I roto i tō tātou ao matihiko me te ao pūkoro e piki haere ana, kua rite te hiranga o te utu i ā tātou taputapu hiko ki te kai, ki te moe rānei. Ahakoa e mōhio ana te nuinga o te tangata ki ngā rihi AC (aukume whakawhiti) paerewa e mono ana ki ngā putanga pakitara, he rite tonu te hiranga o ngā rihi DC (aukume tika) ki te whakakaha i ā tātou taputapu hou. E whakamahia ana ngā rihi DC puta noa i te whānuitanga o ngā taputapu hiko, mai i ngā taputapu kawe iti ki ngā waka hiko nui. Ka tūhuratia e tēnei aratohu whānui ngā momo taputapu e whakawhirinaki ana ki te hiko DC, me pēhea te mahi a te utu DC, me te take i tino horapa ai i roto i tō tātou pūnaha hangarau.
Te Mārama ki ngā Taura DC
I mua i te ruku ki ngā taputapu e whakamahi ana i ēnei, he mea nui kia mārama ki ngā āhuatanga rerekē o ngā rihi hiko DC. Kāore i rite ki te AC (aukume hurihuri) e huri ana i te ahunga i ia wā, ka rere tonu te DC (aukume tika) i te kotahi ahunga. Ko te nuinga o ngā taputapu hiko e mahi ana i te hiko DC i roto, koia te take he mea noa ngā rihi hiko DC - ka whakaratohia te hiko i roto i te āhua ka taea e ngā taputapu te whakamahi pai rawa atu me te kore e hiahiatia he huringa ā-roto.
Ko ngā rihi hiko DC te tikanga ka huri i te hiko AC mai i ngā putanga pakitara ki te hiko DC i te ngaohiko motuhake e tika ana mō te taputapu ūnga. He maha ngā āhua o ēnei tae atu ki:
