R ₁₂ = 10/3 Ω

R₃ da kuma R₄ an haɗa shi a layi ɗaya. Resistor ɗin maye gurbin shine:

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

R ₃₄ = 1 Ω

R₁₂ da kuma R₃₄ An haɗa shi cikin jerin. Resistor ɗin maye gurbin shine:

R = R ₁₂ + R ₃₄ = 10/3 + 3/3 = 13/3

R = 4,3 Ω

Amsar da ta dace ita ce A.

2. Daidaiton juriya a cikin hoton da ke ƙasa shine…

A. 26 Ohm

B. 16 Ohm

C. 15 Ohm

D. 11 Ohm

Tattaunawa

An haɗa masu juriya 6 Ω, 3 Ω da 2 Ω a layi ɗaya. Masu juriyar maye gurbin sune:

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

R _P = 6/6 = 1 Ω

An haɗa masu juriya 7 Ω, 8 Ω, da 1 Ω a jere. Masu juriyar maye gurbin sune:
