Kunezindlela ezimbili eziphambili zokuxhuma amabhethri: Kuchungechunge futhi ngokufana.

Lapho uxhuma amabhethri ochungechungeni, i-terminal enhle yebhethri elilodwa ixhumeke kwisiginali esingesihle sebhethri elilandelayo, ukukhulisa kahle ivola eliphelele lohlelo.Isibonelo, ukuxhuma amabhethri amabili we-12V ngochungechunge kuzoholela kumandla kagesi aphelele we-24V.

Lapho uxhuma amabhethri ngokufana, ama-terminals amahle awo wonke amabhethri axhumeke ndawonye, futhi ama-terminals amabi nawo axhunyiwe ndawonye.Lokhu kwandisa umthamo ophelele (amahora we-Ampere) wohlelo, kepha i-voltage ihlala injalo.Isibonelo, ukuxhuma amabhethri amabili we-12v ngokufana azophumela ephelele yama-24h, kepha i-voltage isazoba yi-12V.

Kungenzeka futhi ukuxhuma amabhethri ngokuhlanganiswa kochungechunge kanye nokufana, okubizwa ngokuthi "ukuhambisana" nokucushwa "ukulungiswa kwamandla kagesi nokwenyusa.

Kubalulekile ukuqaphela ukuthi lapho uxhuma amabhethri ochungechungeni noma ngokufana, wonke amabhethri kufanele abe ngohlobo olufanayo namandla, futhi kufanele akhokhiswe ngokugcwele ngaphambi kokuxhuma.
