Qalabka Iska caabinta Taxanaha
Haddii iska caabintu ay isku xiran yihiin sida ku cad jaantuska kore, waxay ku xiran yihiin taxane. Iska caabintu waxay noqon kartaa qaybaha iska caabinta, laambado, ama qalab kale oo dahaarka korontada ku shaqeeya.
Dakhli koronto (Q) waa mid joogto ah si dakhli koronto uu uga gudbo iska caabbinta 1 (R1 ) = dakhli koronto oo dhex mara iska caabbinta 2 (R2 ) = dakhli koronto oo dhex mara iska caabbinta 3 (R3 ) . Dakhli koronto (I) waa dakhli koronto oo dhex mara muddo cayiman (I = Q/t), sidaas darteed dakhli koronto oo dhex mara iska caabbinta 1 (I1 ) = dakhli koronto oo dhex mara iska caabbinta 2 (I2 ) = dakhli koronto oo dhex mara iska caabbinta 3 (I3 ) . Xisaab ahaan, dakhli koronto oo dhan (I) = I1 = I2 = I3.
Taas lidkeeda, danab koronto (V) wuu yaraadaa marka dallacaadda korontadu ay dhex marto iska caabin kasta. Danabka korontada, oo sidoo kale loo yaqaan farqiga awoodda korantada, waa tamarta awoodda korontada Halbeeg kasta oo koronto ah. Danabku wuu yaraadaa sababtoo ah tamarta korontada ayaa loo isticmaalaa iska caabin kasta oo koronto ah. Markaa wadarta danabka korontada (V) waxay la mid tahay wadarta danabka korontada ee iska caabin kasta. Xisaab ahaan, wadarta danabka korontada (V) = V1 +V2 +V3V = IR markaa wadarta guud ee isla'egta danabka korontada waa V = IR1 + IR2 + IR3Korontada ku socota iska caabin kasta waxay leedahay qiime isku mid ah sidaa darteed isla'egtan waxay isu beddeshaa V = I (R1 + R2 + R3).
Iyada oo lagu saleynayo isla'egta kore, waxaa lagu soo gabagabeyn karaa in isku-darka guud ee iska caabbinta korantada (R) ama iska caabbinta u dhiganta ee iska caabbinta korantada ee taxanaha ku xiran ay la mid tahay wadarta iska caabbinta korantada kasta, xisaab ahaan R = R1 + R2 + R3Haddii ay jiraan laba iska caabin oo keliya oo ku xiran taxane, markaa qiimaha iska caabinta beddelka ah (R) = R1 + R2Haddii ay jiraan afar iska caabin oo taxane ah oo isku xiran, markaa qiimaha iska caabinta beddelka ah (R) = R1 + R2 + R3 + R4Sidoo kale, haddii ay jiraan shan ama in ka badan oo iska caabin ah oo ku xiran taxane.
Tusaale ahaan dhibaatada iska caabinta taxanaha ah:
1. Marka la eego R1 = 2 Ω, R2 = 3 Ω iyo R3 = 4 Ω. Saddexda iska caabin ayaa isku xiran taxane ahaan. Waa maxay qiimaha iska caabinta beddelka ah? (Ω = Ohm).
Dood
R = R1 + R2 + R3 = 2 + 3 + 4 = 9 Ω.
Natiijadani waxay muujinaysaa in qiimaha iska caabbinta beddelka ahi uu ka weyn yahay qiimaha iska caabbinta ee iska caabbin kasta oo taxane ah oo ku xiran.
2. Laba iska caabin ah R1 = 50 Ω iyo R2 = 50 Ω oo ku xiran taxane oo ku xiran baytari 12 Volt ah. Go'aami (a) iska caabinta u dhiganta (b) qulqulka korantada ee dhex mara iska caabin kasta.
Dood
(a) R = R 1 + R 2 = 50 Ω + 50 Ω = 100 Ω.
(b) I = V / R = 12 Volts / 100 Ω = 0,12 Ampere
