawm tus thib peb raws li hauv qab hauv daim duab (4).

Siv Kirchhoff Txoj Cai Tam Sim No, KCLAt ntawm A: I1 + I2 = I3

Ntawm tus lej B: I3 = I1 + I2 Siv Kirchhoff's Voltage Law, KVL

qhov sib npaug tau muab raws li: Loop 1 tau muab raws li: 10 = R1 (I1) + R3 (I3) = 10 (I1) + 40 (I3)

Loop 2 muab raws li: 20 = R2 (I2) + R3 (I3) = 20 (I2) + 40 (I3)

Loop 3 muab raws li: 10 - 20 = 10 (I1) - 20 (I2)

Raws li I3 yog qhov sib npaug ntawm I1 + I2 peb tuaj yeem sau qhov sib npaug li; Eq. Tsis muaj 1: 10 = 10I1 + 40 (I1 + I2) = 50I1 + 40I2 Eq. Tsis muaj 2: 20 = 20I2 + 40 (I1 + I2) = 40I1 + 60I2

Tam sim no peb muaj ob qho "Sib Txawv Sib Txawv" uas tuaj yeem txo qis kom muab qhov tseem ceeb ntawm I1 thiab I2 Kev hloov pauv ntawm I1 raws li I2 muab rau peb

tus nqi ntawm I1 li -0.143 Amps Kev hloov pauv ntawm I2 raws li I1 muab rau peb tus nqi ntawm I2 li +0.429 Amps

Raws li: I3 = I1 + I2 Qhov tam sim no ntws hauv resistor R3 muab raws li: I3 = -0.143 + 0.429 = 0.286 Amps

thiab qhov hluav taws xob hla tus tiv thaiv R3 tau muab raws li: 0.286 x 40 = 11.44 volts

Cov cim tsis zoo rau I1 txhais tau tias cov lus qhia ntawm cov dej ntws tam sim no thaum pib xaiv tsis raug, tab sis tseem tseem siv tau. Qhov tseeb, lub roj teeb 20v tab tom them lub roj teeb 10v. [2]

Nco tseg:

Kirchhoff txoj cai tuaj yeem siv rau ob qho AC thiab DC cov hluav taws xob qhov twg hauv AC qhov kev tiv thaiv yuav suav nrog lub tshuab hluav taws xob thiab cov kauj tsis yog tsuas yog tiv thaiv ohmic.
