Choletsa ndi gawo la magetsi lomwe limagwira ntchito yowongolera kukula kwa mphamvu yamagetsi. magetsiMa resistors omwe amagwiritsidwa ntchito m'mabwalo amagetsi nthawi zambiri amakhala ozungulira ndipo waya uli mbali zonse ziwiri. Kukana kwa resistor kumawonetsedwa ndi mtundu wa code ndipo kumawonetsedwa pamwamba pa resistor.
Kufunika kwa kukana kwa resistor kumadziwika potanthauzira khodi ya mtundu wa resistorKuti mumvetse izi, choyamba onani tebulo lotsatirali, kenako phunzirani chitsanzo cha vuto lodziwa kukana kwa resistor.
Chitsanzo cha funso 1:
Mtengo wotsutsa wa resistor pachithunzi chomwe chili pambali ndi...
Zokambirana
Mitundu iwiri yoyamba ikuyimira manambala awiri oyamba a mtengo wotsutsa, mtundu wachitatu ukuyimira mphamvu ya khumi yomwe imagwiritsidwa ntchito pochulukitsa ndipo mtundu wachinayi ukuyimira kulekerera kwa kupotoka.
Mtundu woyamba = wofiira = 2
Mtundu wachiwiri = lalanje = 3
Mtundu wachitatu = bulauni = 101 = 10
Mtundu wachinayi = golide = 5%
Mtengo wotsutsa wa resistor ndi 230 Ω ndi kupotoka kwa 5% x 230 Ω = 11,5 Ω. Ngati kutentha kwasintha, kukana kocheperako ndi 230 Ω – 11,5 Ω = 218,5 Ω ndipo kukana kwakukulu ndi 230 Ω + 11,5 Ω = 241,5 Ω
Chitsanzo cha funso 2:
Kodi mphamvu ya resistor pachithunzi chomwe chili pambali ndi yotani?
Zokambirana
Mtundu woyamba = bulauni = 1
Mtundu wachiwiri = wakuda = 0
Mtundu wachitatu = buluu = 106 = 1000.000
Mtundu wachinayi = golide = 5%
Mtengo wotsutsa wa resistor ndi 10.000.000 Ω ndi kupotoka kwa 5% x 10.000.000 Ω = 500.000 Ω. Ngati kutentha kwasintha ndiye kuti kukana kochepa ndi 10.000.000 Ω – 500.000 Ω = 9.500.000 Ω ndipo kukana kwakukulu ndi 10.000.000 Ω + 500.000 Ω = 10.500.000 Ω.
