ʻAtikala e pili ana i ka wehewehe ʻana o ka capacitor
ʻO ka wehewehe ʻana o ka capacitor he mea hana e mālama i ka hoʻouku uila a me ka ikehu hiki ke uila. ʻO ka capacitor maʻalahi he mau papa a i ʻole nā pepa ʻelua-alakaʻi i kau kokoke ʻia akā ʻaʻole e hoʻopā kekahi i kekahi a ua hoʻokaʻawale ʻia e kahi insulator a i ʻole kahi vacuum. ʻO nā conductors nā mea hiki ke alakaʻi i ke au uila e like me nā metala, ʻoiai ʻo nā insulators nā mea hiki ʻole ke alakaʻi i ke au uila e like me ka plastic.
I ka wā mua, ʻaʻole i hoʻopiha ʻia nā alakaʻi ʻelua i ka uila a i ʻole ke kūlike ʻole o ka uila. I mea e hoʻopiha maikaʻi ʻia ai kekahi alakaʻi a hoʻopiha maikaʻi ʻole ʻia kekahi alakaʻi, a laila pono e hoʻoili ʻia nā electrons mai kekahi alakaʻi i kekahi. Aia nā electrons ma luna o ka ʻili o ka ʻātoma, no laila maʻalahi lākou e neʻe. Ma hope o ka neʻe ʻana o nā electrons mai kekahi alakaʻi i kekahi, loaʻa i kekahi o nā alakaʻi ka nui o nā electrons (nele i nā protons).
i lilo ai ia i mea hoʻopiʻi maikaʻi ʻole, ʻoiai ʻo ke alakaʻi ʻē aʻe he hemahema electron (proton keu) i lilo ai ia i mea hoʻopiʻi maikaʻi. Ua nānā hou ʻia kahi wehewehe kikoʻī o ke kaʻina hana o ka hoʻopiʻi ʻana i nā uku uila ma nā capacitors ma ke kumuhana o ka mālama ʻana i ka ikehu uila i loko o nā capacitors.
E like me ka mea i hōʻike ʻia ma ke kiʻi ma ka ʻaoʻao, ua hoʻopiʻi maikaʻi ʻia kekahi o nā papa alakaʻi (+Q) ʻoiai ua hoʻopiʻi maikaʻi ʻole ʻia kekahi papa alakaʻi (-Q). Ua like ka hoʻopiʻi uila i kēlā me kēia papa akā he hōʻailona kū'ē ia no laila ʻo ka hoʻopiʻi holoʻokoʻa he ʻole (QQ = 0). ʻO ke ola ʻana o kahi hoʻopiʻi uila me ka nui like a me ka hōʻailona kū'ē ma kēlā me kēia papa e hoʻoulu ai i kahi ʻokoʻa hiki ma waena o nā papa ʻelua. ʻOi aku ka kiʻekiʻe o ka hiki uila o ke alakaʻi i hoʻopiʻi maikaʻi ʻia, ʻoiai ʻoi aku ka haʻahaʻa o ka hiki uila o ke alakaʻi i hoʻopiʻi maikaʻi ʻia. I nā huaʻōlelo ʻē aʻe, aia kahi kahua uila ma waena o nā alakaʻi ʻelua i hoʻopiʻi ʻia, kahi e hele ai ke kuhikuhi o ke kahua uila mai ka hoʻopiʻi maikaʻi a i ka hoʻopiʻi maikaʻi ʻole. E like me ka mea i kūkākūkā ʻia ma ke kumuhana o ka ikehu hiki uila, inā he kahua uila a i ʻole he ʻokoʻa o ka hiki uila ma waena o nā papa alakaʻi ʻelua, pono e loaʻa ka ikehu hiki uila i nā papa ʻelua.
ʻO ka ikehu hiki ke hana i ka hana. Inā mālama ka capacitor i ka ikehu hiki ke hana uila, hiki i ka capacitor ke hana i ka hana. ʻO ka ʻoiaʻiʻo, he nui nā hoʻohana o nā capacitors i ke ola o kēlā me kēia lā. ʻO nā capacitors kekahi o nā ʻāpana koʻikoʻi i nā kaapuni uila, kahi i lilo ai nā kaapuni uila i kumu o nā mea uila like ʻole.
