• Nā ʻano alakaʻi
• Nā laʻana o nā mea conductive

ʻO ka mea conductive ʻO lākou ka poʻe e hāʻawi iki i ke kūpaʻa i ka hala o ka uila. Hiki i nā uila uila ke kaʻawale ma o nā mea no ka mea ua nakinaki liʻiliʻi ʻia lākou i nā ʻoma a hiki ke alakaʻi i ka uila. O kahi laʻana: aluminika, keleawe, nikala, gula.

ʻOiai ʻo nā mea āpau e ʻae i ka lawe ʻana o ka uila i kekahi kekelē, ʻo ka poʻe e hana maikaʻi loa ia e ʻike ʻia ma ke ʻano he alakaʻi, ʻoiai nā mea e ʻae ʻole e hele i ka uila nā mea hoʻopili. Aia kahi pae waena ma waena o nā mea i hana ʻia me nā mea semiconductor, e hana nei ma ke ʻano he insulator i kekahi mau ʻano akā hiki ke hoʻololi i kā lākou conductivity e like me nā kūlana i hoʻokau ʻia ai lākou.

ʻO Chemically, ke kaʻina e hana me nā mea conductive ʻo ia kekahi o nā electron e hele manuahi mai kekahi atom i kahi ʻē aʻe ma o ke kaʻina o ka ʻokoʻa i waena o nā wēlau o ka mea alakaʻi. ʻO kēia neʻe ʻana o nā electrons ke au uila.

ʻO nā mea kalaiwa, ʻo ia nā mea i loaʻa ka helu nui o nā uila uila manuahi e neʻe ma waena o nā mea, e hoʻoili maʻalahi ana i ka uku mai kekahi mea a i kekahi. E wehewehe i kēia mau mea, i nā manawa he nui e hoʻohālikelike ʻia me kahi paipu e holo ai kahi kahe o ka wai.

ʻAʻole kūlike nā ʻano o ka conductivity i nā kūlana ʻekolu o ka mea. I ke kumu o nā wai, pili ka conductivity i ke kū ʻana o nā paʻakai i ka hopena, ʻoiai i nā mea paʻa, pili ka conductivity i nā band valence a me ka hoʻokumu ʻana o kahi ao electron.

Hiki iā ia ke lawelawe iā ʻoe:

• Nā mea Semiconductor
• Nā mea hoʻoheheʻe
• Nā mea hana Superconducting

Nā ʻano alakaʻi

Wahi a ke ala e lawe ʻia ai ka conduction a hoʻokumu ʻia, hoʻolaha ʻia nā mea o kēia ʻano penei:

• Nā mea hoʻoheheʻe hao. ʻO lākou nā mea i loaʻa i kahi uila uila, ʻoiai nā mea lawe i nā koina he mau uila uila. Hana ʻia kēia no ka mea ʻo kēia metala nā metala a me nā mea hoʻohui.
• Nā alakaʻi uila. ʻO lākou nā mea i loaʻa kahi ʻano ionic type, kahi e hoʻokaʻawale a hapa paha nā mea, e hana ana i nā iona maikaʻi a maikaʻi ʻole paha, ʻo ia nā mea lawe ukana. Eia ke ala o ka uila i kū i ka laina me kahi neʻe o nā mea a me kahi hopena kemika.
• Nā mea conductive kinoea. ʻO lākou kēlā mau ʻenekini i hoʻopili ʻia (ua lilo a loaʻa paha nā uila) a no laila ua loaʻa ka hiki ke alakaʻi i ka uila. ʻOiai ʻaʻole lākou e hoʻohana pinepine ʻia, he gas ka ea a ma lalo o kekahi mau ʻano he mea lawe uila ʻo ia ka uila, i hōʻike ʻia e nā uila a me nā hoʻokuʻu uila o kēia ʻano.

Nā laʻana o nā mea conductive

(*) Kālā kālā maʻemaʻe: ʻO ke kinona i ʻike ʻia ke alakaʻi ʻoi loa o ka uila.
(**) Keleawe paʻakikī: ʻOiai ʻaʻole maikaʻi e like me ke kālā, ʻoi aku ka liʻiliʻi a no laila hoʻohana nui ʻia.
