Maqaal ku saabsan Resistors-ka taxanaha ah
Haddii iska caabintu ay isku xiran yihiin sida ku cad sawirka, iska caabintu waxay u habaysan yihiin taxane. Iska caabinta ama iska caabinta korontada ee su'aasha laga qabo waxay noqon kartaa qaab qaybaha iska caabinta, nalalka, ama iska caabinta korontada kale.
Dareeraha korontadu wuxuu dhex maraa iska caabinta 1 (R)1) = ah kharash koronto wuxuu dhex maraa iska caabinta 2 (R)2) = dallacaadda korontadu waxay dhex martaa iska caabbinta 3 (R3). Korantada hada jirta (I) waa koronto koronto oo socota muddo cayiman (I = Q / t), sidaas darteedna qulqulka korontada ee dhex mara iska caabinta 1 (I1) = koronto koronto oo dhex marta iska caabinta 2 (I2) = koronto koronto oo dhex marta iska caabinta 3 (I3Xisaab ahaan, wadarta guud ee korantada (I) = I1 = Aniga2 = Aniga3.
Taas beddelkeeda, danabka korontada (V) wuu yaraadaa marka danabka korontada uu dhex maro iska caabin kasta. Danabka korontada oo sidoo kale loo yaqaan kala duwanaanshaha danabka korontada, waa tamar awood koronto oo halbeeg ah oo danabka korontada ah. Danabka korontada waa la dhimaa sababtoo ah korontada waxaa loo isticmaalaa iska caabin koronto kasta. Markaa, danabka korontada oo dhan (V) wuxuu la mid yahay qadarka korontada ee ku jira iska caabin kasta. Xisaab ahaan, danabka korontada oo dhan (V) = V1 +V2 +V3V = IR markaa isle'egta danabka korontadu waa V = IR1 + IR2 + IR3Korontada ku socota iska caabin kasta waa la mid tahay si isla'egtan ay isu beddesho V = I (R1 + R2 + R3).
Iyada oo lagu saleynayo isla'egta kor ku xusan, waxaa lagu soo gabagabeyn karaa in isku-darka guud ee iska caabbinta korantada (R) ama iska caabbinta u dhiganta ee iska caabbinta korantada
kaas oo isku xiran taxane ahaan wuxuu la mid yahay wadarta iska caabin kasta oo koronto, xisaab ahaan R = R1 + R2 + R3Haddii ay jiraan laba iska caabin oo taxane ah, iska caabinta u dhiganta (R) = R1 + R2Haddii ay jiraan afar iska caabin oo taxane ah, iska caabinta u dhiganta (R) = R1 + R2 + R3 + R4Sidoo kale, haddii ay jiraan shan ama in ka badan oo iska caabin ah oo isku xiran taxane ahaan.
Muunad dhibaato 1aad:
Haddii la yaqaan, R 1 = 2 Ω, R 2 = 3 Ω iyo R 3 = 4 Ω. Saddexda iska caabinba waxay ku xiran yihiin taxane. Waa maxay qiimaha iska caabinta u dhiganta? (Ω = Ohm ).
Solution:
R = R 1 + R 2 + R 3 = 2 + 3 + 4 = 9 Ω.
Natiijadani waxay muujinaysaa in iska caabinta u dhiganta ay ka weyn tahay qiimaha iska caabinta ku xiran taxanaha.
Muunad dhibaato 2aad:
Laba iska caabin ah R 1 = 50 Ω iyo 50 Ω ayaa isku xiran oo ku xiran baytari 12 Volt ah. Go'aami
(a) Iska caabinta u dhiganta
(b) Koronto koronto oo dhex marta iska caabin kasta
Solution:
(a) R = R 1 + R 2 = 50 Ω + 50 Ω = 100 Ω.
(b) I = V / R = 12 Volts / 100 Ω = 0.12 A
