Nkhani yokhudza khodi ya mtundu wa Resistor
Choletsa ndi chimodzi mwa zigawo za magetsi zomwe zimagwira ntchito yowongolera kuchuluka kwa mafunde amagetsi. Kawirikawiri, pali mitundu iwiri ya zoletsa, zomwe ndi zoletsa waya ndi zoletsa kaboni. Zoletsa waya nthawi zambiri zimagwiritsidwa ntchito mu labotale, zopangidwa ndi kukulunga waya wopyapyala pamwamba pa chubu choteteza. Zoletsa kaboni nthawi zambiri zimagwiritsidwa ntchito m'mabwalo amagetsi, ozungulira, ndipo ali ndi mawaya mbali zonse ziwiri. Mtengo wa kukana kaboni umafotokozedwa mu mtundu ndipo umawonetsedwa pamwamba pa choletsa.
Mtengo wotsutsa wa resistor ukhoza kudziwika potanthauzira mtundu wa resistor code. Kuti mumvetse izi, choyamba yang'anani tebulo lotsatira, kenako phunzirani chitsanzo cha vutoli kuti mudziwe mtengo wotsutsa resistor.
Chitsanzo cha vuto 1:
Mtengo wa kukana kwa resistor pachithunzichi ndi ...
yankho;
Mitundu iwiri yoyamba ikuyimira manambala awiri oyamba a mtengo wotsutsa, mtundu wachitatu ukuyimira mphamvu yakhumi yomwe imagwiritsidwa ntchito kuchulukitsa, ndipo mtundu wachinayi ukuyimira kulolerana kwa kupotoka.
Mtundu woyamba = wofiira = 2
Mtundu wachiwiri = lalanje = 3
Mtundu wachitatu = bulauni = 101 = 10
Mtundu wachinayi = golide = 5%
Mtengo wa resistor ndi 230 Ω yokhala ndi kupotoka kwa 5% x 230 Ω = 11.5 Ω. Ngati kutentha kwasintha, kukana kocheperako ndi 230 11 – 11.5 Ω = 218.5 Ω ndipo kukana kwakukulu ndi 230 Ω + 11.5 Ω = 241.5 Ω.
Chitsanzo cha vuto 2:
Kodi mtengo wa resistor resistor womwe uli pachithunzichi ndi wotani?
yankho;
Mtundu woyamba = bulauni = 1
Mtundu wachiwiri = wakuda = 0
Mtundu wachitatu = buluu = 10 6 = 1000,000
Mtundu wachinayi = golide = 5%
Mtengo wa resistor ndi 10,000,000 ,000 ndi kupotoka kwa 5% x 10,000,000 Ω = 500,000 Ω. Ngati kutentha kwasintha, chopinga chochepa ndi 10,000,000 500 – 500,000 Ω = 9,500,000 Ω ndipo chopinga chachikulu ndi 10,000,000 Ω + 500,000 Ω = 10,500,000 Ω.
