Ka hopena o ka mana ma nā poʻo alakaʻi alakaʻi

ʻO ka mea nui ka mana nui o nā kukui i alakaʻiʻia,ʻaʻohe meaʻO nā kukui i alakaʻiʻiaa iʻole nā ​​kukui i alakaʻiʻia. No laila e hoʻomaopopo houʻia i ka mea nui o ka mana.

1, mana
Hōʻike ka mana mana i ka hiki i kaKauhi o ke poolae hoʻokau i ka mana ikaika. ʻO ka mana he ana o ka hoʻoiliʻana o ka ikehu, a ma DC Circuitsʻo ia ka huahana o kēia manawa,ʻo ia ka mea e like me ka mana o A. ʻO kaʻokoʻa ma waena o ka mana o ka mana a me ka mana maoli i alakaʻi i ka mana o ka mana, a he like ka mana o ka mana o ka mana maoli i ka mana maoli. No lailaʻo ka mana maoli i ka'ōnaehana AC e like me ka mana hilinaʻi i nā manawa kūpono i ka mana o ka mana.
ʻO ia:ʻO ka mana mana = mana maoli / hana maikaʻi. ʻO ka mana wale nō ka mana o ka laina laina e like me ka mea e pili ana i ka mea hoʻohana uila a me nāʻano likeʻole ma waena o nā lako hana he nui a he nui loa.

2, he mana kūpono
Mana ikaika:ʻO ka huahana o ka hua'ōlelo AC a AC i kēia manawa. Me ka formula e like me: s = ui. Kahi i kauʻia ai ka mana o ka mana i loko o va (volt-ampere); U ua heluʻia i ka voltage intutuating ma v, e like me 220v, 380v, etc .; Ua heluʻia wau i nā mea i kēia manawa ma A.ʻO ka mana o nā mana i loaʻa iʻelua mau'āpana: ka mana ikaika (p) a me ka mana hou (q). ʻO ka mana ikaika e pili ana i ka'āpana o ka hana i hana pololei. No ka laʻana, ke kukui, ka uila, ke kaʻa uila, keʻano uila uila uila. I ka mea ua wela kēia mana, hiki ke maopopo i nā kānaka, no laila, he poni nui kekahi i ka mana hana,ʻo ia ke mana mana
ʻO ka mana kūpono, me ka formula: p = scos θ = uicoss = Uif. Kahi o ka mana ikaika i W (Wallts); F = Ua kāheaʻiaʻo Cos θ o ka mana o ka mana, aʻo θ kaʻokoʻa o nāʻano likeʻole o nāʻano likeʻole i kahi ukana nonlinear. ʻO ka mana reactive ka hapa o ka mana i mālamaʻia i loko o ka carcuit akāʻaʻole i hana pololeiʻia, i hanaʻia e ka forcula: q = ssin θ = uisiny. Kahi qʻo ia ka mana reactive ma var (nele).

No kaAlakaʻi i nā poʻoa me nā mea āpau'ē aʻe āpau e hana ai ma DC VILtage,ʻaʻole hiki ke hana me ka manaʻole.
