Sharciga Ohm
Mid ka mid ah mabaadi'da aasaasiga ah ee loo isticmaalo qeexidda qulqulka korantada waa Sharciga Ohm. Sharcigani wuxuu dhigayaa, "Halweerka dhex mara koronto-qaadaha u dhexeeya laba dhibcood wuxuu si toos ah ugu dhigmaa danabka labada dhibcood ka gudba wuxuuna si liddi ku ah u dhigmaa iska caabinta." Qaacidda xisaabta ee Sharciga Ohm waa:

\[ R_{\text{total}} = R_1 + R_2 = 6 \text{Ω} + 4 \text{Ω} = 10 \text{Ω} \]
Isticmaal qaacidada Sharciga Ohm:
\[ I = \frac{V}{R_{\text{total}}} \]

Marka hore, xisaabi wadarta iska caabbinta \( R_{\text{total}} \) ee iska caabbinta isku xiran iyadoo la adeegsanayo qaacidada:
\[ \frac{1}{R_{\text{total}}} = \frac{1}{R_1} + \frac{1}{R_2} \]
Halkee:
– \( R_1 = 8 \qoraal{Ω} \),

Isticmaal qaacidada Sharciga Ohm:
\[ I = \frac{V}{R_{\text{total}}} \]
Halkee:
– \( V = 12 \qoraal{ V} \),
– \( R_{\text{total}} \qiyaastii 2.67 \text{Ω} \).
\[ I \qiyaastii \frac{12 \text{ V}}{2.67 \text{ Ω}} \qiyaastii 4.49 \text{ A} \]

Su'aal Tusaale ah 6: Adeegsiga Sharciga Kirchoff
Sharciga Kirchoff
Waxaa jira laba sharci oo Kirchoff ah oo inta badan loo isticmaalo falanqaynta wareegga korantada:
1. Sharciga Hadda ee Kirchoff (KCL): Tirada hadda soo galaysa dhibic waxay la mid tahay tirada hadda ka baxaysa dhibicdaas.
2. Sharciga Korantada ee Kirchoff (KVL): Wadarta korantada ee wareegga xiran waa inay la mid noqotaa eber.
Su'aal:
Iyada oo la siinayo wareeg leh laba laamood oo is barbar socda. Laanta koowaad waxay leedahay iska caabin 3-ohm ah, laanta labaadna waxay leedahay iska caabin 6-ohm ah, labaduba waxay ku xiran yihiin ilo 18-volt ah. Xisaabi hadda socda ee dhex mara laan kasta iyo wadarta guud ee hadda ku jirta wareegga.
Dood:
Isticmaal Sharciga Ohm ee laan kasta:
Laanta koowaad:
\[ I_1 = \frac{V}{R_1} = \frac{18 \text{ V}}{3 \text{ Ω}} = 6 \text{ A} \]
Laanta labaad:
\[ I_2 = \frac{V}{R_2} = \frac{18 \text{ V}}{6 \text{ Ω}} = 3 \text{ A} \]
Wadarta guud ee hadda waa wadarta hadda ka soo baxda labada laamood:
\[ I_{\text{total}} = I_1 + I_2 = 6 \text{ A} + 3 \text{ A} = 9 \text{ A} \]
Markaa, hadda socda ee dhex mara laan kasta waa 6 amperes iyo 3 amperes, wadarta guud ee hadda socda ee wareegga waa 9 amperes.
