fasaha sigogi:
• Shigar da ƙarfin lantarki = fitarwa ƙarfin lantarki = abokin ciniki gida rated ƙarfin lantarki (don Allah sanar da takamaiman darajar shigar da ƙarfin lantarki a lokacin yin oda)
• Single mataki fitarwa halin yanzu = ikon * 80% / fitarwa ƙarfin lantarki
• Uku mataki fitarwa yanzu = ikon * 80% / 1.732 / fitarwa ƙarfin lantarki
• Output ikon = ainihin amfani da ikon * 1.5
