Laʻana o nā pilikia resistor like

4 mau laʻana o nā pilikia resistor parallel

E aʻo pū i nā mea ma nā resistors parallel a me nā laʻana o nā pilikia resistor series , nā laʻana o nā pilikia kū'ē uila.

1. Hāʻawi ʻia ua pili like ʻo R ₁ = 2 Ω a me R _{2 = 4 Ω. He aha ka waiwai o ke kū'ē pani? (Ω = Ohm).}

Pahana

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

R = 4/3 Ω

ʻOi aku ka waiwai o ke kū'ē pani ma mua o ka waiwai o kēlā me kēia resistor i hoʻopili ʻia ma ke ʻano he moʻo.

2.R₁ = 1 Ω, R₂ = 2 Ω, R₃ = 3 Ω. ʻO ke kumukūʻai o ke kū'ē pani he…..

Pahana

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. E hoʻoholo i (a) ka waiwai o ke kū'ē pani (b) ke au uila e kahe ana i loko o ke kaapuni (c) ke au uila e hele ana ma o nā kū'ē R ₁ a me R ₂

Pahana

(a) Palekana pani

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

R = 4/3 Ω.

(b) Ke au uila i loko o ke kaapuni

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

(c) Ke au uila e hele ana ma o nā resistors R ₁ a me R ₂

ʻOkoʻa hiki ma nā wēlau ʻelua o R ₁ = ʻokoʻa hiki ma nā wēlau ʻelua o R ₂ = 12 Volts.

ʻO I ₁ = V / R ₁ = 12 / 4 = 3 Amperes

ʻO I ₂ = V / R ₂ = 12 / 2 = 6 Amperes

Ua kūlike kēia hopena me ke kānāwai mua o Kirchhoff :

ʻO wau = ʻO wau ₁ + ʻO wau ₂

9 A = 3 A + 6 A

4. R₁ = 2 Ω, R₂ = 4 Ω, R₃ = 6 Ω, R₄ = 8 Ω, V = 12 Volts. E hoʻoholo (a) Ka waiwai o ke kū'ē pani (b) Ke au uila e kahe ana i loko o ke kaapuni (c) Ke au uila e kahe ana ma o ke kū'ē R₂ (d) ʻO ke ana uila ma nā wēlau ʻelua o ke kū'ē R₄.

Pahana

(a) Palekana pani

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) Ke au uila e hele ana ma o ke kaapuni

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

(c) Ke au uila e hele ana ma o ke kū'ē R_1, R₂, R₃, R₄

ʻOkoʻa hiki ma nā wēlau ʻelua o R ₁ = ʻokoʻa hiki ma nā wēlau ʻelua o R ₂ = ʻokoʻa hiki ma nā wēlau ʻelua o R ₃ = ʻokoʻa hiki ma nā wēlau ʻelua o R ₄ = 12 Volts.

ʻO I ₁ = V / R ₁ = 12 / 2 = 6 Amperes

ʻO I ₂ = V / R ₂ = 12 / 4 = 3 Amperes

ʻO I ₃ = V / R ₃ = 12 / 6 = 2 Amperes

ʻO I ₄ = V / R ₄ = 12 / 8 = 1,5 Amperes

Ua kūlike kēia hopena me ke kānāwai mua o Kirchhoff:

ʻO wau = ʻO wau ₁ + ʻO wau ₂

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

(d)

ʻOkoʻa hiki ma nā wēlau ʻelua o R ₁ = ʻokoʻa hiki ma nā wēlau ʻelua o R ₂ = ʻokoʻa hiki ma nā wēlau ʻelua o R ₃ = ʻokoʻa hiki ma nā wēlau ʻelua o R ₄ = 12 Volts.
