Haeba ho na le mehloli e 'meli kapa ho feta ea electromotive (emf) e hokahaneng joalo ka ha ho bontšitsoe setšoantšong, emf e hlophisitsoe ka tatellano.

E lekanang Palo ea li-volts mohloli (ε) ke:

ε = ε₁ + ε₂ + ε_n

Khanyetso e lekanang ea kahare (r) ke:

r = r₁ +r₂ +r_n

Motlakase o phallang ka khanyetso ea kantle (R) ke:

ke = ε / (r + R)

Bothata ba mohlala:

A re re libeteri tse peli tsa emf ka 'ngoe ke 1.5 Volt 'me boleng ba khanyetso ea kahare ho betri ka 'ngoe ke 0.1 Ω. Khanyetso ea kantle (R) = 10 Ω. Tsela ea motlakase oa motlakase ho ea ka oache.

Sebelisa foromo e fetileng:

ε = 1.5 + 1.5 = 3 Volt

r = 0.1 + 0.1 = 0.2 Ω

Ke = ε / (r + R) = 3 / (0.2 + 10)

Ke = 3 / 10.2

Ke = 0.294 A

Sebelisa molao oa bobeli oa 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

Ke = 3 / 10.2

Ke = 0.294 A

Haeba ho na le mehloli e 'meli kapa ho feta ea electromotive (emf) e hokahaneng joalo ka ha ho bontšitsoe setšoantšong, emf e hokahantsoe ka ho lekana.

Mohloli o lekanang oa motlakase (ε) ke:

ε = ε₁ = ε₂ = ε_n

Khanyetso e lekanang ea kahare (r) ke:

1/r = 1/r₁ + 1/r₂ + 1/r_n

Motlakase o phallang ka khanyetso ea kantle (R) ke:

ke = ε / (r + R)

Bothata ba mohlala:

A re re libeteri tse peli tsa emf ka 'ngoe ke 1.5 Volt 'me boleng ba khanyetso betring ka 'ngoe ke 0.1 Ω. Khanyetso ea kantle (R) = 10 Ω.

Sebelisa foromo e fetileng:

ε = 1.5 Volt

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

r = 0.1 / 2 = 0.05 Ω

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

Ke = 0.149 A

Sebelisa molao oa Kirchhoff

Etsa kopo KirchhoffMolao oa pele:

I₁ + Ke₂ = KE ………. Tekanyo 1

Sekaseka sekotwana sa Aefca. Tsela eo sekotwana se tsamayang ka yona e ya ka watjhe. Sebedisa molao wa bobedi wa Kirchhoff:

ε₂ - Ke₁ r₂ – IR = 0

1.5 – 0.1 I₁ – 10 I = 0

– 0.1 I₁ = 10 I – 1.5

I₁ = (10 I – 1.5) / – 0.1

I₁ = -100 I + 15 ………. Tekolo 2

Sekaseka sekotwana sa Befdb. Tsela eo sekotwana se tsamayang ka yona e ya ka watjhe. Sebedisa molao wa bobedi wa Kirchhoff:

ε₁ - Ke₂ r₁ – IR = 0

1.5 – 0.1 I₂ – 10 I = 0

- 0.1 Ke₂ = 10 I – 1.5

I₂ = (10 I – 1.5) / – 0.1

I₂ = -100 I + 15 ………. Tekolo 3

Kenya diekate tsa 2 le 3 sebakeng sa ekate ya 1:

I₁ + Ke₂ = KE

-100 I + 15 – 100 I + 15 = I

– 200 I + 30 = I

30 = Ke + 200 Ke

30 = 201 I

Ke = 30 / 201

Ke = 0.149 A

Tlosa equation ea 2 le ea 3:

I₁ = -100 I + 15

I₂ = -100 I + 15

——————– –

I₁ - Ke₂ = 0

I₁ = KE₂ ………. Tekanyo 4

Hobane ke₁ + Ke₂ = Nna, moo ke₁ = KE₂ joale ke₁ = KE₂ = 1/2 I = 1/2 (0.149) = 0.0745 A.
