Inductor ea khama

DC resistance AC ke mokhoa o bonolo oa ho re, e ka arola le ho fokotsa lets'oao la AC, kapa ea etsa potoloho e resonant e nang le resistor le capacitor, ea lokisa puo le ho khetha frequency. Inductance coil le capacitor ka ho bapa li ka theha potoloho ea LC tuning. Ke hore, haeba maqhubu a tlhaho a oscillation 0 a potoloho a lekana le maqhubu a lets'oao leo e seng la AC, ts'ebetso ea inductive le capacitive reactance ea potoloho le tsona lia lekana, kahoo matla a motlakase oa motlakase a pota-pota ho ea pele le lipakeng pakeng tsa inductor le capacitor. , e leng ketsahalo ea resonance ea potoloho ea LC. Ha resonant, inductive reactance le capacitive reactance ea potoloho lia lekana ebile lia fetoha, ka hona, karabelo ea inductive ea kakaretso ea potoloho ea potoloho e nyane, mme palo ea hajoale (e bua ka - lets'oao la 0 AC), kahoo potoloho ea LC resonant e na le. mosebetsi oa ho khetha maqhubu, 'me e ka khetha lets'oao la AC la maqhubu a itseng.

Ha maqhubu a lets'oao a phahame, ho bonolo hore a fetisetsoe. Leha ho le joalo, mehala ea matšoao ka kakaretso ha e na lera le sireletsang. Mehala ena ea matšoao e fetoha li-antenna tse ntle haholo ho amohela mefuta eohle ea matšoao a bohlasoa a maqhubu a phahameng tikolohong e haufi. Haeba matšoao ana a behiloe holim'a matšoao a fetisoang a mantlha, a tla fetola le mats'oao a bohlokoa a fetisoang mme a kena-kenane le ts'ebetso e tloaelehileng ea lisebelisoa tsa elektroniki, ka hona, hoa hlokahala ho fokotsa tšitiso ea motlakase (EM) ea lisebelisoa tsa elektroniki. Tlas'a ketso ea selikalikoe sa makenete, le haeba lets'oao le tloaelehileng le le sebetsang le feta hantle, le ka hatella lets'oao la tšitiso e phahameng haholo, mme litšenyehelo li tlase. The magnetic rod inductance coil e boetse e bapala karolo ea bohlokoa ho lerata le fetang, lets'oao la ho hlahloba, ho tsitsisa hona joale le ho hatella tšitiso ea maqhubu a motlakase.
