Korontada ka soo baxda baytariga
Marka hore, xisaabi iska caabinta u dhiganta ( R). Intaa ka dib, xisaabi qulqulka korantada adoo isticmaalaya isle'egta sharciga Ohm :
V = IR ama I = V / R
V = danab , I = koronto , R = iska caabin u dhiganta
Iska caabinta u dhiganta:
Iska caabbinta R 1 iyo iska caabbinta R 2 waxay ku xiran yihiin is barbar socda . Iska caabbinta u dhiganta:
1/R 12 = 1/R 1 + 1/R 2 = 1/4 + 1/4 = 2/4
R 12 = 4/2 = 2 Ω
Resistor R 12 iyo resistor R 3 waxay ku xiran yihiin taxane . Iska caabinta u dhiganta:
R = R 12 + R 3 = 2 + 8 = 10 Ω
Korontada ka soo baxda baytariga:
I = V / R = 40 / 10 = 4 A
Korontada ka soo baxda baytariga waa 4 Ampere.
Danabka korontada V ab iyo V bc
KirchhoffXeerka ugu horreeya ee waxay sheegaysaa in marka Bar kasta oo isku xir ah, wadarta dhammaan qulqulka soo galaya isgoyska waa inay la mid noqotaa wadarta dhammaan qulqulka ka baxaya isgoyska.
Iyada oo lagu saleynayo qaanuunka ugu horreeya ee Kirchhoff , waxaa lagu soo gabagabeynayaa haddii qulqulka korontadu ka soo baxo baytariga uu yahay 4 A markaas qulqulka korontadu ee dhex mara ab wuxuu la mid yahay 4 Ampere, sidaas oo kale qulqulka korontadu ee dhex mara bc waa 4 Ampere.
Danabka korontada V ab :
V ab = I ab R ab = (4)(2) = 8 Volts
Danabka korontada V bc :
V bc = I bc R bc = (4)(8) = 32 Volts
Wareegga kor ku xusan wuxuu ku xiran yahay taxane si danab koronto oo dhan uu u noqdo V = V ab + V bc = 8 Volts + 32 Volts = 40 Volts.
Korontadu waxay dhex martaa R 1 = 4 Ω
I 1 = V ab / R 1 = 8 Volts / 4 Ohms = 2 A
I 2 = V ab / R 2 = 8 Volts / 4 Ohms = 2 A
Korontada ka soo baxda baytariga waa 4 A. Marka ay timaado barta korontada waxaa loo qaybiyaa laba, korontadu waxay ku socotaa iska caabbinta R 1 iyo
Korontada 2 A waxay dhex martaa iska caabbinta R 2. 2 A + 2 A = 4 A.
2. Iyada oo ku saleysan sawirka hoose, go'aami qulqulka korantada ee dhex mara iska caabinta 4-Ω.
La yaqaan:

Iska caabbinta 2 (R 2 ) = 4 Ω
Iska caabbinta 3 (R 3 ) = 1.6 Ω
Danabka korontada (V) = 16 Volts
La Raadinayo: Korontadu waxay dhex martaa 4 Ω
Xalka:
Korontadu waxay ka socotaa awood sare ilaa awood hoose. Jihada hadda korontada ee wareegga kore waxay la mid tahay jihada saacad u socota.
Korontada ka soo baxda baytariga
Iska caabinta u dhiganta:
Resistor R 1 iyo resistor R 2 waxay ku xiran yihiin is barbar socda. Resistor-ka u dhigma:
1/R 12 = 1/R 1 + 1/R 2 = 1/6 + 1/4 = 2/12 + 3/12 = 5/12
R 12 = 12/5 = 2.4 Ω
Resistor R 12 iyo resistor R 3 waxay ku xiran yihiin taxane. Resistor-ka u dhigma:
R = R 12 + R 3 = 2.4 + 1.6 = 4 Ω
Korontada ka soo baxda baytariga:
I = V / R = 16 / 4 = 4 A
Danabka korantada ee V ab iyo V bc
Iyada oo ku saleysan qaanuunka ugu horreeya ee Kirchhoff, waxay soo gabagabeysay in haddii korontada ka soo baxdo baytariga ay tahay 4 A markaas korontada dhex marta ab waxay la mid tahay 4 Ampere, sidaas oo kale korontada dhex marta bc waa 4 Ampere.
Danabka korantada ee V ab :
V ab = I ab R ab = (4)(2.4) = 9.6 Volts
Danabka korantada ee Vbc :
V bc = I bc R bc = (4)(1.6) = 6.4 Volts
Wareegga kor ku xusan wuxuu ku xiran yahay taxane si danab koronto oo dhan uu u noqdo V = V ab + V bc = 9.6 Volts + 6.4 Volts = 16 Volts.
Korontada ku socota R 2 = 4 Ω
I 1 = V ab / R 1 = 9.6 Volts / 6 Ohms = 1.6 A
I 2 = V ab / R 2 = 9.6 Volts / 4 Ohms = 2.4 A
Korontada ka soo baxda baytariga waa 4 A. Marka ay timaado barta korontada waxaa loo qaybiyaa laba,
Korontada 1.6 A waxay dhex martaa iska caabbinta R 1 halka korontadu 2.4 A ay dhex marto iska caabbinta R 2. 1.6 A + 2.4 A = 4 A.
