1. Usoro resistors dị n'okpuru nke nwere nguzogide nhata kachasị ukwuu bụ...

Mkparịta ụka

Azịza A

R₁ = 2 Ω, R₂ = 2Ω, R₃ = 6Ω, R₄ = 6 Ω

R₃ na R₄ ejikọtara na parallel. Ihe nnọchi resistor bụ:

1 / R₃₄ = 1/R₃ +1/R₄ = 1/6 + 1/6 = 2/6

R₃₄ = 6 / 2 = 3 Ω

R_1, R₂ na R₃₄ ejikọtara na usoro. Ihe nnọchi resistor bụ:

R= R₁ + R₂ + R₃₄ = 2 Ω + 2 Ω + 3 Ω

R = 7 Ω

Azịza B

R₁ = 2Ω, R₂ = 4Ω, R₃ = 4Ω, R₄ = 8 Ω

R₂ na R₃ ejikọtara na usoro. Ihe nnọchi resistor bụ:

R₂₃ = R₂ + R₃ = 4 Ω + 4 Ω = 8 Ω

R₂₃ na R₄ ejikọtara na parallel. Ihe nnọchi resistor bụ:

1 / R₂₃₄ = 1/R₂₃ +1/R₄ = 1/8 + 1/8 = 2/8

R₂₃₄ = 8 / 2 = 4 Ω

R₁ na R₂₃₄ ejikọtara na usoro. Ihe nnọchi resistor bụ:

R=R₁ + R₂₃₄ = 2 Ω + 4 Ω

R = 6 Ω

Azịza C

R₁ = 9Ω, R₂ = 9Ω, R₃ = 9Ω, R₄ = 2 Ω

R_1, R₂ na R₃ ejikọtara na parallel. Ihe nnọchi resistor bụ:

1 / R₁₂₃ = 1 /R₁ + 1/R₂ +1/R₃ = 1/9 + 1/9 + 1/9 = 3/9

R₁₂₃ = 9/3 = 3 Ω

R₁₂₃ na R₄ ejikọtara na usoro. Ihe nnọchi resistor bụ:

R=R₁₂₃ + R₄ = 3 Ω + 2 Ω

R = 5 Ω

Azịza D

R₁ = 5Ω, R₂ = 10Ω, R₃ = 2Ω, R₄ = 2 Ω

R₁ na R₂ ejikọtara na parallel. Ihe nnọchi resistor bụ:

1 / R₁₂ = 1/R₁ +1/R₂ = 1/5 + 1/10 = 2/10 + 1/10

1 / R₁₂ = 3 / 10

R₁₂ = 10 / 3 Ω

R₃ na R₄ ejikọtara na parallel. Ihe nnọchi resistor bụ:

1 / R₃₄ = 1/R₃ +1/R₄ = 1/2 + 1/2 = 2/2

R₃₄ = 1 Ω

R₁₂ na R₃₄ ejikọtara na usoro. Ihe nnọchi resistor bụ:

R=R₁₂ + R₃₄ = 10/3 + 3/3 = 13/3

R = 4,3 Ω

Azịza ziri ezi bụ A.

2. Nguzogide nhata dị na foto dị n'okpuru bụ…

A. 26 Ohm

B. 16 Ohms

C. 15 Ohms

D. 11 Ohm

Mkparịta ụka

Njikọta resistors 6 Ω, 3 Ω na 2 Ω n'otu oge. Resistors nnọchi bụ:

1 / R_P = 1/6 + 1/3 + 1/2 = 1/6 + 2/6 + 3/6 = 6/6

R_P = 6/6 = 1 Ω

A na-ejikọ resistors 7 Ω, 8 Ω, na 1 Ω n'usoro. Resistors ndị nnọchi bụ:

R = 7 + 8 + 1 = 16 Ω

Azịza ziri ezi bụ B.

3. Ego ole ka Rp dị na sekit agwakọtara n'okpuru?

A. 8 ohms

B. 1/8 ohm

C. 1 ohm

D. 7 ohms

Mkparịta ụka

A maara na:

Resistor 1 (R)₁) = 2 Ohms

Resistor 2 (R)₂) = 2 Ohms

Resistor 3 (R)₃) = 2 Ohms

Resistor 4 (R)₄) = 2 Ohms

A jụrụ: Ihe nnọchi anya

Azịza:

Nguzogide R₂ na ihe mgbochi R₃ ejikọtara na n'otu oge. Nguzogide nnọchi:

1 / R₂₃ = 1/R₂ +1/R₃

1 / R₂₃ = 1/2 + 1/2 = 2/2

R₂₃ = 1

Nguzogide R₁, ihe mgbochi R₂₃ na ihe mgbochi R₃ ejikọtara na usoro. Resistor nnọchi:

R=R₁ + R₂ + R₃ = 2 + 1 + 2

R = 5 Ohm

Azịza ziri ezi bụ 5 Ohms.
