I roto i tō tātou ao matihiko e piki haere ana, kua tino hira te pupuri i ā tātou taputapu hiko DC (auau tika). Engari he aha te mea ka puta ina kore he rihi tika? Ahakoa kua ngaro tō rihi, kua pakaru rānei, kāore rānei he rihi e wātea ana, he maha ngā huarahi kē atu hei whakakaha i ō taputapu DC. Ka tūhuratia e tēnei aratohu whānui ngā otinga auaha hei whakakaha i ō taputapu hiko DC me te kore he rihi taketake.
Te Mārama ki ngā Kaupapa Taketake o te Mana DC
I mua i te tūhuratanga i ngā tikanga utu rerekē, he mea nui kia mārama ki ētahi o ngā kaupapa matua mō te mana DC:
- DC me ACKo te nuinga o ngā taputapu hiko e whakamahi ana i te hiko DC, ko ngā putanga pakitara ia e whakarato ana i te hiko AC (aukume whakawhiti). Ka hurihia e ngā rihi hiko te hiko AC ki te hiko DC i te ngaohiko tika.
- Ngā whakaritenga hikoHe motuhake ngā hiahia hiko o ia taputapu (hei tauira, 5V mō te USB, 12V mō te nuinga o ngā hikohiko).
- Ngā whakaritenga o nāianeiMe tutuki, me neke atu rānei te amperage (iahiko) i ngā hiahia o te taputapu.
- Te āhua o te polarityHe hononga hiko DC kei ngā pito pai me ngā pito kino, ā, me ōrite tika ēnei.
