Ko te inductance he whakawiri i te waea ki te hanga porowhita. Ka rere te ia, ka puta he papa autō kaha ki nga pito e rua o te porowhita (inductor). Na te kaha o te whakaurunga hiko, ka aukati i te huringa o naianei. Na reira, ko te inductance he iti te parenga ki te DC (he rite ki te waahi poto) me te kaha o te kaha ki te AC, a, ko tana parenga e pa ana ki te auau o te tohu AC. Ko te teitei o te auau o te naianei AC e haere ana i roto i taua huānga inductive, ka nui ake te uara parenga.
Ko te Inductance he huānga rokiroki pūngao ka taea te huri i te pūngao hiko ki te pūngao autō me te penapena, te tikanga kotahi anake te awhiowhio. I ahu mai te inductance i te porowhita rino-matua i whakamahia e M. Faraday i Ingarangi i te tau 1831 ki te kite i te ahuatanga o te whakaurunga hiko. He mahi nui ano te inductance i roto i nga iahiko hiko.
Ko nga ahuatanga o te inductance: hononga DC: e pa ana ki tera i roto i te ara iahiko DC, karekau he paanga aukati ki te DC, he rite ki te waea tika. Te ātete ki te AC: Ko te wai e aukati ana i te AC me te whakaputa i tetahi aukati. Ko te teitei o te auau, ko te nui ake o te impedance i hangaia e te coil.
Ko te paanga aukati o naianei o te coil inductance: ko te kaha hiko hiko i roto i te coil inductance he aukati tonu ki te huringa o naianei i roto i te coil. Ko te porowhita inductive he mana aukati i runga i te naianei AC. Ko te paanga aukati ka kiia ko te tauhohenga inductive XL, a ko te waeine he ohm. Ko tona hononga ki te inductance L me te auau AC f ko XL=2nfL. Ka taea te wehea te nuinga o nga Inductors ki roto i te kooowao i te waa teitei me te iti o te koooo.
Whakaritea me te kowhiringa auau: Ka taea te hanga iahiko LC ma te hononga whakarara o te coil inductance me te punga. Arā, ki te rite te auau oscillation māori f0 o te iahiko ki te auau f o te tohu kore-AC, he rite hoki te tauhohenga inductive me te capacitive reactance o te ara iahiko, na reira ka ohooho te hiko hiko i roto i te inductance me te capacitance, koinei te ahuatanga o te resonance o te iahiko LC. I te wa o te haruru, he rite te tauhohenga inductive me te tauhohenga capacitive o te ara iahiko, me te whakamuri. Ko te tauhohenga inductive o te katoa o ia iahiko ko te iti rawa, a ko te nui o naianei ko te nui rawa (e tohu ana ki te tohu AC me te f = ”f0″). Ko te iahiko resonant LC te mahi ki te kowhiri i te auau, a ka taea te kowhiri i te tohu AC me tetahi auau f.
He mahi ano hoki nga Inductors ki te tātari tohu, ki te tarai haruru, ki te whakapumau i naianei me te aukati i te pokanoa hiko.
