He aha anakahi uila

A me ka manaʻo o "anakahi uila" a pau o mākou i ka maka kokoke i kela lā, no ka mea, ua i kaupalena 'wale i nā mīkini home o ka wahi o ka pono. Keia uwila i ka ua, a me nā hunaahi ma luna o ka ea waihona meli a me nā kapa o kemikala olona, a pela aku.

Maloo ana KU¯ ōlelo hoʻolako i nā kēia ka wehewehena o ka kŰia: anakahi uila - mea he physical nui e hoike ana i ka huina i hana ma kaʻoihana ma 1 C (coulomb) hana. Lei'ā'ī, i ka huli, Hōʻike i ka nui o ka uku ole o ka nalowale lawelawe nā no 1 kekona me ka papa o ka 1 A.

Ua mea no hoi ana i kekahi ho'ākāka 'ana, e like me a ke anakahi uila o ka lākiō o ka hana i hanaʻia e ka uila ke kahua ma ka neʻeʻana o ka hoao ana (kaʻimi) e mālama ai ma waena o nā kumu, a hiki i ka laulā waiwai o kēiaʻoihana. Ma keia hihia ka mea, ua ea ae ka hana i kaʻoihana hoololiia ana, aole ia he aha ka mea i ka Loaʻaʻia likeʻole (anakahi uila 'aʻole e hoʻololi), a me ke ala o ka neʻe hiki ke AOON. Ma ka haʻilula ua kākau i kēia ho'ākāka 'ana penei:

U = A / Q,

kahi U - anakahi uila, A - hana, Q - kauoha.

E hoomanao i ka mea a ka mea i ana ai i anakahi uila,ʻaʻohe mea'ē aʻe e pono ma ka naauao, no ka mea, kōkua mea mau ma ka lima, no ka mea a pau i kaʻikena kumu Hōʻike anakahi uila waiwai a me kona Ana: ia mea nui, e nānā i kekahi o na pu ki. Unit - V (B, V).

Nā hua'ōlelo "anakahi uila" no ka DC, a AC wahi i puhi ai iʻokoʻa. Ma alternating papa, wehewehe aku ma ka papa'āweʻaweʻa kemika sinusoid hooholo ma ka 'Aʻohe wahi, ua hoʻohana' ia no ka mea i ka ho omaulia mea ole instantaneous, a me RMS waiwai. He mea hiki i ke aloha i ka mea i kona 'oihana me kaʻeleu laina e haawe hoʻopili like heluna hapauuku i ka DC anakahi uila.

Ka poʻe hoʻi i ka manawa e hana me ekolu-pae Hawaii, oiaio hukihuki lakou i ka noonoo ana i ka malihini e komo i loko o ka palapala holo'āina'ē ano e. Aia, ma ka hahau ana i ka 'mau voltages e like me 220/380 V. Aole mea ole typo ma laila, ka mea, i ka ipu mea hiki ke hana i nā kekahi pae'ōnaehana loina. Where 'Aʻole i ka mea ulana pukapuka, 380 ke lawe 220? Ua huli mai, i ke anakahi uila hiki e kekahi pae paha laina, ke kaumaha ma muli o ka huahelu hana. Pae ua nānā 'ia e ana i ka likeʻole ma waena o kēlā me kēia pae a me ka'ākilikai nā alakaʻi mele, a me ka laina - ma waena o ka pae conductors. Ma ka ai pili aku i ka haawe kaapuni i loko o ka triangle, kekahi ke loaa i ka laina a me ka ewaewa ole pae voltages, a me na wahi i puhi ai "hoku" pae He 1,73 manawa emi laina.

voltmeter - he kūikawā mea ua hoʻohana 'ia ana anakahi uila. Kona papa kuhikuhiE hiʻona - o ka pono, e hoʻohui tokosnimayuschih probes ma ka haawe. High maloko ia'ku 'aʻole i hoʻolauna ei shunting. I mea no ke aha la, no ka laʻana, i wahi lulu ana i ia i ka pololei pilina i ka mākeke (like ammeter ka loaʻa o ke kaapuni).

Akā, e yoa? Iiai haʻilula kula a me na hoike, i mea ka "uila anakahi uila", ma ka alodio kanaka 'ōlelo. Ke'ī mai, i ke koena unuhi o ka uku ole (Loaʻaʻia) ma waena o nā ākeʻakeʻa kumu nui o ke alakaʻi mele a me ka pila kahua. Kumu ka mea e hookomo ana i ke alakaʻi mele o electrons (ka mīkini hana wāwahie, he o na pu ki) paha ke i kekahiʻaoʻao o ko lākou waiwai nui, a me ka mea 'ē aʻe - io. Alaila, o kekahi o ka waiwai o ka hewa ana i hoopiiaʻokoʻa. Ua, ke kala e hoʻohui i kēia mau mea nui o kekahi e mālama nei meakino, i hoʻomaka ai a me ka uila pono - o ka neʻeʻana o ka papa (particles), mālama i ke neutralize keia koena unuhi. Ma nā hua'ōlelo, ka he kuhi keʻano wehena nā'ātoma i ka paa ana, o na kanaka haunaeleʻume mākenēki mahinaʻai o ka mīkini hana wāwahie. Hoʻopilikia hiki nei me ka pono ina ka ia'ku ma waena o nā kumu i mea nui. Kēia wehewehe i ka mea i na iuo aaoa? I ole kama'āina "kaua i kaʻikena."
