Iska-caabintu waa qayb ka mid ah wareegga korantada oo xakameysa xaddiga qulqulka korantada . Iska-caabinta loo isticmaalo wareegyada elektaroonigga ah badanaa waa qaab dhululubo leh oo leh silig labada darafba. Qiimaha iska-caabinta ee iska-caabinta waxaa lagu tilmaamayaa kood midab leh waxaana lagu soo bandhigayaa dusha sare ee iska-caabinta.
Qiimaha iska caabbinta ee iska caabbinta waxaa lagu go'aamin karaa iyadoo la fasirayo lambarka midabka iska caabbinta . Si aad tan u fahamto, marka hore baar jadwalka soo socda, ka dibna baro dhibaatada tusaalaha ah ee lagu go'aaminayo qiimaha iska caabbinta ee iska caabbinta.
Tusaale ahaan su'aal 1aad:
Qiimaha iska caabbinta ee iska caabbinta sawirka dhinaca waa...
Dood
Labada midab ee ugu horreeya waxay matalaan labada lambar ee ugu horreeya ee qiimaha iska caabbinta, midabka saddexaad wuxuu matalaa awoodda tobanka loo isticmaalo isku dhufashada iyo midabka afraad wuxuu matalaa dulqaadka leexashada.
Midabka koowaad = casaan = 2
Midabka labaad = oranji = 3
Midabka saddexaad = bunni = 101 = 10
Midabka afraad = dahab = 5%
Qiimaha iska caabbinta ee iska caabbinta waa 230 Ω oo leh leexasho ah 5% x 230 Ω = 11,5 Ω. Haddii uu jiro isbeddel heerkulka ah, iska caabbinta ugu yar waa 230 Ω – 11,5 Ω = 218,5 Ω iska caabbinta ugu badanna waa 230 Ω + 11,5 Ω = 241,5 Ω.
Tusaale ahaan su'aal 2aad:
Waa maxay qiimaha iska caabbinta ee iska caabbinta ee sawirka dhinaca?
Dood
Midabka koowaad = bunni = 1
Midabka labaad = madow = 0
Midabka saddexaad = buluug = 106 = 1000.000
Midabka afraad = dahab = 5%
Qiimaha iska caabbinta ee iska caabbinta waa 10.000.000 Ω oo leh leexasho ah 5% x 10.000.000 Ω = 500.000 Ω. Haddii uu jiro isbeddel heerkulka ah markaa iska caabbinta ugu yar waa 10.000.000 Ω – 500.000 Ω = 9.500.000 Ω iska caabbinta ugu badanna waa 10.000.000 Ω + 500.000 Ω = 10.500.000 Ω.
