R1, R2 iyo R3 Isku xiran si is barbar socda. Iska-caabinta beddelka ah waa:
1 / R123 = 1 /R1 + 1/R2 + 1/R3 = 1/9 + 1/9 + 1/9 = 3/9
R123 = 9/3 = 3 Ω
R123 iyo R4 Isku xiran taxane ahaan. Resistor-ka beddelka ah waa:
R = R123 + R4 = 3 Ω + 2 Ω
R = 5 Ω
Jawaab D
R 1 = 5 Ω, R 2 = 10 Ω, R 3 = 2 Ω, R 4 = 2 Ω
R1 iyo R2 Isku xiran si is barbar socda. Iska-caabinta beddelka ah waa:
1/R 12 = 1/R 1 + 1/R 2 = 1/5 + 1/10 = 2/10 + 1/10
1/R 12 = 3/10
R12 = 10 / 3 Ω
R3 iyo R4 Isku xiran si is barbar socda. Iska-caabinta beddelka ah waa:
1 / R34 = 1/R3 + 1/R4 = 1/2 + 1/2 = 2/2
R34 = 1 Ω
R12 iyo R34 Isku xiran taxane ahaan. Resistor-ka beddelka ah waa:
R = R12 + R34 = 10/3 + 3/3 = 13/3
R = 4,3 Ω
Jawaabta saxda ah waa A.
2. Iska caabinta u dhiganta sawirka hoose waa…
A. 26 Ohm
B. 16 Ohms
C. 15 Ohms
D. 11 Ohm
Iska caabbinta 6 Ω, 3 Ω iyo 2 Ω waxay ku xiran yihiin is barbar socda. Iska caabbinta beddelka ah waa:
1 / RP = 1/6 + 1/3 + 1/2 = 1/6 + 2/6 + 3/6 = 6/6
RP = 6/6 = 1 Ω
Iska caabbinta 7 Ω, 8 Ω, iyo 1 Ω waxay ku xiran yihiin taxane. Iska caabbinta beddelka ah waa:
R = 7 + 8 + 1 = 16 Ω
Jawaabta saxda ah waa B.
3. Immisa Rp ayaa ku jira wareegga isku dhafan ee hoose?
A. 8 ohms
B. 1/8 ohm
C. 1 ohms
D. 7 ohms
Dood
Waa la ogyahay in:
Iska caabbiye 1 (R 1 ) = 2 Ohm
Iska caabbiye 2 (R 2 ) = 2 Ohm
Iska caabbiye 3 (R 3 ) = 2 Ohm
Iska caabbiye 4 (R 4 ) = 2 Ohm
La weydiiyay: Iska-caabinta beddelka ah
Jawaab:
Iska caabbiye R2 iyo iska caabinta R3 isku xiran si is barbar socda. Iska-caabinta beddelka ah:
1/R 23 = 1/R 2 + 1/R 3
1 / R23 = 1/2 + 1/2 = 2/2
R 23 = 1 Ohm
Iska caabbiye R1, iska caabbiye R23 iyo iska caabinta R3 ku xiran taxane. Iska-caabinta beddelka:
R = R1 + R2 + R3 = 2 + 1 + 2
R = 5 Ohm
Jawaabta saxda ah waa 5 ohms.
