He aha ka ka electromotive ikaika

Ma kēia 'atikala e kamaʻilio pū mākou e pili ana i ka mea i ka electromotive ikaika mana kumu a me ka mea o kona pilina me nā mea kiko'î o ka huakai kaapuni. Pono e hoailona oukou, hoʻowahāwahā i ka mea i loko o maʻamau o ke ola mākou i ana hoʻohana pou nā mīkini home, he nui kānāwai i ua loko empirically a me ia no ka haawi. 'O kēia kekahi o nā kumu no excessive ka manaʻo pohihihi wehewehena i. Eia naʻe,ʻo ka electromotive ikaika, i kumu o ka uila 'enekinia, ua hoomalamalamaia mai i loko o ia i ke ala ana i ke kanaka i mea ole kama'āina me ka uila, e ike i kekahi mea he pilikia. E wehewehe i ka pukana me ke kōkua o akaka hua'ōlelo kēlā, a me nā examples.

Directional neʻeʻana o ka papa mai (particles) i loko o ke alakaʻi mele ua kapaia ka "uilaʻikena". E like me ko oukou ike ana, i nā mea a pau o ko mākou mea honua haku o nā'ātoma. No ka pono o ka mōakaaka, ua hiki kuhi i kēlā me kēia'Ātoma ua poe i loko o ka palapala hoemi miliona o ka manawa o ke kumu hoʻohālike o ka poe lń: ma ka waena konu o ka Kora naʻEsau, a ma kekahi mau mamao mai ia i loko o hoʻopoepoe orbits o na electrons revolve.

Ma kekahi mawaho hopena i loko o ke alakaʻi mele ho okumu i ka paʻa kaapuni, electromotive ikaika ua ua loaʻa, a laila mea he pila nuiʻikena. Hopena "kikeke mai" valence electrons mai lākou orbits i loko o nā'ātoma no laila, hua mai la noa electrons a me ka ikaika kauoha Ion.

Electromotive ikaika mea pono i ka "poe" 'āhewa' ana, e malama i neʻe ma ke alakaʻi mele, a me ka huakai kaapuni hehee wale i loko o ka kekahi ao ao. Ole ia, i ka he aneane koke pio. Hoʻokaʻina 'ia nā mea o ka electromotive ikaika mai, e ae i ka hoʻohālike o ka uila a me ka wai. Hike paipu pauku - keia alakaʻi mele. Kona mau aoao e hele aku i loko o ka wai kino. Like loa me ka wai pae ma na Reservoir e kau like, a he mea ole haiahū kūmau, i ka wai i loko o ka ohe ka wahi.

ʻae nō hoʻi, e kiʻi iā ia, e neʻe i ka ekolu aoao: e ho okumu i kekahi kiekie oko ao (pāʻewaʻewa 'ole i ka huina o ka loli ma ka Reservoir) a me ka poe ikaika no lakou EII ni. An nui wahi: ina ua kamailio e pili ana vertical kulu (Loaʻaʻia koena unuhi), e hoʻi i ka stress. No ka EMF ia neʻe "puʻe wale" no ka mea, ma waho koa me ka hoohuoi ana, nonpotential.

I kekahi kumu o ka uilaʻikena i EMF - ka ia mana e kākoʻo i ka neʻeʻana o ka papa (particles) (i loko o ke kēia analogy koa ne e ka wai). Ana i loko o volts. Ka inoa e'ōlelo no iho: EMF characterizes ka hana pili i kekahi mahele o ke kaula o ka mawaho koa e hana i ka pohupani hale o kela a me keia pa alima uku ole mai kekahi laau a hiki i kekahi (ma waena o maʻi). He heluna hapauuku like me ka lākiō o ka hana o ka mawaho koa pili ana i ka waiwai o ka hoʻoneʻe malama.

Kahiko o ka'āina Pono emf kumu hiki ke loko mai o ke kānāwai o ka mālama o ka ikaika, a me ka waiwai o ke alakaʻi mele. I ka paʻa kaapuni hana kahua ma luna o ka neʻeʻana o ka hewa ana i hoopiia mea Aʻohe. Naʻe, ke alakaʻi mele ua enaena (a me ka ikaika i ka nuiʻikena hele ma ia no pa alima manawa). Ka Hopena: ka huakai kaapuni e e ike i ka like ana o ka mawaho ikehu. I aku la o waho koa - keiaʻume mākenēki kahua nā mīkini uila, ka pīhoihoi electrons noke; ka ikaika o Nine Inch reactions ma iuo aaoa?.

Ke electromotive ikaika o ka hoʻokomo i mua malama experimentally i ka makahiki 1831 ma ka physicist Faraday. He loaʻa i ke alakaʻi mele-permeate laina pinepine 'alternatingʻume mākenēki ke kahua, he pila nuiʻikena. Waiū e kekahi mahinaʻai hoike o ka pahale mawaho electrons i loko o nā nā'ātoma o ka ikehu nalowale ia ia, ma o na la ia e uhai aku, a hoʻomaka i ka hoʻoneʻe (ʻikena lua i pele). O ka holo ana, i ka pololei neʻeʻana o nā (particles) hakuʻole (hiki ole hoomanao i ka relativity o ka pou axioms). Kaupalena naʻe, he mea ka e loaa hou mai no (particles) ma waena o ka mea kokoke i nā'ātoma.

Hoʻomohalaʻia e ka electromotive ikaika - ia mea he na ano o kekahi mana kumu.
