Ngokuqhubeka okuqhubekayo kobuchwepheshe, isidingo semishini kagesi sikhula usuku nosuku. Futhi enye yezingxenye ezibalulekile, intambo yokumelana, idlala indima ebalulekile. I-Resistance wire iyingxenye esetshenziselwa ukulawula yamanje kanye ne-voltage, evame ukutholakala kumishini ehlukahlukene kagesi. Lesi sihloko sizokwethula imingcele yokucaciswa kwezintambo zokumelana.

I-Resistance wire iyintambo encane eyenziwe ngezinto ezikhethekile ezingaveza izici zokumelana. Ngokuvamile kwenziwa ngezinsimbi noma ama-alloys, njenge-nickel chromium alloy, iron chromium aluminium, njll. Ngokwezidingo ezihlukene zohlelo lokusebenza, izintambo zokumelana zingaba nobubanzi obuhlukene, ubude, namanani okumelana.

Okokuqala, ake sibheke ububanzi bocingo lokumelana. Ububanzi ubude bengxenye yomugqa onqamulayo wentambo yokumelana, ngokuvamile ikalwa ngamamilimitha (mm). Ubukhulu bobubanzi buthinta ngokuqondile ukuqhutshwa kocingo lokumelana. Ngokuvamile, lapho ububanzi buba mncane, bukhulu inani lokumelana nocingo lokumelana; Ukuqina kobubanzi, liba lincane inani lokumelana lentambo yokumelana. Ngakho-ke lapho ukhetha ucingo lokumelana, kuyadingeka ukunquma usayizi wobubanzi ngokusekelwe ezidingweni ezithile zesifunda.

Okwesibili, ubude bocingo lokumelana nakho kuyipharamitha ebalulekile yokucacisa. Ubude bunquma usayizi ophelele wentambo yokumelana, ngokuvamile ikalwa ngamamitha (m). Ubukhulu bobude ngokuvamile bunqunywa umklamo wesifunda, futhi ukukhetha ubude obufanele ngokusekelwe ezidingweni zamanje kanye ne-voltage kungaqinisekisa ukusebenza okuzinzile kocingo lokumelana.

Ekugcineni, inani lokumelana lentambo yokumelana liyipharamitha eyinhloko. Inani lokumelana limelela izinga lokumelana kwentambo yokumelana neyamanje, ngokuvamile ikalwa ngama-ohms (Ω). Inani lokumelana lingafinyelelwa ngokulungisa impahla, ububanzi, nobude bocingo lokumelana. Kuzinhlelo zokusebenza ezingokoqobo, singahlangabezana nezidingo zesekethe ezihlukene ngokuxhuma izintambo zokumelana namanani ahlukene okumelana.

Ngaphandle kokucaciswa okuthathu okuyinhloko okukhulunywe ngenhla, kukhona nezinye izici ezithinta ukusebenza kocingo lokumelana. Isibonelo, ukukhethwa kwezinto kunomthelela omkhulu ekuzinzeni nasekuqhubekiseni izintambo zokumelana; Ukwelashwa okungaphezulu kungathuthukisa ukumelana nokugqwala kwezintambo eziqinile; Ukushisa kwe-ambient nakho kunomthelela ekusebenzeni kokusebenza kwezintambo zokumelana, njalonjalo.

Kafushane, ukukhethwa kokucaciswa kwentambo yokumelana kudinga ukucatshangelwa okuphelele kwezici ezihlukahlukene. Ngokusho kwezidingo zesifunda, ukunquma ububanzi obufanele, ubude, kanye nenani lokumelana, ngenkathi unaka ukukhethwa kwezinto ezibonakalayo nokuphathwa kwendawo, kungaqinisekisa ukusebenza okuvamile kocingo lokumelana kumadivayisi kagesi.

Ngokuqhubeka okuqhubekayo kobuchwepheshe, isidingo sezintambo zokumelana kumadivayisi kagesi naso sihlala sivela. Ngokuzayo, singabona kusengaphambili ukuthi izintambo zokumelana zizoba zincane, zizinze, futhi zisebenze kahle kakhulu. Kungakhathaliseki ukuthi ama-smartphone, amakhompyutha, izimoto, noma eminye imikhiqizo ye-elekthronikhi emisha, izintambo zokumelana nezintambo zizoqhubeka zidlala indima ebalulekile, zilethe ukunethezeka nenjabulo eyengeziwe kubantu.

Okungenhla yisingeniso sokucaciswa kanye nemingcele yezintambo zokumelana. Ngethemba ukuthi lesi sihloko singanikeza abafundi ukuqonda okujulile kwezintambo zokumelana futhi sinikeze isiqondiso kuzinhlelo zokusebenza ezingokoqobo. Nakuba izintambo zokumelana nezincane, zidlala indima ebalulekile emishinini kagesi, zikhuthaza ukuthuthukiswa kobuchwepheshe kanye nenqubekelaphambili yomphakathi wesintu. Masibheke phambili ekudaleni amathuba engeziwe okuthuthukiswa kwezintambo zokumelana esikhathini esizayo!
