Ndekọ arụmọrụ nke eriri inductance bụ nke kachasị nha nke inductance. Na mgbakwunye, n'ikwu okwu n'ozuzu, ọnya waya nwere eriri inductance mgbe niile nwere nguzogide ụfọdụ, nke na-adịkarị obere ma nwee ike ileghara ya anya. Otú ọ dị, mgbe nke ugbu a na-erugharị na ụfọdụ sekit dị nnọọ ukwuu, a pụghị ileghara obere nkwụsị nke eriri igwe anya, n'ihi na nnukwu mmiri ga-eri ike na eriri igwe, na-eme ka eriri ahụ kpoo ọkụ ma ọ bụ ọbụna na-ere ọkụ, ya mere, mgbe ụfọdụ, ọkụ eletrik.

Inductance

Inductance l na-anọchite anya njirimara ebumpụta ụwa nke eriri igwe n'onwe ya, n'agbanyeghị ihe dị ugbu a. Ewezuga eriri inductance pụrụ iche (inductance nwere agba), a na-edokarị inductance akara pụrụ iche na eriri igwe, mana ejiri aha akpọrọ aha. Inductance, nke a makwaara dị ka ọnụọgụ inductance nke onwe, bụ ọnụọgụ anụ ahụ na-egosi ikike ime onwe onye nke inductor. The inductance nke inductor tumadi dabere na ọnụ ọgụgụ nke atụgharị nke eriri igwe, na winding mode, ọnụnọ ma ọ bụ na-anọghị nke isi na ihe nke isi, wdg N'ozuzu, ndị ọzọ eriri igwe atụgharị na denser coils na-ọnya, na. ukwuu inductance. Inductance nke eriri igwe na magnetik isi dị ukwuu karịa nke eriri igwe na-enweghị isi magnetik; Ka nnukwu ikike ndọta nke isi, ka inductance ka ukwuu.

Akụkụ bụ isi nke inductance bụ Henry (Hen maka mkpụmkpụ), nke mkpụrụedemede "H" nọchiri anya ya. Nkeji a na-ejikarị bụ milli-Heng (mH) na micro-Heng (μH), na mmekọrịta dị n'etiti ha bụ:

1H=1000mH

1mH=1000μH

Inductive mmeghachi omume

Oke nguzogide nke eriri inductance na AC ugbu a ka a na-akpọ inductance XL, yana ohm dị ka unit na ω dị ka akara. Mmekọrịta ya na inductance L na AC ugboro F bụ XL=2πfL.

Ihe dị mma

Ọdịmma ihe Q bụ ọnụọgụ anụ ahụ na-anọchite anya ogo eriri igwe, yana Q bụ oke nke inductance XL na nguzogide ya, ya bụ, Q = XL/R. inductor na-arụ ọrụ n'okpuru voltaji AC ụfọdụ ugboro. Ọnụ ọgụgụ dị elu nke Q nke inductor, nke dị ntakịrị na-efu ma na-arụ ọrụ nke ọma.
