Ụkpụrụ nke inductor na-echekwa ike eletrik

Ọrụ bụ isi nke inductance bụ ịchekwa ihe dị ugbu a (ịchekwa ike eletrik n'ụdị magnetik), mana ọ nweghị ike ịchekwa ugbu a ozugbo (nke ugbu a nwere ike gafere site na eriri inductor na-enweghị mgbochi).

Isi ọrụ nke capacitance bụ ịchekwa ihe dị ugbu a (ịchekwa ọkụ eletrik ozugbo na efere capacitor), mana ọ nweghị ike ịchekwa ihe ọzọ ugbu a (mgbanwe nke ugbu a nwere ike gafere site na capacitor n'enweghị ihe mgbochi).

Ụdị ọzọ nke inductance bụ nke onwe.eriri inductance

N'afọ 1832, Henry, onye ọkà mmụta sayensị America, bipụtara otu akwụkwọ na ihe omume ntinye onwe onye. N'ihi ihe dị mkpa Henry nyere n'ihe gbasara mmekọ onwe onye, ​​ndị mmadụ na-akpọ unit of inductance Henry, nke akpọrọ Henry.

Ihe omume iwebata onwe ya bụ ihe Henry chọpụtara na mberede mgbe ọ na-eme nnwale electromagnet. N'August 1829, mgbe ụlọ akwụkwọ ahụ nọ na ezumike, Henry nọ na-amụ electromagnets. Ọ chọpụtara na eriri igwe na-emepụta ọkụ na-atụghị anya ya mgbe ike kwụsịrị. N'ime ezumike okpomọkụ nke afọ na-esote, Henry gara n'ihu na-amụ nyocha ndị metụtara ntinye onwe onye.

N'ikpeazụ, n'afọ 1832, e bipụtara akwụkwọ iji kwubie na n'ime eriri igwe nwere ugbu a, mgbe mgbanwe dị ugbu a, a ga-emepụta ike electromotive (voltaji) na-eme ka ọ nọgide na-adị ugbu a. Ya mere, mgbe a kwụsịrị ike ọkụ nke eriri igwe, nke ugbu a na-ebelata ozugbo, na eriri igwe ga-emepụta voltaji dị oke elu, mgbe ahụ, ọkụ ọkụ Henry hụrụ ga-apụta (oke voltaji nwere ike ionize ikuku na mkpụmkpụ-circuit iji mepụta sparks).

Igwe ihe na-eme onwe ya

Faraday achọpụtala ihe dị n'ime induction electromagnetic, ihe kachasị mkpa bụ na ngbanwe magnetik na-agbanwe ga-ebute ike electromotive.

Stable direct current na-aga n'ihu n'otu ụzọ. N'ime oghere mechiri emechi, ugbu a anaghị agbanwe agbanwe, yabụ ugbu a na-asọfe na eriri igwe anaghị agbanwe agbanwe, ngbanwe magnetik ya agaghị agbanwe. Ọ bụrụ na ngbanwe magnetik agbanweghị, ọ nweghị ike electromotive ga-eme ka a ga-emepụta, yabụ ugbu a nwere ike ịgafe eriri igwe inductor ngwa ngwa n'enweghị ihe mgbochi.

Na sekit AC, ntụzịaka na ịdị ukwuu nke ugbu a ga-agbanwe ka oge na-aga. Mgbe AC ​​na-agafe eriri inductor, ka ịdị ukwuu na ntụzịaka nke ugbu a na-agbanwe, mgbanwe magnetik gburugburu inductor ga-agbanwekwa mgbe niile. Mgbanwe nke magnetik flux ga-eme ka ọgbọ nke ike electromotive, na ike electromotive a na-egbochi njedebe nke AC!

N'ezie, ihe mgbochi a anaghị egbochi AC ịgafe 100%, mana ọ na-eme ka ihe isi ike nke AC gafere (mmụba na-abawanye). N'ime usoro igbochi AC na-agafe, akụkụ nke ike eletrik na-agbanwe n'ụdị oghere magnet ma chekwaa na inductor. Nke a bụ ụkpụrụ nke inductor na-echekwa ike eletrik

Ụkpụrụ nke ịchekwa na ịtọhapụ ike eletrik bụ usoro dị mfe:

Mgbe eriri igwe dị ugbu a na-abawanye - na-eme ka mgbawa magnetik gbara ya gburugburu gbanwee—mgbanwe ndọta - na-ebute ike eletrọnịkị na-atụgharị (na-echekwa ike eletrik) - na-egbochi ugbu a ka ọ ghara ịba ụba.

Mgbe eriri igwe dị ugbu a na-ebelata - na-eme ka ikuku magnetik gbara ya gburugburu gbanwee - mgbanwe ndọta - na-emepụta otu ntụziaka ahụ na-ebute ike electromotive (na-ahapụ ike eletrik) - na-egbochi ugbu a ka ọ ghara ibelata.

N'okwu, onye inductor bụ onye na-eche nche, na-ejigide ọnọdụ mbụ! Ọ kpọrọ mgbanwe asị ma mee ihe iji gbochie mgbanwe nke ugbu a!

Inductor dị ka ebe nchekwa mmiri AC. Mgbe ihe dị ugbu a dị na sekit buru ibu, ọ na-echekwa akụkụ ya, ma mgbe nke ugbu a dị ntakịrị, ọ na-ahapụ ya ka ọ gbakwụnye!
