Ndị Nduzi: Ozizi Isi, Ụdị, na Ngwa
Inductor bụ ihe eletrọniki na-anaghị arụ ọrụ nke na-echekwa ike n'ụdị magnetik. N'ikwu ya n'ụzọ dị mfe, inductor bụ eriri waya nke ọkụ eletrik na-agafe. Mgbe ọkụ eletrik gafere na coil, a na-akpali oghere magnetik, mgbe ọkụ eletrik gbanwere, inductor na-emegide mgbanwe a, na-emepụta voltaji kpọmkwem nke na-emegide mgbanwe nke ọkụ eletrik. Isiokwu a ga-akọwa nke ọma ozizi bụ isi, ụdị inductor, na ojiji ha na ngalaba teknụzụ dị iche iche.

Ụkpụrụ ọrụ
Ọrụ inductors dabere na ụkpụrụ nke induction electromagnetic, nke Michael Faraday kọwara na narị afọ nke 19. Iwu Faraday na-ekwu na mgbanwe na mpaghara magnetik gburugburu onye na-eduzi ihe na-akpali ọkụ eletrik na onye na-eduzi ihe ahụ. N'aka nke ọzọ, iwu Lenz na-ekwu na ntụziaka nke voltaji e tinyere na-emegide ntụziaka nke mgbanwe na ugbu a nke kpatara ubi magnetik.
Usoro bụ isi maka inductance bụ:
\[ V_L = L \frac{di(t)}{dt} \]
Ebe:
– \(V_L \) bụ voltaji gafere inductor
– \( L \) bụ inductance (a tụrụ ya na henries, H)
– \( \frac{di(t)}{dt} \) bụ ọnụego mgbanwe nke ugbu a ka oge na-aga.

– Mpaghara elu na ogologo nke eriri igwe ahụ.
