DC ki te ora te tangata

He te wā "DC" e rave rahi momo o whakamāramatanga, me ia o ratou tika tokanga makehe. I roto i te nuinga o te wā, ka karanga i tenei ariā ko te nāianei hiko he tamau i runga i-wā āhuatanga, te aronga me ngā tautuhinga. Ko taea anake DC oraraa i roto i te ara iahiko kati. Ko tenei e tika ana ki te hiahia ki te mau tonu i te ngaohiko tamau, e te mea faufaa ki tenei āhuatanga. Ahakoa te momo puna DC, tonu tonu te taua te whakamāramatanga.

he maha o puna, kei te kaha i whakamahia i roto i te rā o nāianei Direct he ora. Ko te mea matua ko mō generators hiko. Ko te puna, he photocells hoki, pūtau galvanic me thermocouples. Ka taea te huaina te momo māmā o DC pūtake pākahiko (pūtau pūhiko). I roto i tenei take, kua te DC he āhuatanga motuhake - te taea o te whakamahi maha, hanga enei āhuatanga rawa whai hua, me te ngāwari i roto i te mahi o ia rā. Whakaae, ki te whiwhi wā katoa pākahiko tikanga mo te kāmera, ka whakanui i te utu o ngā pikitia nui. Hanga tenei tukanga taea e tika ana ki te taonga o te ànui o te tauhohe matū.

mihini Electrical me generators DC he electromechanical mana DC. Power DC Pūtake - tahuri aunoa mana ki nāianei hiko. Ko tā te reira i te momo o waka hiko, me te tahi atu waka. A i runga i te hanga i taua o te hiko tikanga kē e hāngai ana - te hau, me te huringa.

He maha ngā momo o pūtahuri DC. Ko te kē tino noa - te rectifier, tino noa te i whakamahia i roto i ngā pūrere mahi i te mains. Whakaröpütia Rectifiers i runga i te mana o te ara iahiko rectifier matua rānei, i runga i te maha o ngā wāhanga e kua whakamahia i roto i te mahi rānei. Hoki e whakamahia amplifiers tahi-DC ki a ratou. I tua atu, taatou he putanga whakahaere whakarōpū taea tawhā i te aroaro o ngā pūrere stabilization. rerekē katoa taea o te rārangi whakarōpūtanga he tata e taea. Ko, tetahi ara ranei tetahi, tata e hakari i roto i to tatou mau utuafare, me whaitua katoa o ratou, e rite ana kahore ratou he tata e taea ki te whakamahi i ngā taputapu hou.

Kei te tikanga o nāianei Direct whakamahia i roto i ngā taputapu. Ko te supply te mana o tata iahiko hiko katoa ko ïa te nāianei hiko. Hoki DC o makona aroaro o rua hiahiatanga - free utu hiko me te mara hiko.

I roto i te ao i teie mahana, e hua te nuinga hiko mana motuhake. tupu tenei anake i runga i te pūtake o whakaaro hangarau, me te ōhanga. tohaina mihi ki te mana o nāianei tika i roto i farii maha e pau mana kore te mea tamau, me te nāianei tauutuutu. Ko reira anake ka tae koe ki te ūnga motuhake, he nāianei tauutuutu tahuri te ki e whakatika o nāianei i roto i ngā pūrere ohie. Tētahi atu wāhi o te tono o DC i te ao hou - nga rerewē. He maha ngā tauira o te mahi hiko te nuinga e tika ana ki te kohi o nāianei hiko.

Ka rite ki taea e matou te titiro, kua whakarārangitia i runga ake o te katoa, ka taea e tatou e faaoti e te DC reliably tango te mata i roto i te tukanga o te ora tangata. He uaua ki te whakaaro nga mea e pa ki te tangata, ki te ka ngaro i te hiko me te pō o nāianei tonu!
