I-transformer
I-transformer iyingxenye engenakuphikiswa edlulisela amandla kagesi kusuka kumjikelezo owodwa kagesi kwesinye isifunda, noma amasekethe amaningi.
Ukuhlukahluka kwamanje kunoma yiliphi ikhoyili elilodwa le-transformer kukhiqiza i-flux ehlukahlukene yobunzima e-Transformer's Core, okufumana amandla ahlukahlukene kagesi kuwo wonke amanye amakhoyili azungeze umnyombo ofanayo. Amandla kagesi angadluliselwa phakathi kwamakhoyili ahlukene ngaphandle kokuxhumeka kwensimbi (okusebenzayo) phakathi kweziyingi ezimbili. Umthetho kaFaraday wokungeniswa, otholwe ngonyaka we-1831, uchaza umphumela we-voltage voltage kunoma iyiphi ikhoyili ngenxa yokushintsha umkhuhlane oguqukayo oguqulwe yikhoyili.
Abaguquli bavame ukusetshenziselwa ukwandisa ama-voltages aphansi akhuphukayo (i-step-up transformer) noma anciphe ama-voltages aphezulu aphansi (ahamba nge-transformer ephansi (kanye nokuhlanganisa izigaba zemibuthano yokusebenzisa iziginali . Abaguquli nabo bangasetshenziselwa ukuhlala bodwa, lapho ivolula lilingana namandla kagesi, ngamakhoyili ahlukene hhayi ngogesi. Kusukela kwasungulwa kwe-transformer yokuqala eguqukayo njalo ngo-1885, abaguquli sebebalulekile ekudluliseleni, ekusatshalalisweni nasekusetshenzisweni kwamandla kagesi kwamanje. Uhla olubanzi lwemiklamo ye-transformer luhlangabezana nezinhlelo zokusebenza zamandla kagesi nezenzilegesi. Abaguquli bahla ngosayizi kusuka ku-RF Transformers ngaphansi kwesentimitha cubic ngevolumu, kumayunithi anesisindo samakhulu amathani asetshenziselwa ukuxhumanisa igridi yamandla.
