Ƙarfin wutar lantarki mai tsaka-tsaki ya kasu kashi zuwa ƙarfin aiki, ƙarfin amsawa, ƙarfin wuta da kuma bayyanannen iko.

1. Ƙarfin wutar lantarki na tsaka-tsakin wutar lantarki yana wakiltar adadin wutar lantarki ta hanyar wutar lantarki a cikin lokaci guda (1 s). Ƙarfin aiki koyaushe yana ƙasa da (aƙalla daidai da) ƙarfin bayyane. Misali, idan wutar lantarki a fadin inductor shine 50V kuma na yanzu yana gudana ta cikinsa shine 4000A, ikon da yake bayyane shine 200kV A, kuma ƙarfin aiki wanda na’urar aiki da inductor ke ɗauka shine 30 kW (factor factor na 0.15), ko 80kW. (matsalar wutar lantarki shine 0.4). Yana da ikon cinye ta inductor da workpiece don ainihin dumama. Wurin wutar lantarki mai aiki na tanderun mitar matsakaici shine Kw

2. The reactive ikon na matsakaici mita tanderu yana nufin girman da electromagnetic ikon lokacin da wutar lantarki da kuma Magnetic makamashi suna musayar a cikin oscillating tanki kewaye hada da matsakaici mita makera inductor da capacitor banki a induction dumama na’urar na tsakiyar mitar tanderu. Wannan yana nufin cewa wani yanki na wutar lantarki da aka ba da wutar lantarki za a mayar da shi zuwa wutar lantarki ta hanyar da’irar oscillation. Nau’in ikon amsawa shine kvar, kuma ƙimarsa daidai yake da bambancin murabba’i tsakanin ikon bayyane da ikon aiki sannan kuma mai murabba’i, kuma sashin wutar lantarki na matsakaicin mitar shine Kvar.

3. Matsakaicin wutar lantarki na tanderun mitar matsakaita shine rabon ƙarfin aiki zuwa ƙarfin bayyane (kW/kV.A), kuma ƙimarsa yana nuna adadin ƙarfin da yake gani yana ɗauka ta hanyar aiki mai aiki a cikin zagaye ɗaya na oscillation na lantarki.

4. A wata ma’ana, alamar wutar lantarki ta wutar lantarki mai tsaka-tsaki ita ce jimlar ƙarfin aiki P da ƙarfin amsawa Q, samfurin ƙarfin lantarki da na yanzu a cikin kewaye, kuma naúrar shine kV.A. Misali, idan farkon wutar lantarki na taransfoma shine 800 V kuma na yanzu shine 500 A, ƙarfin da yake gani yana daidai da 400kVA. A cikin da’irar DC, ikon da ke bayyane yana daidai da ƙarfin aiki, kuma “bayyani” ba shi da ma’ana a wannan lokacin. A cikin da’irar AC, musamman a cikin da’irar tanki na induction dumama kayan aiki, lokacin da ake ci gaba da musayar makamashin lantarki da ƙarfin maganadisu, wani yanki na makamashin ne kawai na’urar aikin ke ɗauka, kamar a cikin da’irar motar AC 50Hz, kawai wani ɓangare na makamashi yana sha. Wurin wutar lantarki na fili na tanderun mitar matsakaici shine Kvar.

A taƙaice, an bambanta ra’ayin wutar lantarki na tanderun mitar matsakaici. Lokacin magana game da ikon wutar lantarki na tsaka-tsaki, ya kamata a bambanta ikon wutar lantarki. A al’ada, ƙarfin dumama na tanderun mitar matsakaici yana nufin ƙarfin aiki na tanderun mitar matsakaici.
