R₂ ndi R₃ cholumikizidwa motsatizana. Choletsa cholowa m'malo ndi:

R ₂₃ = R ₂ + R ₃ = 4 Ω + 4 Ω = 8 Ω

R₂₃ ndi R₄ cholumikizidwa motsatizana. Chotsukira cholowa m'malo ndi:

1/R ₂₃₄ = 1/R ₂₃ + 1/R ₄ = 1/8 + 1/8 = 2/8

R ₂₃₄ = 8/2 = 4 Ω

R₁ ndi R₂₃₄ cholumikizidwa motsatizana. Choletsa cholowa m'malo ndi:

R = R ₁ + R ₂₃₄ = 2 Ω + 4 Ω

R = 6 Ω

Yankho C

R ₁ = 9 Ω, R ₂ = 9 Ω, R ₃ = 9 Ω, R ₄ = 2 Ω

R_1, R₂ ndi R₃ cholumikizidwa motsatizana. Chotsukira cholowa m'malo ndi:

1/R ₁₂₃ = 1/ R ₁ + 1/ R ₂ + 1/R ₃ = 1/9 + 1/9 + 1/9 = 3/9

R ₁₂₃ = 9/3 = 3 Ω

R₁₂₃ ndi R₄ cholumikizidwa motsatizana. Choletsa cholowa m'malo ndi:

R = R ₁₂₃ + R ₄ = 3 Ω + 2 Ω

R = 5 Ω

Yankho D

R ₁ = 5 Ω, R ₂ = 10 Ω, R ₃ = 2 Ω, R ₄ = 2 Ω

R₁ ndi R₂ cholumikizidwa motsatizana. Chotsukira cholowa m'malo ndi:

1/R ₁₂ = 1/R ₁ + 1/R ₂ = 1/5 + 1/10 = 2/10 + 1/10

1/R ₁₂ = 3/10

R ₁₂ = 10/3 Ω

R₃ ndi R₄ cholumikizidwa motsatizana. Chotsukira cholowa m'malo ndi:

1/R ₃₄ = 1/R ₃ + 1/R ₄ = 1/2 + 1/2 = 2/2

R ₃₄ = 1 Ω

R₁₂ ndi R₃₄ cholumikizidwa motsatizana. Choletsa cholowa m'malo ndi:

R = R ₁₂ + R ₃₄ = 10/3 + 3/3 = 13/3

R = 4,3 Ω

Yankho lolondola ndi A.

2. Kukana kofanana ndi komwe kuli pachithunzi chili pansipa ndi…

A. 26 Ohm

B. 16 Ohms

C. 15 Ohms

D. 11 Ohm

Zokambirana

Zotsutsa 6 Ω, 3 Ω ndi 2 Ω zimalumikizidwa motsatizana. Zotsutsa zolowa m'malo ndi izi:

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

R _P = 6/6 = 1 Ω

Ma resistors 7 Ω, 8 Ω, ndi 1 Ω amalumikizidwa motsatizana. Ma resistors olowa m'malo ndi awa:

R = 7 + 8 + 1 = 16 Ω

Yankho lolondola ndi B.

3. Kodi Rp ndi ndalama zingati mu mixed circuit yomwe ili pansipa?

A. 8 ohms

B. 1/8 ohm

C. 1 ohms

D. 7 ohms

Zokambirana

Amadziwika kuti:

Wotsutsa 1 (R1 ₎ = 2 Ohm

Wotsutsa 2 (R2 ₎ = 2 Ohm

Wotsutsa 3 (R3 ₎ = 2 Ohm

Wotsutsa 4 (R4 ₎ = 2 Ohm

Yafunsidwa: Choletsa chosinthira

Yankho:

Zotsutsa R2 _ndi R3 _{zimalumikizidwa} motsatizana. Zotsutsa zosinthira:

1/R ₂₃ = 1/R ₂ + 1/R ₃

1/R ₂₃ = 1/2 + 1/2 = 2/2

R ₂₃ = 1 Ohm

Resistor R1 _, resistor R23 _ndi resistor R3 _{zimalumikizidwa} motsatizana. Resistor zosinthira:

R = R ₁ + R ₂ + R ₃ = 2 + 1 + 2

R = 5 Ohm

Yankho lolondola ndi 5 Ohms.
