AC mana. DC, a ACʻikena

I kekahi kanaka ka mea i wae mai ai, e hana me ka uila 'enekinia, me kaʻoihana, e ike loa ma laila mea i na kumu o ka lako, e like me kā lākou mau hiʻona a me ka oko ao. I ka mea, aohe mea huikau, e like me mākou e hōʻike i loko o kēia 'atikala.

He mea eha e noonoo ai i na pehea e nana nalo o kēia au nei, mai kona uila ikehu a me nā nā mīkini home. Paha, kanaka nō e hana mahu kiko'ī a me Muscle ka mana o na holoholona, a no ko lakou mau hoahanau. Kekahi hiki ole ke olelo pono i mua ike i ka pou ikehu: no ka laʻana, spinners i kahiko Suria hoʻohana i ka Amber waiwai magnetized (hoʻouila), Aristotle ho'āʻo e makaikai i na nā papaha o ka uila Ray, akā, i ka mea e pili ana i ka pilikia o ka uila, uaʻikeʻia mai ke kinohi o ka honua (ʻaʻohe mea kupanaha kekahi kanaka hoomana aku ia ia).

An uila papa mea o nāʻano likeʻole - AC a me DC. Kēia koena unuhi mea ku pono i kona hoʻomākaukau hana. Alaila, o ka AC mana kumu 'oi aku ka pono o ka' ano mua, a me ka ikaika - lua. Ma ke ala, 'aneʻi i ka papa i loko o "mua - kekona" conditionally. I ka uila 'enekinia, ua hoʻohana' ia e like me ka mana lako AC a me DC. E mākou keia iloko o kekahi kumumanaʻo.

Kekahi uila au i ho i ka holo ana o na mea i papa (particles) kuhikuhi ma ka lawelawe mea o ka electromotive ikaika EMF. Mawaho hana e like me kekahi mau electrons ma ka pā orbits o nā'ātoma, oi ikehu lawa e lanakila i ka attraction o ka nucleus. E like me ka hopena, eia noa malama nā moku halihali mokulele - electrons a me ka Ion. E like me ke kānāwai o ka mālama o ka ikehu, he kaʻina o maoli recombination (particles), mai na nā'ātoma a puni ma ka puka olu oia i mea hoʻopuka. Ole mawaho manaʻo 'ole o ka mea ua hoihoi hou ia. Naʻe, ina ke alakaʻi mele ua pili i kekahi kumu o ka electromotive ikaika, ka mea ua loaʻa ke kahua e kuhikuhi ia ia i ka recombination ma ke ala e hiki aku akau - he pila nuiʻikena. AC nae ho mīkini hana wāwahie emf maʻi lele kona kohoʻia loli aʻe ma ke kamepiula nana e hoole. Nolaila i ka inoa "ee iaaanu aey". AC mana na lako i loko o ka hapanui hihia poe ma ka hoʻomakaʻia nona iho - nā mīkini uila ma ke kālā no ka mana kanu mea ulu e like alternatingʻikena. Ka mea, ua oi ike loea ma ka hana a me ka oluolu, e malama, ma mua o ka ÿauhau kumu hoʻohālike no DC. pinepine ke kiʻikuhi i AC mana kumu i hoʻokohu 'ia e kekahi hoa kanaka me ka hawewe i loko o. Kēia nalu - he symbolic kiʻi o ka sine nalu.

AC kahi produces ana o na (particles) ole wale me ka hoʻololi kauoha, akā, he "lana" poe ikaika no lakou waiwai. Oāwa sinusoid Hōʻike i kekahi manawa ka waiwai hele ma 'Aʻohe.

Ma ka loa okoa rula ma muli DC mana. Ka mea hana i kekahi alakaʻi mele a eia i uila kahua ma ke ala e hiki aku o ka ho okumu i directional neʻe ka huna kauoha. Ua Ua noʻonoʻo i kaʻikena kahe ana mai ka maikaʻi a hiki i ka hopena maikaʻi hui '(mai ka maikaʻi i ka io). I aku o ka lanakila, na electrons neʻe i loko o ke ku pono ana i ala e hiki aku - mai ka hua i ka hua hoʻohui. Mai ke kauoha o ka hookahi huina'ine ka io, i ka maʻi me ka "hua" hoailona Hōʻike i ka oi o ka (particles) (ma keia hope aku i ka huina kauoha). Ma muli o ka nui, e hoike ana i ka ae oppositely papa (particles),ʻo kekahi i kekahi, ia mea,ʻaʻole paʻakikī, e koho i na electrons holo i loko o ke alakaʻi mele, mai ka "hua" ka "hua hoʻohui". Aeʻimi hoʻopunipuni loli o ka papa cia - o keia papa, aole ia i hooki i ka e mau. He nui kekahi mau pāʻoihana e hoohuli i ka pololei kala pono i loko o alternating (sine nalu nā mīkini uila) a me ka Hope versa (rectifiers, na alahaka).
