Umzobo kwisilawuli sombane wethu uyatshintsha kuba ubonisa amandla ombane wokwenyani.Ngokubanzi, i-voltage regulator inokuzinzisa i-voltage, kodwa kunzima phantse kuzo zonke izilawuli zombane zesigaba esinye ukugcina umbane uzinzile kwinqanaba elifanayo lonke ixesha.Kufuneka kubekho ilahleko yamandla ngexesha lenkqubo yonke.Okufana nokufudumeza okubangela ukulahleka kwamandla.Nangona i-voltage elawula abanye abavelisi iya kuhlala ingatshintshi, baye bamisela iinkqubo ezithile ukugcina inani lingatshintshi.
