Una mea pihana a me kona manaʻo

Elua i lalo papa manaʻo ia laua i kekahi i kekahi, a kaawale ma kekahi dielectric, hoolilo palahalaha mea pihana. 'O kēia ka simplest ka Luna o na capacitors, a i papahana no ka hoʻomāhuahua heteronymic ikehu. Inā ka una honua mea, e hai aku i ka mea e like me ka nui akā, e ku pono ana ma ka modulus, o ka ikaika o ka uila kula ma waena o nā conductors e e pāpālua. Kauoha aku lākiō o kekahi o na conductors a hiki i ke anakahi uila ma waena o ka mea pihana papa kapaia uila nona iho:

C = nā nīnau / U

Inā i ka hoʻoponoponoʻana o Kamehameha o na papa mea ikaika, ka uila nona iho o ka mea pihana hiki ke manao ia a eia i no kekahi kauoha conductors. Ma ka 'āina' o Hawaiʻii kekahi huahelu uila nona iho - Farad (F). Oeaeo mea pihana i ke anakahi uila like no ka huina o na intensities ua loaʻa conductors (E ₁ + E ₂ ... + E _N ). Maʻi lele nui. Ke kumukuai o ka pou nona iho ka pololei hapaʻauhau i ka wahi o ka papa, a inversely hapaʻauhau i ka mamao therebetween. Kēia 'o ia hoʻi ia, ma ka mea e hoʻonui ai i ka pou capacitance o ka mea pihana, ia mea e pono ia e ke kahi nui papa, oiai e hoemi i ka mamao ma waena o lākou. Ke kaumaha ma muli o ka dielectric una mea pihana hiki e:

• Pepa.
• Mika.
• Polystyrene.
• Pālolo.
• Air.

I ka rula o ka mea, e noonoo i ka hana ana o ka pepa mea pihana. Pepa ia me ka paraffin, ua hoʻohana 'ia ma kēia hihia, e like me ka dielectric. Waiho iho la i ka dielectric ma waena o ka pepa kini holehole mai ai i mau a malama like conductors. Ke 'ole holoʻokoʻa ua olokaa mai, ma i i hookomoia hopena a no ka pili i ka uila puni. Kēia kükohu ua waiho i loko o ka hale noho pālolo paha mea hiki ke hooheheeia. I lalo ea mea pihana, a me ka 'ē aʻe malama papaa i na mea maalea, ua like' ole, e like me ka meakino hoʻohana dielectric mea, a ua kapaia ma ka hanohano o ka mea pihana wale. I ka hoʻoponopono pilikia, i ka i ia mea e pono, e imi i ka mea i ike ole mea, mai hoopoina i ka hoʻohana nui characterizing insulator - dielectric a eia i o ka meakino.

Ka Radio hoʻohana wai, a maloo ke ano o capacitors. Wai capacitors i electrolytic pāʻoihana, ma i oxidized Aluminum anuanu ua kau. He kēia waiwai i loko o ka'ōlinolino hihia. Ke electrolyte He He kākoʻo pāʻoihana o boricʻakika a me kekahi'ē aʻe ukuhiia. Maloo pūnaeweleʻano i hanaʻia ma ke pelu ana ekolu holehole mai ai, hoʻokahi Aluminum a me ka 'ē aʻe - he mea hiki ke hooheheeia, a ma waena o ia - he ahu iho la ka gauze impregnated me ka h ÷ electrolyte. I ka'ōwili ua waiho ia ma ka Aluminum hihia, a piha i bitumen. Una mea pihana i ka laulā huahelu o ka palapala noi a me ka haahaa kāki. Eia naʻe, i kēia mau ana hoʻohālike e ole e puku i kā mākou iuo aaoa? No ka mea, o ka ikehu pelane mea pihana mea uuku loa, a kauoha aku loa koke, "pūnāwai". Ka mea, e pono e like me ke kumu o ka uila, akā, ka mea, i hoʻokahi lanakila - wā kauoha aku la i ma ka haʻahaʻa-ia'ku huakai kaapuni koke haawi aku i ka waiho waho ikehu.
