Ke kumu hana o ka inductance

ʻO ka inductance ka wili ʻana i ka uea i ke ʻano coil.Ke kahe ka au, e hoʻokumu ʻia kahi māla magnetic ikaika ma nā ʻaoʻao ʻelua o ka coil (inductor).Ma muli o ka hopena o ka induction electromagnetic, e pale ia i ka loli o kēia manawa.No laila, heʻuʻuku ke kū'ēʻana o ka inductance i ka DC (e like me ka pōkole pōkole) a me ke kū'ē kiʻekiʻe i ka AC, aʻo kona kū'ēʻana e pili ana i ke alapine o ka hōʻailona AC.ʻO ke kiʻekiʻe o ke alapine o ka manawa AC e hele ana i ka mea inductive hoʻokahi, ʻoi aku ka nui o ka waiwai kū'ē.

ʻO ka Inductance kahi mea mālama ikehu hiki ke hoʻololi i ka ikehu uila i ka ikehu magnetic a mālama iā ia, maʻamau me hoʻokahi wili.Hoʻokumu ʻia ka inductance mai ka hao-core coil i hoʻohana ʻia e M. Faraday ma ʻEnelani i ka makahiki 1831 e ʻike i ke ʻano o ka induction electromagnetic.He kuleana koʻikoʻi nō hoʻi ka inductance i nā kaapuni uila.
ʻO nā hiʻohiʻona inductance: pili DC: pili i kēlā ma ka kaapuni DC, ʻaʻohe hopena pale ma DC, ua like ia me kahi uea pololei.Ke kū'ē i ka AC: ʻO ka wai e ālai i ka AC a hoʻopuka i kekahi impedance.ʻO ke kiʻekiʻe o ke alapine, ʻoi aku ka nui o ka impedance i hana ʻia e ka coil.

ʻO ka hopena pale o kēia manawa o ka inductance coil: ʻo ka ikaika electromotive i hoʻokomo ʻia iā ia iho i loko o ka coil inductance e kūpaʻa mau i ka hoʻololi ʻana o ka coil.Loaʻa i ka coil inductive kahi hopena pale i ka manawa AC.Kapa ʻia ka hopena paʻa i ka inductive reactance XL, a ʻo ka ʻāpana he ohm.ʻO kona pilina me ka inductance L a me ke alapine AC f he XL=2nfL.Hiki ke hoʻokaʻawale ʻia nā inductors i ke kiʻekiʻe pinepine choke coil a me ka haʻahaʻa haʻahaʻa choke coil.

ʻO ke kani ʻana a me ke koho alapine: Hiki ke hoʻokumu ʻia ke kaapuni hoʻokani LC e ka pilina like o ka inductance coil a me ka capacitor.ʻO ia hoʻi, inā like ke alapine oscillation maoli f0 o ke kaapuni me ke alapine f o ka hōʻailona non-AC, ua like pū ka inductive reactance a me ka capacitive reactance o ke kaapuni, no laila e oscillates ka ikehu electromagnetic i hope a i waho i ka inductance a. capacitance, ʻo ia ke ʻano resonance o ke kaapuni LC.I ka wā o ka resonance, ua like ka reactance inductive a me ka reactance capacitive o ke kaapuni.ʻO ka reactance inductive o ka huina o kēia kaapuni ka mea liʻiliʻi loa, a ʻo ka nui o kēia manawa ka nui loa (e pili ana i ka hōʻailona AC me f = ”f0″).ʻO ka LC resonant circuit ka hana o ke koho ʻana i ke alapine, a hiki ke koho i ka hōʻailona AC me kahi alapine f.
Loaʻa i nā Inductors nā hana o ka kānana ʻana i nā hōʻailona, ​​​​ka walaʻau kānana, ka hoʻopaʻa ʻana i kēia manawa a me ka hoʻopaʻa ʻana i ka interference electromagnetic.
