Chitsanzo cha lamulo lachiwiri la Kirchhoff

Zitsanzo 5 za Lamulo Lachiwiri la Kirchhoff

Komanso phunzirani nkhani zokhudza Kirchhoff’s Law ndi kukambirana mafunso okhudza Kirchhoff’s Law.

1. Dera lamagetsi limakhala ndi zotsutsana zinayi, chilichonse R 1 = 6 Ohm, R 2 = 6 Ohm, R 3 = 9 Ohm ndi R 4 = 3 Ohm cholumikizidwa ndi E 1 = 6 Volt, E 2 = 12 Volt monga momwe zasonyezedwera pachithunzi chotsatirachi. Mphamvu yamagetsi ikuyenda….

Zokambirana

Amadziwika kuti:
Wotsutsa 1 (R)1) = 6 Ω
Wotsutsa 2 (R)2) = 6 Ω
Wotsutsa 3 (R)3) = 9 Ω
Wotsutsa 4 (R)4) = 3 Ω
Gwero la emf 1 (E)1) = 6 Volt
Gwero la emf 2 (E)2) = 12 Volt
Anafunsa kuti: Mphamvu yamagetsi yomwe ikuyenda mu dera (I)

Chitsanzo cha mavuto otsutsana ndi parallel resistor

Zitsanzo 4 za Mavuto Otsutsana ndi Parallel

Komanso phunzirani zomwe zili pa ma resistors ofanana ndi zitsanzo za mavuto a resistor otsatizana , zitsanzo za mavuto a kukana magetsi.

1. Popeza R 1 = 2 Ω ndi R 2 = 4 Ω zalumikizidwa motsatizana. Kodi mtengo wa resistor yolowa m'malo ndi wotani? (Ω = Ohm).

Zokambirana

1/R = 1/R 1 + 1/R 2 = 1/2 + 1/4 = 2/4 + 1/4 = 3/4

R = 4/3 Ω

Mtengo wa kukana kolowa m'malo ndi waukulu kuposa mtengo wa chokana chilichonse cholumikizidwa motsatizana.

2.R1 = 1 Ω, R2 = 2 Ω, R3 = 3 Ω. Mtengo wosinthira resistor ndi…..Chitsanzo 1 cha resistor yofanana

Chitsanzo cha mavuto a resistor otsatizana

Zitsanzo 4 za Mavuto a Otsutsa Otsatizana

Komanso phunzirani zinthu zotsutsana ndi mndandanda ndi zitsanzo za mavuto otsutsana ndi mzere.

1. Popeza R 1 = 2 Ω ndi R 2 = 4 Ω zalumikizidwa motsatizana. Kodi mtengo wa resistor yolowa m'malo ndi wotani? (Ω = Ohm).

Zokambirana

R = R 1 + R 2 = 2 + 4 = 6 Ω.

Mtengo wa kukana kolowa m'malo ndi waukulu kuposa mtengo wa chokana chilichonse cholumikizidwa motsatizana.

2. R 1 = 1 Ω, R 2 = 2 Ω, R 3 = 3 Ω. Mtengo wosinthira wa resistor ndi…..

Chitsanzo cha mafunso okhudza kukana magetsi

Komanso phunzirani zinthu zokhudzana ndi kukana kwamagetsi , zitsanzo za mavuto a resistor otsatizana , zitsanzo za mavuto a resistor ofanana.

Zitsanzo ziwiri za Mafunso Otsutsana ndi Magetsi

1. Chipangizo chamagetsi chimalumikizidwa ku gwero lamagetsi la 30 Volt ndipo chimakhala ndi mphamvu ya ma Ampere awiri. Dziwani kukana kwamagetsi kwa chipangizocho!

Zokambirana

Amadziwika kuti:

Mphamvu yamagetsi (V) = 30 Volts

Mphamvu yamagetsi (I) = 2 Ampere

Funso: Kukana kwa magetsi (R)

Yankho:

Fomula yotsutsa magetsi:
