'O ka mea mana ka mana i ka'ike lewa: ka'enela a me nā'ano nui

Nā ma ka hana, a me ka maʻamau o ke ola pinepine pono i ka hoʻokumu o ka helu nui o ka maikaʻi a me ka io ka pila 'āhewa' ana. Ua Ua akaka ia me ka electrification o na kino, a me ka electrostatic hoʻokomo i ka hana ia hiki ole. Ke huli nei e makemake'oe i kahi polokalamu kūikawā. 'O kēia'ano mea he mea mana.

'O ka papa hana he polokalamu pa'akikī kēia me kahi dialectric e ho'oka'awale ana i nā papa'elua. He mea nui ka lahilahi o ka lahilahi o kēia dielectric i ka ho'ohālikelike'ana i ka nui o kēia mau papa ho'okahi,'o ia ho'i, nā alaka'i.

Ka simplest ano o ka uila capacitive mea mea he palahalaha mea pihana, i mea he luna 'o nā papa metala hoʻokaʻawaleʻia ma ka dielectric. Inā ho'okomo'ia ka mana uila i kēia mau papa, a laila ua aneane ka nui o ka ikaika o ka māmā elela e kū ana i waena o lākou a'elua paha ka nui me ka like'ole o ho'okahi o kēia mau papa.

Ka mea nui wale anakahi o keia'ōnaehana ka uila capacitance. Uila capacitance lākou, no ka mea pihana ma ka hua'ōlelo o Electro kumu o ka lākiō o ka malama ana o kekahi o na papa i ke anakahi uila noi ma waena o nā conductors o keia mea. Ma ke'ano laulā, e nānā like ka mana o ka mea mana i kēia:

C = q / U

Inā noho mau ke kūlana o nā papa i ka manawa no ka manawa lō'ihi, hiki ke ho'omau i ka mana o ka pu'upu'u (me ka nānā'ole o nā palena kūpono o ka uku ma nā papa).

I ka International System of Measure Measures, ua ana'ia ka mana o ka mea ho'okomo i Farad (F). Ma muli o kēia'ano ho'ohālikelike, kahi i'ike'ia i ke'ano o ka manalala o ia mea, kahi e like me ka voltage ma waena o nā elelelectric he ho'okahi volt, a'o ka nui o ka uku i hā'awi'ia i nā papa i like ia me ka paila ho'okahi.

'O ka mea'oia'i'o, he'ano nui loa ka mea ho'okahi, no laila ke ho'ohana pinepine nei i nā unite like me nā microfarads, nanofarads a me nā picofarads.

'O ka mana o ka manala o kekahi pona kīlaha e hilina'i pono ma kahi o kāna mau papa a ho'onui i ka manawa e emi ai ka mamao ma waena o lākou. No ka ho'onui nui'ana i ka manahoila o kēia mau polokalamu, lawe'ia nā mea ho'okele me nā elelelectric like'ole.

'O ka pinepine, nā pāpili no nā papa hana e hana'ia me nā wili'ele'ele, a'o ka pepa nui ke pepa, ka mica a me nā kāmeka. E like me nā mea i hana'ia ma ke kumu no nā mealectlectric e hiki i nā capacitors ke lawe i ko lākou mau inoa - pepa, kahu, ka makani, mica. 'O kahi palahalaha nui loa i loa'a i nā lāpuni'āpana electrolytic, no ka mea, he nui nā mākia eletani kūpono. Ma muli o kēia mau'ona, ho'ohana pono'ia lākou i nā mea hana hale, a me nā mea kikowaena o ka mana elee.

'O ka condensers kekahi o nā mea'onike pono'ole loa, me ka'ole hiki'ole ke hana i ka nui o nā hale a me nā pono kīwī.
