Waya na-eguzogide ọ na-adị gịrịgịrị ma nguzogide na-abawanye ma ọ bụ na-ebelata

Abstract: Isiokwu a ga-enyocha mgbanwe na nguzogide mgbe waya na-eguzogide na-adị gịrịgịrị. Site n'ịtụle mmekọrịta dị n'etiti waya nguzogide na nke ugbu a na voltaji, anyị ga-akọwa ma mkparị waya na-eguzogide na-eduga n'ịbawanye ma ọ bụ ibelata na nguzogide, wee nyochaa ngwa ya n'ọnọdụ dị iche iche.

okwu mmeghe:

Na ndụ anyị kwa ụbọchị, mgbochi bụ echiche anụ ahụ dị oke mkpa. Otú ọ dị, ọtụtụ ndị ka na-enwe obi abụọ banyere ihe kpatara mgbanwe ndị na-eguzogide. Otu n'ime ajụjụ ndị a bụ, nguzogide ahụ ọ ga-abawanye ma ọ bụ ibelata mgbe waya mgbochi na-adị gịrịgịrị? Edemede a ga-abanyekwu n'okwu a ma nyere ndị na-agụ akwụkwọ aka ịkọwa mgbagwoju anya ha.

1. Mmekọrịta dị n'etiti waya na-eguzogide, ugbu a, na nguzogide

Nke mbụ, anyị kwesịrị ịghọta njikọ dị n'etiti wires ndị na-eguzogide, ugbu a na nguzogide. Dị ka iwu Ohm si kwuo, ugbu a (I) dị nhata na nguzogide (R) yana n'ụzọ dị iche na voltaji (V). Ya bụ, I=V/R. Na usoro a, nguzogide (R) bụ ihe dị mkpa nke waya nguzogide.

2. Thinning nke iguzogide waya: na-akpata mmụba ma ọ bụ ibelata na-eguzogide?

Na-esote, anyị ga-atụle n'ụzọ zuru ezu mgbanwe na nguzogide mgbe waya na-eguzogide na-aghọ thinner. Mgbe waya nguzogide na-adị gịrịgịrị, mpaghara akụkụ ya na-ebelata. Dabere na njikọ dị n'etiti nguzogide na mpaghara mpaghara nke ikuku na-eguzogide (R = ρ L / A, ebe ρ bụ resistivity, L bụ ogologo, na A bụ mpaghara mpaghara), anyị nwere ike ịhụ na a mbelata na mpaghara obe ga-eduga n'ịbawanye nguzogide.

3. Okwu nke thinning iguzogide wires na ngwa ubi

Ọ bụ ezie na ọ bụ ezie na ọ bụ eziokwu na mkparị nke waya na-eguzogide na-eduga n'ịbawanye nkwụsi ike, na ngwa ndị bara uru, anyị nwere ike ịhụ na e nwekwara ihe ngosi ebe nchacha nke waya na-eguzogide na-eduga n'ibelata nkwụsị. Dịka ọmụmaatụ, na ụfọdụ ngwaọrụ nguzogide dị elu, site n'ịchịkwa nha nke waya na-eguzogide, enwere ike nweta ezigbo ngbanwe nke uru nkwụsị ahụ, si otú a na-emeziwanye ihe ziri ezi nke sekit.

Tụkwasị na nke ahụ, na thermistors, mkparị nke waya na-eguzogide nwekwara ike ime ka ibelata nkwụsị. Thermistor bụ akụrụngwa na-eji mgbanwe okpomọkụ gbanwee uru nguzogide. Mgbe okpomọkụ na-ebili, ihe nke waya na-eguzogide ga-agbasawanye, na-eme ka waya na-eguzogide na-adịwanye njọ, si otú ahụ na-eme ka ibelata nkwụsị. A na-eji njirimara a eme ihe n'ọtụtụ ebe n'ọhịa nke nha okpomọkụ na njikwa.

4. Nkwubi okwu

Site na nyocha nke mmekọrịta dị n'etiti waya na-eguzogide na ugbu a na voltaji, anyị nwere ike ikwubi na ịcha waya na-eguzogide ga-eduga n'ịbawanye nguzogide. Otú ọ dị, na ụfọdụ pụrụ iche ngwa ndapụta, na thinning nke iguzogide waya nwekwara ike iduga mbelata na-eguzogide, nke tumadi dabere na ihe e ji mara na ngwa chọrọ.

Nchịkọta:

Edemede a na-eleba anya n'okwu nke mgbanwe nguzogide na-akpata site na mkparị waya ndị na-eguzogide. Na tiori, a thinner iguzogide waya ga-eduga na-abawanye na-eguzogide; Otú ọ dị, na ngwa ndị bara uru, e nwekwara ọnọdụ ndị na-eduga n'ibelata nguzogide. Anyị akpọtụrụla ụfọdụ ikpe na mpaghara ngwa, na-egosipụta ụdị dị iche iche na mgbanwe nke wires na-eguzogide na-ebelata. Site na edemede a, ndị na-agụ nwere ike nweta nghọta zuru oke nke mmetụta nke thinning reswires istance, yana ọnọdụ ngwa ha na njirimara na ngwa bara uru.
