Ƙarfin wutar lantarki yana kwatanta ikon daLED fitiladon fitar da ikon aiki. Power shine ma'auni na yawan isar da kuzari, kuma a cikin da'irori na DC samfurin ƙarfin lantarki ne na V da na yanzu A. A cikin tsarin AC, ya fi rikitarwa: wasu AC halin yanzu suna kewayawa a cikin kaya, wanda ake kira reactance current ko Harmonic halin yanzu, wanda ke sa ikon bayyane (voltage Volt ta Amps na yanzu) ya fi ƙarfin gaske. Bambance-bambancen da ke tsakanin iko na zahiri da ainihin iko yana kaiwa ga ma'aunin wutar lantarki, kuma ma'aunin wutar lantarki yana daidai da rabo na ainihin iko zuwa bayyanannen iko. Don haka ainihin ikon da ke cikin tsarin AC yana daidai da ƙarfin dogaro da sauƙaƙan ƙarfin wutar lantarki.
Wato: factor factor = ainihin iko / bayyanannen iko. Iyakar wutar lantarki na nauyin layi kamar wutar lantarki da kwan fitila mai haske shine 1. Bambanci tsakanin ainihin wutar lantarki da kuma bayyana ikon kayan aiki da yawa yana da ƙananan ƙananan kuma ba shi da kyau, yayin da bambanci tsakanin kayan aiki mai mahimmanci kamar fitilu yana da girma da mahimmanci. .

Ikon aiki: samfurin wutar lantarki na AC da AC halin yanzu. Tare da dabara kamar: S=UI. Inda S aka ƙididdige ƙarfin fitarwa a cikin VA (volt-ampere); U ana kimanta ƙarfin fitarwa a cikin V, kamar 220V, 380V, da sauransu; An ƙididdige ni a halin yanzu a cikin A. Ƙarfin da ke bayyana ya ƙunshi sassa biyu: ƙarfin aiki (P) da ƙarfin amsawa (Q). Ikon aiki yana nufin ɓangaren aikin da aka yi kai tsaye. Misali, hasken wuta, jujjuyawar mota, da'ira na aiki. Domin wannan iko ya zama zafi, mutane za su iya jin su kai tsaye, don haka wasu mutane suna da hasashe, wato ikon aiki a matsayin ikon bayyananne, wanda ya san ikon aiki wani bangare ne kawai na
Ƙarfin bayyane, tare da dabara: P = Scos θ = UIcosθ = UIF. Inda P shine ikon aiki a cikin W (watts); F=cos θ ana kiransa da wutar lantarki, kuma θ shine bambancin lokaci na igiyoyin wutar lantarki daban-daban a wani nauyi mara nauyi. Ƙarfin mai aiki shine ɓangaren ikon da aka adana a cikin kewaye amma ba a yi aiki kai tsaye ba, wanda aka bayyana ta hanyar dabara: Q = Ssin θ = UIsinθ. Inda Q shine ƙarfin amsawa a cikin var (rashi).
DominLed fitulun kaida duk sauran na'urorin lantarki da ke aiki akan wutar lantarki na DC, ba shi yiwuwa a yi aiki ba tare da wuta ba.
