Mphamvu yamagetsi yotsatizana ndi yofanana (EMF)

Zida zamphamvu zamagetsi (EMF) zotsatizana komanso zofanana

Ngati pali magwero awiri kapena oposa awiri a magetsi (emf) olumikizidwa monga momwe zilili pachithunzi cha mbali, emf imalumikizidwa motsatizana.

Gwero la magetsi (ε) cholowa m'malo ndi:

ε = ε₁ + ndi₂ + ndi_n

Kukana mu (r) kusintha ndi:

r = r₁ +r₂ +r_n

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

I = ε / (r + R)

Chitsanzo cha mavuto:

MTiyerekeze kuti mabatire awiri aliwonse ali ndi mphamvu ya 1,5 Volts ndipo Mtengo wotsutsa mu batire iliyonse ndi 0,1 O! Kukana kwakunja (R) = 10 Ω. Kulunjika kwa mphamvu yamagetsi kumayenda mozungulira wotchi.

Gwiritsani ntchito fomula yapitayi :

ε = 1,5 + 1,5 = Ma Volti 3

r = 0,1 + 0,1 = 0,2 Ω

I = ε / (r + R) = 3 / (0,2 + 10)

Ine = 3/10,2

I = 0,294 Ampere

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

I = 0,294 Ampere 

Ngati pali magwero awiri kapena oposa awiri a magetsi (emf) olumikizidwa monga momwe zilili pachithunzi cha mbali, emf imalumikizidwa motsatizana.

Sgwero la magetsi amagetsi (ε) cholowa m'malo ndi:

ε = ε₁ = ε₂ = ε_n

Kukana mu (r) kusintha ndi:

1/r = 1/r₁ + 1/r₂ + 1/r_n

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

I = ε / (r + R)

Chitsanzo cha mavuto:

Tiyerekeze kuti mabatire awiri aliwonse ali ndi mphamvu ya 1,5 Volts ndipo Mtengo wotsutsa mu batire iliyonse ndi 0,1 Ω . Kukana kwakunja (R) = 10 Ω.

Gwiritsani ntchito fomula yapitayi :

ε = Ma Volti 1,5

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

I = 0,149 Ampere

Gwiritsani ntchito lamulo la Kirchhoff

Gwiritsani ntchito lamulo loyamba la Kirchhoff:

I₁ + I₂ = Ine .......... Chiyerekezo 1

Kusanthula loop aefca. Njira yozungulira ndi yozungulira wotchi. Gwiritsani ntchito lamulo lachiwiri la Kirchhoff:

ε₂ - ine₁ r₂ - ine R = 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 Ine + 15 ………. Chiyerekezo 2

Kusanthula kwa kuzungulira patsogolo pa db. Njira yozungulira ndi yozungulira wotchi. Gwiritsani ntchito lamulo lachiwiri la Kirchhoff:

ε₁ - ine₂ r₁ - ine R = 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 Ine + 15 .......... Kufanana 3

Sinthani ma equation 2 ndi 3 kukhala equation 1:

I₁ + I₂ = Ine

-100 Ine + 15 - 100 Ine + 15 = ine

– 200 I + 30 = I

30 = Ine + 200 Ine

30 = 201 I

Ine = 30/201

I = 0,149 ampe

Chotsani ma equation 2 ndi 3:

I₁ = -100 Ine + 15

I₂ = -100 Ine + 15

——————– –

I₁ - ine₂ = 0

I₁ = Ine₂ .......... Kufanana 4

Chifukwa ine₁ + I₂ = Ine, kumene ine₁ = Ine₂ kenako ine₁ = Ine₂ = 1/2 I = 1/2 (0,149) = 0,0745 Ampere
