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.
