Te kaha hiko raupapa me te kaha hiko whakarara (EMF)

Rauemi kaha hiko (EMF) raupapa me te whakarara

Mena e rua, neke atu rānei i te rua ngā pūtake hiko (emf) e honoa ana pērā i te pikitia i te taha, ka honoa raupapa te emf.

Pūtake hiko hiko (ε) ko te whakakapinga ko:

ε = ε₁ + ε₂ + ε_n

Ko te ātete i roto i te whakakapinga (r) ko:

r = r₁ +r₂ +r_n

Ko te iahiko e rere ana i roto i te ātete o waho (R) ko:

Ahau = ε / (r + R)

Tauira raruraru:

MMe kī he 1,5 Volts te emf o ia pākahiko e rua, ā, Ko te uara ātete i roto i ia pākahiko he 0,1 Aue. Ātete ā-waho (R) = 10 Ω. Ko te ahunga o te iahiko he taha matau.

Whakamahia te tātai o mua :

ε = 1,5 + 1,5 = 3 Ngā Waohiko

r = 0,1 + 0,1 = 0,2 Ω

I = ε / (r + R) = 3 / (0,2 + 10)

I = 3/10,2

I = 0,294 Āmpere

Whakamahia Te ture tuarua a 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 ahau

I = 3/10,2

I = 0,294 Āmpere 

Mena e rua, neke atu rānei i te rua ngā pūtake hiko (emf) e hono ana pērā i te pikitia i te taha, ka honoa te emf ki te taha whakarara.

Spūtake o te ngaohiko hiko (ε) ko te whakakapinga ko:

ε = ε₁ = ε₂ = ε_n

Ko te ātete i roto i te whakakapinga (r) ko:

1/r = 1/r₁ + 1/r₂ + 1/r_n

Ko te iahiko e rere ana i roto i te ātete o waho (R) ko:

Ahau = ε / (r + R)

Tauira raruraru:

Me kī he 1,5 Volts te emf o ia pākahiko e rua, ā, Ko te uara ātete i roto i ia pākahiko he 0,1 Ω. Te parenga o waho (R) = 10 Ω.

Whakamahia te tātai o mua :

ε = 1,5 Ngā Waohiko

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 Āmpere

Whakamahia te ture a Kirchhoff

Whakamahia te ture tuatahi a Kirchhoff:

I₁ + Ko ahau₂ = Ahau .......... Whārite 1

Tātaritanga whanui aefca. Ko te ahunga o te takahuri he taha matau. Whakamahia te ture tuarua a Kirchhoff:

ε₂ - Ahau₁ r₂ - Ahau R = 0

1,5 – 0,1 ahau₁ – 10 I = 0

– 0,1 ahau₁ = 10 I – 1,5

I₁ = (10 I – 1,5 ) / – 0,1

I₁ = -100 Ko ahau + 15 …… Whārite 2

Tātaritanga porowhita i mua i te db. Ko te ahunga o te takahuri he taha matau. Whakamahia te ture tuarua a Kirchhoff:

ε₁ - Ahau₂ r₁ - Ahau R = 0

1,5 – 0,1 ahau₂ – 10 I = 0

- 0,1 Ko ahau₂ = 10 I – 1,5

I₂ = (10 I – 1,5) / – 0,1

I₂ = -100 Ko ahau + 15 .......... Te ōritetanga 3

Whakakapia ngā whārite 2 me te 3 ki te whārite 1:

I₁ + Ko ahau₂ = Ahau

-100 Ko ahau + 15 - 100 Ko ahau + 15 = Ahau

– 200 I + 30 = I

30 = I + 200 I

30 = 201 ahau

I = 30/201

Ahau = 0,149 Āpere

Whakakorea ngā whārite 2 me te 3:

I₁ = -100 Ko ahau + 15

I₂ = -100 Ko ahau + 15

——————– –

I₁ - Ahau₂ = 0

I₁ = Ahau₂ .......... Te ōritetanga 4

Nā te mea ko au₁ + Ko ahau₂ = Au, kei hea ahau₁ = Ahau₂ kātahi ahau₁ = Ahau₂ = 1/2 I = 1/2 (0,149) = 0,0745 Āpere
