1. Uyini umsebenzi oyinhloko we-transformer?
   • Impendulo: Umsebenzi oyinhloko we-transformer ukushintsha i-voltage yomthombo wamandla kagesi oshintshanayo (AC). Lokhu kwenziwa ngokwandisa (ukwenyusa) noma ukunciphisa (ukwehlisa) i-voltage ngokusekelwe ezidingweni zohlelo lokusebenza.
2. Ama-transformer e-step-up kanye ne-step-down ahluke kanjani emsebenzini wawo?
   • Impendulo: I-transformer yesinyathelo esinyukayo inyusa i-voltage kusukela ku-primary kuya ku-secondary coil, kuyilapho i-transformer yesinyathelo esihlayo inciphisa i-voltage kusukela ku-primary kuya ku-secondary coil.
3. Buyini ubudlelwano phakathi kwenani lamajika kuma-coil ayinhloko nawesibili e-transformer kanye nokuguqulwa kwayo kwe-voltage?
   • Impendulo: Isilinganiso sokuguqulwa kwamandla kagesi silingana ngqo nesilinganiso sokujika. Uma ikhoyili yesibili inamajika amaningi kunekhoyili eyinhloko, iyi-transformer yesinyathelo-phezulu, futhi okuphambene nalokho. Amandla kagesi kukhoyili ngayinye alingana nenani lamajika kuleyo khoyili.
4. Kungani kunesidingo sokwandisa i-voltage yokudlulisa amandla kagesi amabanga amade?
   • Impendulo: Ukwandisa i-voltage kunciphisa ugesi wamandla athile, okubuye kunciphisa ukulahleka kwamandla okumelana emigqeni yokudlulisela. Ugesi ophansi usho ukuthi izintambo ezincane zingasetshenziswa, ezishibhile futhi ezilula ukuzilawula.
