Inkcazo yeinductor

Inductorngumlinganiselo wokuqukuqela kwemagnethi yocingo ukuya kweli xesha livelisa imagnethi etshintshanayo, ukuqukuqela kwemagnethi kwenziwa ngaphakathi najikeleze ucingo xa umsinga otshintshanayo udlula ngocingo.

Ngokomthetho kaFaraday we-Electro-Magnetic, umgca wemagnethi oguqukayo uya kuvelisa amandla athotyiweyo kuzo zombini iziphelo zekhoyili, elilingana "nomthombo wamandla omtsha". Xa i-loop evaliweyo yenziwe, le nto inokuthi ibangele iya kuvelisa i-current induced current. Kuyaziwa kumthetho weLenz ukuba inani elipheleleyo lemigca yemagnethi eveliswa yi-current induced kufuneka izame ukuthintela utshintsho lwemigca yemagnethi yasekuqaleni. Ekubeni utshintsho lwangaphambili lwemigca yamagnetic luvela kwiinguqu zangaphandle zangaphandle zamandla, i-coil inductor ineempawu zokuthintela utshintsho lwangoku kwisiphaluka se-AC kwisiphumo senjongo.

I-coil ye-inductor inesimo esifanayo kwi-inertia kwi-mechanics, kwaye ibizwa ngokuba yi-self-induction kumbane. Ngokuqhelekileyo, xa i-knife switch ivuliwe okanye ivuliwe, i-spark iya kwenzeka, ebangelwa ubuninzi obuphezulu obubangelwa yi-self-induction phenomenon.

Ngamafutshane, xa i-coil ye-inductor idibaniswe kumandla ombane we-AC, umgca wemagnethi ngaphakathi kwekhoyili uya kutshintsha ngokutshintshana ngoku, okukhokelela ekufakweni kwe-electromagnetic rhoqo kwikhoyili. La mandla e-electromotive abangelwa utshintsho lwangoku lwekhoyili ngokwayo ibizwa ngokuba "i-self-induced electromotive force".

Ingabonwa ukuba i-inductance kuphela iparameter ehambelana nenani leekhoyili, ubungakanani kunye nokuma kwekhoyili kunye nephakathi. Ingumlinganiselo we-inertia ye-coil ye-inductance kwaye ayinanto yakwenza nombane osetyenzisiweyo.

InductorkwayeUmtshintshi

Ikhoyili ye-inductance: Xa kukho umsinga kucingo, umhlaba wemagnethi wakhiwe ngeenxa zonke kuwo. Ngokwesiqhelo sijija ucingo lube yicoil ukunyusa umhlaba wemagnethi ngaphakathi kwicoil. Iikhoyili ze-inductance zenziwa ngocingo lokusonga (ngocingo olunameleli, umsonto osongelweyo okanye ucingo olungenanto. ngqukuva ngokungqukuva (iingcingo zomoya ezigqunyiweyo ukusuka kwenye) zijikeleze ityhubhu yokugquma (isigqubuthelo, undoqo wentsimbi okanye undoqo wemagnethi) Ngokubanzi, ikhoyili eguquliweyo inojiko olunye kuphela.

Umtshintshi: I-coil inductance ihamba ngotshintsho lwangoku, kungekuphela kwiziphelo ezimbini zombane wabo owenziweyo, kodwa inokwenza i-coil induced voltage ekufutshane, le nto ibizwa ngokuba yi-self induction. Iikhoyili ezimbini ezingadityaniswanga enye kwenye kodwa zisondelelene kwaye zine-electromagnetic induction phakathi komnye zibizwa ngokuba zii-transformers.
