Ifomula yokubala yesithando sokushisa sokungeniswa
Ifomula yokubala yesithando sokushisa sokungeniswa
Ifomula yokubala i-inductance yekhoyili ye-air-core: I=(0.01*D*N*N)/(I/D+0.44)
kuphi:
(1) I-coil inductance I, iyunithi: i-microhenry;
(2) Ububanzi bekhoyili D, iyunithi: cm;
(3) Inombolo yekhoyili ijika N, iyunithi: iyajika;
(4) Ubude bekhoyili I, iyunithi: cm;
Ngokwefomula, i-inductance I ilingana nenani lokujika kuka-N wekhoyili.
I-inductance I imele izici zemvelo zekhoyili ngokwayo futhi ayihlangene nhlobo nobukhulu bamanje. Ngaphandle kwamakhoyili e-inductance akhethekile (i-color code inductance), i-inductance ngokuvamile ayimakwa ngokuqondile kukhoyili, kodwa imakwe ngegama elithile. Ubukhulu be-inductor inductance ngokuyinhloko buncike enanini lokuphenduka (inani lokujika) kwekhoyili, indlela yokusonta, ukuba khona noma ukungabikho komgogodla kazibuthe kanye nempahla yengqikithi kazibuthe, njalonjalo.
Ngokuvamile, lapho ikhoyili iphenduka kakhulu futhi amakhoyili aminyene, i-inductance iba nkulu. Ikhoyili enomgogodla kazibuthe ine-inductance enkulu kunekhoyili engenawo umgogodla kazibuthe; lapho kungeneka khona umnyombo kazibuthe, kukhulu ukuvuleka.
Iyunithi eyisisekelo ye-inductance nguHenry (uHenry ngamafuphi), omelwe uhlamvu “H”. Amayunithi asetshenziswa kakhulu yi-millihenry (mH) kanye ne-microhenry (μH). Ubudlelwano phakathi kwabo yilokhu: 1H=1000mH; 1mH=1000μH.
