Ngoko ke, qiniseka ukuba udibanisa i-diode ngokuchanekileyo ngokuhambelana ne-polarity yayo, ukhangele i-database yayo ukuba kuyimfuneko.

Isishwankathelo, ukukhanyisa i-bulb ye-12 V kunye ne-transistor yisisombululo esisebenzayo kunye nezoqoqosho. Ngokulandela ezi ngcebiso, uya kuba nakho ukuqinisekisa ukutsha okuyimpumelelo, ukukhusela amacandelo abandakanyekayo, kwaye ufumane ukusebenza okuthembekileyo. ikhuselekile kwaye ithembekile kwiprojekthi yakho.⁤ Soloko ukhumbula ukubonisana nemigaqo yobugcisa yamacandelo kwaye ube nolwazi oluyimfuneko ekuphunyezweni kwawo okuchanekileyo.
