Sidoo kale baro agabka ku saabsan iska caabinta isbarbar socda iyo tusaalooyinka dhibaatooyinka iska caabinta taxanaha ah , tusaalooyinka dhibaatooyinka iska caabinta korontada.

1. Maadaama R ₁ = 2 Ω iyo R ₂ = 4 Ω ay isku xiran yihiin si is barbar socda. Waa maxay qiimaha iska caabbinta beddelka ah? (Ω = Ohm).

Dood

1/R = 1/R ₁ + 1/R ₂ = 1/2 + 1/4 = 2/4 + 1/4 = 3/4

R = 4/3 Ω

Qiimaha iska caabbinta beddelka ah ayaa ka weyn qiimaha iska caabbinta kasta oo ku xiran taxane.

2.R₁ = 1 Ω, R₂ = 2 Ω, R₃ = 3 Ω. Qiimaha iska caabbinta beddelka ah waa…..

Dood

1/R = 1/R ₁ + 1/R ₂ + 1/R ₃ = 1/1 + 1/2 + 1/3 = 6/6 + 3/6 + 2/6 = 11/6

R = 6/11 Ω.

3. R _{​​​​1} = 4 Ω, R ₂ = 2 Ω, V = 12 Volts. Go'aami (a) qiimaha iska caabbinta beddelka ah (b) qulqulka korantada ee wareegga ku socda (c) qulqulka korontada ee dhex maraya iska caabbinta R ₁ iyo R ₂

Dood

(a) Iska caabbinta beddelka ah

1/R = 1/R ₁ + 1/R ₂ = 1/4 + 1/2 = 1/4 + 2/4 = 3/4

R = 4/3 Ω.

(b) Koronto ku jirta wareegga

I = V / R = 12: 4/3 = 12 x 3/4 = 9 Amperes

(c) Koronto koronto oo dhex marta iska caabbinta R ₁ iyo R ₂

Farqiga suurtagalka ah ee labada daraf ee R ₁ = farqiga suurtagalka ah ee labada daraf ee R ₂ = 12 Volts.

I ₁ = V / R ₁ = 12 / 4 = 3 Amperes

I ₂ = V / R ₂ = 12 / 2 = 6 Amperes

Natiijadani waxay waafaqsan tahay sharciga ugu horreeya ee Kirchhoff :

Aniga = Aniga ₁ + Aniga ₂

9 A = 3 A + 6 A

4. R₁ = 2 Ω, R₂ = 4 Ω, R₃ = 6 Ω, R₄ = 8 Ω, V = 12 Volts. Go'aami (a) Qiimaha iska caabbinta beddelka ah (b) Korontada ku socota wareegga (c) Korontada ku socota iska caabbinta R₂ (d) Danabka korontada ee labada daraf ee iska caabbinta R₄.

Dood

(a) Iska caabbinta beddelka ah

1/R = 1/R ₁ + 1/ R ₂ + 1/R ₃ + 1/R ₄ = 1/2 + 1/4 + 1/6 + 1/8 = 12/24 + 6/24 + 4/24 + 3/24 = 25/24

R = 24/25 Ω

(b) Koronto koronto oo dhex marta wareegga

I = V / R = 12: 24/25 = 12 x 25/24 = 1 x 25/2 = 12,5 A amper

(c) Koronto koronto oo dhex marta iska caabinta R_1, R₂, R₃, R₄

Farqiga suurtagalka ah ee labada daraf ee R ₁ = farqiga suurtagalka ah ee labada daraf ee R ₂ = farqiga suurtagalka ah ee labada daraf ee R ₃ = farqiga suurtagalka ah ee labada daraf ee R ₄ = 12 Volts.

I ₁ = V / R ₁ = 12 / 2 = 6 Amperes

I ₂ = V / R ₂ = 12 / 4 = 3 Amperes

I ₃ = V / R ₃ = 12 / 6 = 2 Amperes

I ₄ = V / R ₄ = 12 / 8 = 1,5 Amperes

Natiijadani waxay waafaqsan tahay sharciga ugu horreeya ee Kirchhoff:

Aniga = Aniga ₁ + Aniga ₂

12,5 A = 6 A + 3 A + 2 A + 1,5 A

(D)

Farqiga suurtagalka ah ee labada daraf ee R ₁ = farqiga suurtagalka ah ee labada daraf ee R ₂ = farqiga suurtagalka ah ee labada daraf ee R ₃ = farqiga suurtagalka ah ee labada daraf ee R ₄ = 12 Volts.
