1. Direction: In direct current, alkiblar halin yanzu tana kasancewa iri daya ne, tana gudana ta hanya daya. Sabanin haka, alkiblar halin yanzu a cikin canjin halin yanzu yana canzawa lokaci-lokaci, yana musanya tsakanin ingantattun kwatance da mara kyau.
2. Canjin wutar lantarki: Wutar lantarki na DC ya kasance koyaushe kuma baya canzawa akan lokaci. Wutar wutar lantarki ta alternating current (AC), a daya bangaren, tana cikin sinusoidal akan lokaci, kuma mitar yawanci 50 Hz ko 60 Hz ne.
3. Nisan watsawa: DC yana da ƙarancin ƙarancin kuzari yayin watsawa kuma ana iya watsa shi ta nisa mai nisa. Yayin da ikon AC a cikin watsawar nesa mai nisa zai sami babban asarar makamashi, don haka buƙatar daidaitawa da ramawa ta hanyar transfoma.
4. Nau'in samar da wutar lantarki: Kayan wutar lantarki na yau da kullun na DC sun haɗa da batura da ƙwayoyin rana, da sauransu. Yayin da wutar lantarki galibi ana samar da wutar lantarki ta AC kuma ana samar da ita ta hanyar transfoma da layin watsa don amfanin gida da masana'antu.
5. Yankunan aikace-aikacen: Ana amfani da DC a cikin kayan lantarki, motocin lantarki,Tashoshin Cajin EV, da dai sauransu AC ana amfani dashi sosai a aikace-aikacen gida. Alternating current (AC) ana amfani dashi sosai a cikin wutar lantarki na gida, samar da masana'antu, da watsa wutar lantarki.
6. Ƙarfin halin yanzu: Ƙarfin AC na yanzu zai iya bambanta a cikin hawan keke, yayin da na DC yakan kasance akai-akai. Wannan yana nufin cewa don irin ƙarfin, ƙarfin AC na yanzu yana iya zama mafi girma fiye da na DC.
7. Tasiri da aminci: Saboda bambance-bambance a cikin shugabanci na yanzu da ƙarfin lantarki na halin yanzu, yana iya haifar da radiation na lantarki, inductive da capacitive effects. Waɗannan illolin na iya yin tasiri akan aikin kayan aiki da lafiyar ɗan adam a ƙarƙashin wasu yanayi.

8. Hasarawar Watsawa: Ƙarfin DC yana da ƙarancin asarar makamashi lokacin da ake watsa shi a cikin nesa mai nisa saboda juriya da inductance na ikon AC ba ya shafar shi. Wannan ya sa DC ta fi dacewa wajen watsa nisa mai nisa da canja wurin wuta.
9. Farashin kayan aiki: Kayan aikin AC (misali, taransfoma, janareta, da sauransu) sun fi kowa yawa kuma balagagge, don haka farashin sa ba shi da yawa. Kayan aiki na DC (misali,inverters, masu sarrafa wutar lantarki, da sauransu), a gefe guda, yawanci sun fi tsada. Koyaya, tare da haɓaka fasahar DC, farashin kayan aikin DC yana raguwa a hankali.
