Dahaarka biraha ah ee biraha uma baahna diyaargarow badan maadaama biraha ay yihiin kaari wanaagsan.Alaabta korontadu liidato, dusha sare waxay u baahan tahay in marka hore la diyaariyo.Tan waxaa lagu samayn karaa iyada oo loo marayo dahaarka elektaroonigga ah ama hababka kale ee diyaarinta kiimikada.
Dahaarka macdanku wuxuu siinayaa dhalaal macdan ah iyo dhammayn dhalaal leh oog kasta oo lagu mariyo.Dhammaystirka sidoo kale waa daxalka, iftiinka qoraxda iyo oksaydhka u adkaysta.
