3 Nā laʻana o nā nīnau kaapuni resistor

1. ʻO ka moʻo o nā resistors ma lalo nei nona ka pale like nui loa ʻo ia...

Pahana

Pane A

R₁ = 2 Ω, R₂ = 2 Ω, R₃ = 6 Ω, R₄ = 6 Ω

R₃ a me R₄ i hoʻopili ʻia ma ke ʻano like. ʻO ke kū'ē pani:

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

R₃₄ = 6/2 = 3 Ω

R_1, R₂ a me R₃₄ i hoʻopili ʻia ma ke ʻano moʻo. ʻO ke kū'ē pani:

R = R₁ + R₂ + R₃₄ = 2 Ω + 2 Ω + 3 Ω

R = 7 Ω

Pane B

R₁ = 2 Ω, R₂ = 4 Ω, R₃ = 4 Ω, R₄ = 8 Ω

R₂ a me R₃ i hoʻopili ʻia ma ke ʻano moʻo. ʻO ke kū'ē pani:

R₂₃ = R₂ + R₃ = 4 Ω + 4 Ω = 8 Ω

R₂₃ a me R₄ i hoʻopili ʻia ma ke ʻano like. ʻO ke kū'ē pani:

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

R₂₃₄ = 8/2 = 4 Ω

R₁ a me R₂₃₄ i hoʻopili ʻia ma ke ʻano moʻo. ʻO ke kū'ē pani:

R = R₁ + R₂₃₄ = 2 Ω + 4 Ω

R = 6 Ω

Pane C

R₁ = 9 Ω, R₂ = 9 Ω, R₃ = 9 Ω, R₄ = 2 Ω

R_1, R₂ a me R₃ i hoʻopili ʻia ma ke ʻano like. ʻO ke kū'ē pani:

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

R₁₂₃ = 9/3 = 3 Ω

R₁₂₃ a me R₄ i hoʻopili ʻia ma ke ʻano moʻo. ʻO ke kū'ē pani:

R = R₁₂₃ + R₄ = 3 Ω + 2 Ω

R = 5 Ω

Pane D

R₁ = 5 Ω, R₂ = 10 Ω, R₃ = 2 Ω, R₄ = 2 Ω

R₁ a me R₂ i hoʻopili ʻia ma ke ʻano like. ʻO ke kū'ē pani:

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

1 / R₁₂ = 3 / 10

R₁₂ = 10 / 3 Ω

R₃ a me R₄ i hoʻopili ʻia ma ke ʻano like. ʻO ke kū'ē pani:

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

R₃₄ = 1 Ω

R₁₂ a me R₃₄ i hoʻopili ʻia ma ke ʻano moʻo. ʻO ke kū'ē pani:

R = R₁₂ + R₃₄ = 10/3 + 3/3 = 13/3

R = 4,3 Ω

ʻO A ka pane pololei.

2. ʻO ke kū'ē like ma ke kiʻi ma lalo nei…

A. 26 Ohm

B. 16 Ohms

C. 15 Ohms

D. 11 Ohm

Pahana

Hoʻopili ʻia nā mea pale 6 Ω, 3 Ω a me 2 Ω ma ke ʻano like. ʻO nā mea pale pani:

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

R_P = 6/6 = 1 Ω

Hoʻopili ʻia nā resistors 7 Ω, 8 Ω, a me 1 Ω ma ke ʻano he series. ʻO nā resistors pani:

R = 7 + 8 + 1 = 16 Ω

ʻO ka pane pololei ʻo B.

3. ʻEhia ke kumukūʻai o Rp ma ke kaapuni hui ma lalo nei?

A. 8 ohms

B. 1/8 ohm

C. 1 ohm

D. 7 ohms

Pahana

Ua ʻike ʻia:

Palekana 1 (R₁) = 2 Ohms

Palekana 2 (R₂) = 2 Ohms

Palekana 3 (R₃) = 2 Ohms

Palekana 4 (R₄) = 2 Ohms

Ua nīnau ʻia: Palekana pani

Pane:

Pale R₂ a me ke kū'ē R₃ pili like. Resistor pani:

1 / R₂₃ = 1/R₂ +1/R₃

1 / R₂₃ = 1/2 + 1/2 = 2/2

R₂₃ = 1 Ohms

Pale R₁, kū'ē R₂₃ a me ke kū'ē R₃ i hoʻopili ʻia ma ke ʻano moʻo. Resistor pani:

R = R₁ + R₂ + R₃ = 2 + 1 + 2

R = 5 Ohm

ʻO ka pane pololei he 5 Ohms.
