Inductance ndiko kumonyorora waya kuita coil shape.Apo ikozvino inoyerera, simba remagineti richaumbwa kumativi ose maviri ekoiri (inductor).Nekuda kwemhedzisiro ye electromagnetic induction, inotadzisa shanduko yezvino.Naizvozvo, iyo inductance ine kushomeka kudiki kuDC (yakafanana nepfupi pfupi) uye yakakwirira kupikisa AC, uye kushorwa kwayo kunoenderana nehuwandu hweiyo AC chiratidzo.Iyo yakakwirira iyo frequency ye AC ikozvino ichipfuura nepakati yakafanana inductive element, iyo yakakura kukosha kwekupokana.
Inductance chinhu chekuchengetedza simba chinogona kushandura simba remagetsi kuita magineti simba uye kurichengeta, kazhinji nemhepo imwe chete.Inductance yakatanga kubva kune iron-core coil yakashandiswa naM. Faraday kuEngland muna 1831 kuwana chiitiko che electromagnetic induction.Inductance inoitawo basa rakakosha mumaseketi emagetsi.
Inductance maitiro: DC yekubatanidza: inoreva iyo muDC wedunhu, hapana inovharira mhedzisiro paDC, iyo yakaenzana newaya yakatwasuka.Resistance to AC: Mvura inovhara AC uye inoburitsa imwe impedance.Iyo yakakwirira iyo frequency, yakakura iyo impedance inogadzirwa necoil.
Ikozvino inovharira mhedzisiro ye inductance coil: iyo yega-induced electromotive simba mune inductance coil inogara ichipokana nekuchinja kwazvino mucoil.Inductive coil ine inovharira mhedzisiro pa AC ikozvino.Iyo yekuvhara maitiro inonzi inductive reactance XL, uye iyo unit ndeye ohm.Hukama hwayo ne inductance L uye AC frequency f ndeye XL = 2nfL.Inductors inogona kunyanya kukamurwa kuita yakakwira frequency choke coil uye yakaderera frequency choke coil.
Tuning uye frequency kusarudzwa: LC tuning yedunhu inogona kuumbwa nekubatana kwekubatanidza inductance coil uye capacitor.Ndokunge, kana yakasikwa oscillation frequency f0 yedunhu yakaenzana nefrequency f yeiyo isiri-AC chiratidzo, iyo inductive reactance uye capacitive reactance yedunhu zvakare yakaenzana, saka iyo electromagnetic simba oscillates nekudzoka kumashure mune inductance uye. capacitance, inova resonance phenomenon yeLC circuit.Munguva yeresonance, iyo inductive reactance uye capacitive reactance yedunhu yakaenzana uye inodzokera kumashure.Iyo inductive reactance yehuwandu hwazvino hwedunhu idiki, uye huwandu hwazvino ndiyo yakakura (ichireva iyo AC siginecha ine f=”f0″).Iyo LC resonant circuit ine basa rekusarudza frequency, uye inogona kusarudza iyo AC siginecha ine imwe frequency f.
Inductors zvakare ine mabasa ekusefa masaini, kusefa ruzha, kudzikamisa ikozvino uye kudzvanyirira kukanganiswa kwemagetsi.
