Li-inductors ke likarolo tse ka fetolang matla a motlakase hore e be matla a khoheli ebe oa li boloka. Li-inductors li tšoana ka sebopeho le li-transformer, empa li na le moea o le mong feela. Li-inductors li na le inductance e itseng, e thibelang phetoho ea hona joale feela. Haeba inductor e le sebakeng seo ho seng hona joale se phallang, se tla leka ho thibela hona joale ho phalla ho eona ha potoloho e kopantsoe. Haeba inductor e le boemong ba phallo ea hona joale, e tla leka ho boloka hona joale e sa fetohe ha potoloho e khaotsoe.

Li-inductors li boetse li bitsoa chokes, li-reactors le li-reactor tse matla. Inductor ka kakaretso e entsoe ka moralo, matsoeli, sekoaelo se sireletsang, thepa ea ho paka, khouto ea makenete kapa mokokotlo oa tšepe, joalo-joalo. Inductance ke karo-karolelano ea phallo ea makenete ea conductor ho ea hajoale e hlahisang phallo ea makenete e fapanyetsanang ho potoloha conductor ha conductor e feta. motlakase o fapanyetsanang.

Ha DC e ntse e phalla ka har'a inductor, ho na le mohala o tsitsitseng feela oa matla o hlahang ho potoloha, o sa fetoheng ka nako.

Ho ea ka molao oa Faraday oa ho kenya motlakase oa motlakase - magnetism e hlahisa motlakase, mekhoa e fetotsoeng ea matla e tla hlahisa bokhoni ba ho kenya lipheletsong tse peli tsa coil, e lekanang le "mohloli o mocha oa matla".

Li-inductors li arotsoe ka li-self inductors le li-inductors tse peli. Ha ho na le hona joale ka har'a coil, matla a khoheli a tla hlahisoa ho potoloha khoele.

Ha motlakase oa coil o fetoha, matla a khoheli a pota-potileng a tla boela a fetohe ka tsela e nepahetseng.
