Waxyaabaha Iska caabinta Isbarbardhigga ah
Haddii iska caabintu ay isku xiran yihiin sida sawirka dhinaca ku qoran, iska caabintu waxay isku xiran yihiin si is barbar socda.
Dakhli korontadu waa la ilaaliyaa si dakhli korontadu (dakhli korontadu = dakhli korontadu ku socoto muddo waqti ah) oo galaya barta laanta ay la mid tahay dakhli korontadu ka baxayso barta laanta. Waxaa jira dhowr laamood si wadarta dakhli korontadu u socoto = wadarta dakhli korontadu ku socoto laan kasta. Xisaab ahaan I = I 1 + I 2 + I 3. Halka farqiga awoodda korantada ama danabka korontada (V) ee laan kasta uu leeyahay qiime isku mid ah.
I = V/R markaa isla'egta kore waxay isu beddeshaa I = V/R1 + V/R2 + V/R3Danabka korontadu wuxuu leeyahay qiime isku mid ah sidaa darteed isla'egtan waxay isu beddeshaa I = V (1/R)1 + 1/R2 + 1/R3). Haddii iska caabinta u dhiganta ay tahay 1/R markaas I = V (1/R). Sidaas darteed 1/R = 1/R1 + 1/R2 + 1/R3.
Wareegga barbar socda wuxuu leeyahay faa'iido ah in haddii uu hakadka ku yimaado hal iska caabin uu hakad galo, hadda uu sii socdo isagoo dhex maraya iska caabinta kale. Wareegga taxanaha ah, haddii uu hakadka ku yimaado hal iska caabin la joojiyo, dhammaan iska caabinta ma socon doonaan. Iska caabintu waxay noqon kartaa nalalka iftiinka, qaybaha iska caabinta, iyo qaybo kale.
Tusaale ka mid ah iska caabinta isbarbar socda:
1. Marka la eego R1 = 2 Ω, R2 = 3 Ω. Labada iska caabin ayaa isku xiran si is barbar socda. Waa maxay qiimaha iska caabinta beddelka ah? (Ω = Ohm).
Dood
1/R = 1/R1 + 1/R2 = 1/2 + 1/3 = 3/6 + 2/6 = 5/6
R = 6/5 = 1,2 Ω.
Natiijadani waxay muujinaysaa in qiimaha iska caabbinta beddelka ahi uu ka yar yahay qiimaha iska caabbinta kasta oo isku xiran oo is barbar socda.
2. Laba iska caabin ah R1 = 50 Ω iyo 50 Ω waxay ku xiran yihiin taxane iyo is barbar socda, waxayna ku xiran yihiin baytari 12 Volt ah. Go'aami (a) iska caabinta u dhiganta (b) qulqulka korantada ee dhex mara iska caabin kasta.
Dood
(A)
Wareegga taxanaha:
R = R 1 + R 2 = 50 Ω + 50 Ω = 100 Ω.
Wareegga is barbar socda:
1/R = 1/R1 + 1/R2 = 1/50 + 1/50 Ω = 2/50
R = 50/2 = 25 Ω
(B)
Wareegga taxanaha:
I = V / R = 12 Volts / 100 Ω = 0,12 Amperes
Wareegga is barbar socda:
I = V / R = 12 Volts / 25 Ω = 0,48 Amperes
Natiijooyinkani waxay muujinayaan in wadarta guud ee korantada ee ku socota wareegga barbar socda ay ka weyn tahay, halka wadarta guud ee korontada ee ku socota wareegga taxanaha ah ay ka yar tahay.
