Abanye abantu babuza ukuthi ikhebula lokushisisa elizibekela umkhawulo kuyikhebuli yokushisisa ehambisanayo, i-voltage yesigaba sokuqala nesokugcina kufanele ilingane, futhi izinga lokushisa lesigaba ngasinye kufanele lilingane. Kungaba kanjani ukushisa okuphansi kokushisisa ekugcineni? Lokhu kufanele kuhlaziywe kusukela kumgomo womehluko we-voltage kanye nesimiso sokushisa okuzibekela umkhawulo.

Uyini umehluko we-voltage? Lapho i-current idlula ikhebula lokushisa likagesi, kuzoba nomehluko we-voltage phakathi kweziphetho zayo ezimbili. Umsebenzi we-voltage ukusiza amandla amanje ukuthi adlule ekuphikiseni kahle futhi enze iluphu. Uma kukhulu ukumelana, kuba mkhulu ushintsho kumahluko kagesi.

Ikhebula lokushisa elizibekela umkhawulo wezinga lokushisa ngokwalo linezici zokushintsha ngokushintsha kwezinga lokushisa le-ambient. Ukushisa okuphezulu kwe-ambient kuzokwandisa ukumelana futhi kunciphise okwamanje okudlulayo. Izinga lokushisa ekugcineni komsila liphansi, okungase kube ngenxa yokuthi ukumelana kuba kukhudlwana, umzuzwana odlulayo uba mncane, futhi umehluko we-voltage phakathi kokuphela kwekhanda nomsila uba mkhulu, okuyinto evamile.

Esinye isizathu ukuthi ubude bekhebula lokushisa lokushisa elizibekela umkhawulo ngokwalo buyadlula phakathi nenqubo yokufaka. Ngenxa yokuthi ukushisa okuzibekela umkhawulo wokushisa kagesi ukumelana kuzoshintsha ngokushisa, ukuphakama kokumelana ekupheleni kwekhebula lokushisa, kunciphisa izinga lokushisa. Ukuze ugweme lesi simo, ubude obuthile bekhebula lokushisa likagesi kufanele bugcinwe ngesikhathi sokufakwa.
