• Cibiyoyin bayanai suna karɓar rarraba wutar lantarki ta 380V DC
• Tsarin ci gaban DC na iya yiwuwa a cikin gida

Kammalawa: Duniyar DC da ta mamaye duniya

Duk da cewa AC ta yi nasara a yaƙin watsa wutar lantarki, DC ta yi nasara a yaƙin sarrafa na'urori. Daga wayar salula da ke aljihunka zuwa na'urorin hasken rana da ke kan rufinka, wutar lantarki kai tsaye tana ba da ƙarfi ga mafi mahimmancin fasaharmu. Fahimtar waɗanne na'urori ne ke buƙatar DC yana taimakawa da:

• Zaɓin kayan aiki masu kyau
• Zaɓuɓɓukan samar da wutar lantarki mai aminci
• Tsarin makamashin gida na gaba
• Gyaran matsala ta fasaha

Yayin da muke ci gaba zuwa ga ƙarin makamashi mai sabuntawa da samar da wutar lantarki, muhimmancin DC zai ƙaru ne kawai. Na'urorin da aka nuna a nan suna wakiltar farkon makoma mai amfani da DC wanda ke alƙawarin ingantaccen aiki da tsarin makamashi mai sauƙi.
