ʻO ka manaʻo o ke au uila

I ka electromagnetism, ua kapa ʻia ka nui o ka uila e hele ana ma nā ʻāpana keʻa o kahi conductor i kēlā me kēia manawa i kapa ʻia ʻo ka ikaika o kēia manawa, a i ʻole ka uila uila. ʻO ka hōʻailona no kēia manawa ʻo I, a ʻo ka ʻāpana he ampere (A), a i ʻole "A" wale nō (André-Marie Ampère, 1775-1836, physicist Farani a me chemist, nāna i hana i nā hoʻokō koʻikoʻi i ke aʻo ʻana i nā hopena electromagnetic a hāʻawi pū kekahi i nā haʻawina. i ka makemakika a me ka physics Ua kapa ʻia ka ʻāpana honua o ke au uila, ampere, ma muli o kona inoa inoa).

[2] I ka uila, ua ʻōlelo ʻia ʻo ke kuhikuhi o ke kahe kuhikuhi ʻana o nā uku maikaʻi ʻo ia ke kuhikuhi o ke au. Eia kekahi, ma ka ʻenekinia, ua hoʻohana ʻia ka ʻaoʻao o ke kahe ʻana o nā uku kūpono e like me ke kuhikuhi o ke au. Hōʻike ʻia ka nui o ke au e ka uku Q e kahe ana ma ka ʻāpana keʻa o ka mea hoʻokele i kēlā me kēia manawa, i kapa ʻia ʻo ka ikaika o kēia manawa.
