Zinthu Zotsutsana ndi Mndandanda
Ngati zotsutsana ndi magetsi zalumikizidwa monga momwe zasonyezedwera pachithunzi pamwambapa, zimalumikizidwa motsatizana. Zotsutsana ndi magetsi zomwe zikukambidwazi zitha kukhala zigawo za resistor, nyali, kapena zida zina zamagetsi zotetezera kutentha.
Chaji yamagetsi (Q) ndi yokhazikika kotero kuti mphamvu yamagetsi ikuyenda kudzera mu kukana 1 (R)1) = chaji yamagetsi ikuyenda kudzera mu kukana 2 (R)2) = chaji yamagetsi ikuyenda kudzera mu kukana 3 (R)3). Mphamvu yamagetsi (I) ndi mphamvu yamagetsi yomwe imayenda mkati mwa nthawi inayake (I = Q/t), motero mphamvu yamagetsi yomwe imadutsa mu kukana 1 (I1) = magetsi amagetsi omwe amadutsa mu kukana 2 (I2) = magetsi amagetsi omwe amadutsa mu kukana 3 (I3Mwa masamu, mphamvu yonse yamagetsi (I) = I1 = Ine2 = Ine3.
M'malo mwake magetsi amagetsi (V) imachepa pamene mphamvu yamagetsi ikuyenda kudzera mu resistance iliyonse. Voltage yamagetsi, yomwe imatchedwanso kusiyana kwa mphamvu yamagetsi, ndi mphamvu zamagetsi pa unit iliyonse ya mphamvu yamagetsi. Voltage imachepa chifukwa mphamvu yamagetsi imagwiritsidwa ntchito pa kukana kulikonse kwamagetsi. Chifukwa chake voteji yonse yamagetsi (V) ndi yofanana ndi kuchuluka kwa mavoteji amagetsi pa kukana kulikonse. Mwa masamu, voteji yonse yamagetsi (V) = V1 +V2 +V3V = IR kotero equation yonse yamagetsi ndi V = IR1 + IR2 + IR3Mphamvu yamagetsi yomwe ikuyenda kudzera mu resistor iliyonse ili ndi mtengo womwewo kotero equation iyi imasintha kukhala V = I (R1 +R2 +R3).
Kutengera ndi equation yomwe ili pamwambapa, zitha kutsimikiziridwa kuti kukana konse kwamagetsi (R) kapena kukana kofanana kwa kukana kwamagetsi kolumikizidwa motsatizana ndi kofanana ndi kuchuluka kwa kukana kulikonse kwamagetsi, mwa masamu R = R1 +R2 +R3Ngati pali zotsutsana ziwiri zokha zomwe zalumikizidwa motsatizana, ndiye kuti mtengo wa chotsutsa chosinthira (R) = R1 +R2Ngati pali zotsutsana zinayi zolumikizidwa motsatizana ndiye kuti mtengo wa chotsutsa chosinthira (R) = R1 +R2 +R3 +R4Mofananamo, ngati pali zotsutsa zisanu kapena kuposerapo zolumikizidwa motsatizana.
Chitsanzo cha vuto la resistor ya mndandanda:
1. Kupatsidwa R1 = 2 Ω, R2 = 3 Ω ndi R3 = 4 Ω. Ma resistors atatu alumikizidwa motsatizana. Kodi mtengo wa resistor wolowa m'malo ndi wotani? (Ω = Ohm).
Zokambirana
R = R1 +R2 +R3 = 2 + 3 + 4 = 9 Ω.
Zotsatirazi zikusonyeza kuti mtengo wotsutsa wolowa m'malo ndi waukulu kuposa mtengo wotsutsa wa chotsutsa chilichonse cholumikizidwa motsatizana.
2. Zotsutsa ziwiri R1 = 50 Ω ndi R2 = 50 Ω yolumikizidwa motsatizana ndipo yolumikizidwa ku batri ya 12 Volt. Dziwani (a) kukana kofanana (b) mphamvu yamagetsi yomwe imadutsa mu resistor iliyonse.
Zokambirana
(a) R = R1 +R2 = 50 Ω + 50 Ω = 100 Ω.
(b) I = V / R = 12 Volts / 100 Ω = 0,12 Ampere
