Nkewa site inductance ụdị: ofu inductance, agbanwe inductance.

Nkewa dịka njirimara nke magnetik: oghere eriri, eriri ferrite, eriri igwe, ọla kọpa.

Nkewa site na ọrụ nke ọrụ: eriri mpi, eriri oscillating, eriri igwe, eriri ọnya, eriri igwe.

Nkewa site na winding windo: otu eriri oyi akwa, eriri igwe, eriri mmanụ a honeyụ.

Njirimara njirimara kachasị nke eriri inductance:

1.Arụ ọrụ L

Inductance L na-anọchi anya njirimara sitere na eriri igwe ahụ n'onwe ya, na-enweghị onwe ya na ụdị ọnọdụ ugbu a.

2.ọrụ XL

Ogo nke eriri inductance na ngọngọ nke AC ugbu a ka a na-akpọ induction reactance XL, ngalaba ahụ bụ ohm. Mmekọrịta ya na inductance L na ntụgharị oge ọzọ F bụ XL = 2πfL

3.Ọdịmma nke Q

Ọdịmma ogo Q bụ ọnụọgụ anụ ahụ na-anọchi anya ncha mma, Q bụ nha nke nguzogide nrụpụta XL na nguzogide ya, ya bụ: Q = XL / R.
