Ma EMF otsatizana komanso ofanana

Ngati pali magwero awiri kapena angapo a electromotive (emf) olumikizidwa monga momwe zasonyezedwera pachithunzichi, emf imakonzedwa motsatizana.

Chofanana Voteji gwero (ε) ndi:

ε = ε₁ + ndi₂ + ndi_n

Kukana kofanana kwamkati (r) ndi:

r = r₁ +r₂ +r_n

Mphamvu yamagetsi yomwe ikuyenda kudzera mu kukana kwakunja (R) ndi:

I = ε / (r + R)

Vuto la chitsanzo:

Tiyerekeze kuti mabatire awiri a emf iliyonse ndi 1.5 Volt ndipo mtengo wamkati wa batri iliyonse ndi 0.1 Ω. Kukana kwakunja (R) = 10 Ω. Kulunjika kwa mphamvu yamagetsi mozungulira wotchi.

Gwiritsani ntchito fomula yapitayi:

ε = 1.5 + 1.5 = 3 Volt

r = 0.1 + 0.1 = 0.2 Ω

I = ε / (r + R) = 3 / (0.2 + 10)

Ine = 3/10.2

Ine = 0.294 A

Gwiritsani ntchito lamulo lachiwiri la Kirchhoff:

1.5 – 0.1 I + 1.5 – 0.1 I – 10 I = 0

3 – 0.2 I – 10 I = 0

3 – 10.2 I = 0

3 = 10.2 I

Ine = 3/10.2

Ine = 0.294 A

Ngati pali magwero awiri kapena kuposerapo a electromotive (emf) olumikizidwa monga momwe zasonyezedwera pachithunzichi, emf imalumikizidwa motsatizana.

Gwero lofanana la magetsi (ε) ndi:

ε = ε₁ = ndi₂ = ndi_n

Kukana kofanana kwamkati (r) ndi:

1/r = 1/r₁ + 1/r₂ + 1/r_n

Mphamvu yamagetsi yomwe ikuyenda kudzera mu kukana kwakunja (R) ndi:

I = ε / (r + R)

Vuto la chitsanzo:

Tiyerekeze kuti mabatire awiri a emf iliyonse ndi 1.5 Volt ndipo mtengo wotsutsa mu batire iliyonse ndi 0.1 Ω. Kukana kwakunja (R) = 10 Ω.

Gwiritsani ntchito fomula yapitayi:

ε = 1.5 Volt

1/r = 1/0.1 + 1/0.1 = 2 / 0.1

r = 0.1 / 2 = 0.05 Ω

I = ε / (r + R) = 1.5 / (0.05 + 10) = 1.5 / 10.05

Ine = 0.149 A

Gwiritsani ntchito lamulo la Kirchhoff

Ikani KirchhoffLamulo loyamba la:

I₁ + I₂ = Ine ………. Chiyerekezo 1

Unikani kuzungulira kwa Aefca. Kulunjika kwa kuzungulirako kumayenda mozungulira wotchi. Gwiritsani ntchito lamulo lachiwiri la Kirchhoff:

ε₂ - ine₁ r₂ – IR = 0

1.5 – 0.1 I₁ – 10 I = 0

– 0.1 I₁ = 10 Ine – 1.5

I₁ = (10 I – 1.5) / – 0.1

I₁ = -100 I + 15 ………. Equation 2

Unikani kuzungulira kwa Befdb. Kulunjika kwa kuzungulirako kumayenda mozungulira wotchi. Gwiritsani ntchito lamulo lachiwiri la Kirchhoff:

ε₁ - ine₂ r₁ – IR = 0

1.5 – 0.1 I₂ – 10 I = 0

- 0.1 Ine₂ = 10 Ine – 1.5

I₂ = (10 I – 1.5) / – 0.1

I₂ = -100 I + 15 ………. Equation 3

Sinthani ma equation 2 ndi 3 kukhala equation 1:

I₁ + I₂ = Ine

-100 I + 15 – 100 I + 15 = I

– 200 I + 30 = I

30 = Ine + 200 Ine

30 = 201 I

Ine = 30/201

Ine = 0.149 A

Chotsani equation 2 ndi 3:

I₁ = -100 I + 15

I₂ = -100 I + 15

——————– –

I₁ - ine₂ = 0

I₁ = Ine₂ ………. Chiyerekezo 4

Chifukwa ine₁ + I₂ = Ine, kumene ine₁ = Ine₂ ndiye ine₁ = Ine₂ = 1/2 I = 1/2 (0.149) = 0.0745 A.
