Power o ka pila nuiʻikena. ka mea, ke pono

I ka ninau o mea i ka mana o ka uila he, mea ole ka easiest. Ia e maoli loa pololei, ka mea i loa paʻakikī. Akā, i kēia mea i kekahi o ka walaʻauʻana manaÿo o nā ke kālaikūlohea a me nā 'epekema ka hoʻopaʻi' ana e pili ana i ka uila. I ka maʻamau o ke ola, ua pinepine i ka hoʻohana 'ana i kēia manaʻo.

Me ka hele ana i loko o ka piha clarification, ka mea i ka uilaʻikena a ka mea kona ano maoli, e ike i ka nā keʻano o ka hanaʻana a mākou e hoʻohana i ka analogy o ke kaikuono. Wai kahe mai ka wahi kiʻekiʻe o ka paena ia. No ka uilaʻikena kulana mea like, e kahe ana mai kaʻoi me kekahi ikehu kiʻekiʻe i kekahi wahi malalo Loaʻaʻia. I ka nui o ka Loaʻaʻia like ua kapaia ke anakahi uila, denoted ma ka palapala U, a ua anaia mai ka manawa i loko o huahelu kapa volts.

E hoʻi iā mākou hou i ke kahawai. A hiki i ke kahe ana o ka wai mai ka kiekie o nisin ma ka hoolilo ana o kekahi nui no ia, mai kekahi wahi a hiki i kekahi. I kaʻikena pele i wahi e pili ana i ka mea hookahi: kekahi nui o ka uila ua hoolilo mai kekahi wahi a hiki i kekahi. E ana i kēia kaʻina hana, aia mea he kau pono, ka mea, ua manao like me ka nui o ka uila hala no pa alima manawa ma ke alakaʻi mele pauku. By analogy me ka pūnāwai mea, he nui o ka wai i hele ma ka wae hapa no pa alima manawa. Hōʻikeʻia e ka mea he ikaika hōʻailona aʻu, e ana ia he mea he kūikawā pa alima - amps.

Kēia mau manaÿo - ke anakahi uila a me ka amperage - hana e like me ka papa kuhikuhi ano o ka pila nuiʻikena.

Ka wai e kahe ana mai luna a lalo, hāpai me ia i kekahi ikehu. Kaniak e like me ka mīkini peahi uila huhui, ka mea, e hoʻihoʻi mai i ke kuapo o ka hope, a hana i kekahi hana. Like me, ka uila he hiki ke hana i ka hana. Keia hana ua hana i loko o kekahi lua, a me ka mea i ka mana o ka pila nuiʻikena. Ua i ia ma ka palapala P, a me ka mea, ua anaia mai ka manawa i loko o watts.

Ka hana i hana 'ia me ka wai i ka haule ana, ka manao ana o kona dala e haule ana i loko o ka mīkini peahi uila kōmi' ana, a me i ka mea hina kiekie. Ua nui ka wai i ka mea i oi aku ke kiekie mai ka i ka mea hina, i ka oi hana ua hana. Like me, ka mea kiʻekiʻe i ke anakahi uila (ke koena unuhi i loko o ka wai kiʻekiʻe) a me ka amperage (a laila, ka wai), me ka nui o ka hana i hana, a nolaila, i ka mana o ka pila nuiʻikena.

Inā 'oe e ho'āʻo i ka formalize i kēia manaʻo, a laila, a pau ke ke kaheaia ma ka mea haʻilula:

P = Owau no ia U,

kahi: P - mana o ka uila pono i loko o watts;

I - kala pono i loko o amperes;

U - anakahi uila, ma volts.

'O kēia ke kumu o haʻilula ana a oe ke hoʻoholo i ka' auhau o ka pila nuiʻikena.

Eia naʻe, ma kahi e ka uilaʻikena lua i pele i ole ma Hōʻuluʻulu hua'ōlelo, akā, i loko o ka makemake i puhi ai i i kā lākou mau 'ano. Ma 'ana, ke alakaʻi mele o ka ia'ku, a me ke anakahi uila U a me kaʻikena au i ua hoʻopili i loko o ke kaulahao ma ka DC he kahe ana ma ia'ku Ohm ka kānāwai. No laila, i ka mana huakai kaapuni DC i kohoʻia e hoike i ka olelo o ka ia'ku, a, e lawe i loko, no na ano o ke kaula i loko o ka olelo no ka mana o ke Ohm ka kānāwai pono a me ka anakahi uila pili.

Aie i ka mea i ka huakai kaapuni i ka ia'ku,ʻaʻole pau i ka ikehu hoʻohana i ka hana maikaʻi kēia hana. Part no ka mea, ua nalowale i ka hooholo ana o ke kaula. No laila, ka mea e hoʻopā ai ka ikehu, a laila mana kahi ikehu e kela aku kona nui ma mua o ka mana e pono ai e hana i kekahi hana. Ia e halihaliia oia iwaho no laila,-kapaʻia ka ikehu kaulike - nona iho haawiia kumu pono e like me ka mana i hoopauia e ka haawe ana a me ka mana lilo ma ke alakaʻi mele o ka uilaʻikena.

Kahi o ke kiʻi i ka hōʻuluʻulu manaʻo o ka mea i ka mana o ka uila pono e like me ka mea i ho'ākāka 'ua, ma i hilinaʻi nui.
