Haka kuma, goga B koyaushe yana da polarity mara kyau, don haka ƙarshen goga na iya haifar da ƙarfin bugun zuciya na lantarki mai alkibla akai-akai amma girma daban-daban. Idan an ƙara yawan na'urori a ƙarƙashin kowane sanda, za a iya rage matakin girgizar bugun jini kuma za a iya samun ƙarfin lantarki na dc.
Haka injinan dc ke aiki. Hakanan yana nuna cewa injin sub-dc a zahiri janareta ne na AC tare da commutator.
Dangane da gabatarwar masana'antun injinan girgiza, daga yanayin lantarki na asali, injin dc a ƙa'ida yana iya aiki azaman injin da ke aiki, ana iya kuma gudanar da shi azaman janareta, amma iyakokin sun bambanta.
