EMFs dzakatevedzana uye dzakafanana

Kana paine manyuko maviri kana anopfuura e electromotive (emf) akabatana sezvakaratidzwa mumufananidzo, emf yakarongwa zvakatevedzana.

The yakaenzana voltage tsime (ε) ndiro:

ε = ε₁ + ε₂ + ε_n

Kupikisa kwemukati kwakaenzana (r) ndekwekuti:

r = r₁ +r₂ +r_n

Mwenje wemagetsi unoyerera kuburikidza nekudzivirira kwekunze (R) ndewekuti:

I = ε / (r + R)

Dambudziko remuenzaniso:

Ngatitii mabhatiri maviri emf yega yega iri 1.5 Volt uye kukosha kwekudzivirira kwemukati mubhatiri rega rega i0.1 Ω. Kudzivirira kwekunze (R) = 10 Ω. Kutungamira kwemagetsi emagetsi achitenderera wachi.

Shandisa fomura yapfuura:

ε = 1.5 + 1.5 = 3 Volt

r = 0.1 + 0.1 = 0.2 Ω

I = ε / (r + R) = 3 / (0.2 + 10)

Ini = 3 / 10.2

Ini = 0.294 A

Shandisa mutemo wechipiri waKirchhoff:

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

Ini = 3 / 10.2

Ini = 0.294 A

Kana paine manyuko maviri kana anopfuura e electromotive (emf) akabatana sezvakaratidzwa mumufananidzo, emf yakabatana zvakafanana.

Chitubu chemagetsi chakaenzana (ε) ndeichi:

ε = ε₁ = ε₂ = ε_n

Kupikisa kwemukati kwakaenzana (r) ndekwekuti:

1/r = 1/r₁ + 1/r₂ + 1/r_n

Mwenje wemagetsi unoyerera kuburikidza nekudzivirira kwekunze (R) ndewekuti:

I = ε / (r + R)

Dambudziko remuenzaniso:

Ngatitii mabhatiri maviri emf yega yega iri 1.5 Volt uye kukosha kwekudzivirira mubhatiri rega rega iri 0.1 Ω. Kudzivirira kwekunze (R) = 10 Ω.

Shandisa fomura yapfuura:

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

Ini = 0.149 A

Shandisa KirchhoffMutemo wekutanga:

I₁ + Ini₂ = Ini ……. Equation 1

Ongorora Aefca loop. Kwakananga loop kwakanangana newachi. Shandisa mutemo wechipiri waKirchhoff:

ε₂ - ini₁ 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 ………. Kuenzanisa 2

Ongorora denderedzwa reBefdb. Kwakananga denderedzwa iri kwakanangana newachi. Shandisa mutemo wechipiri waKirchhoff:

ε₁ - ini₂ r₁ – IR = 0

1.5 – 0.1 I₂ – 10 I = 0

- 0.1 Ini₂ = 10 I – 1.5

I₂ = (10 I – 1.5) / – 0.1

I₂ = -100 I + 15 ………. Kuenzanisa 3

Isa maequation 2 ne3 panzvimbo yeequation 1:

I₁ + Ini₂ = Ini

-100 I + 15 – 100 I + 15 = I

– 200 I + 30 = I

30 = Ini + 200 Ini

30 = 201 I

Ini = 30 / 201

Ini = 0.149 A

Bvisa equation 2 ne3:

I₁ = -100 I + 15

I₂ = -100 I + 15

——————– –

I₁ - ini₂ = 0

I₁ = Ini₂ ……. Equation 4

Nekuti ini₁ + Ini₂ = Ini, kwandinoenda₁ = Ini₂ ipapo ini₁ = Ini₂ = 1/2 I = 1/2 (0.149) = 0.0745 A.
