He aha i whakamahia ai e ētahi ara iahiko ngā ātete taurangi?
- WhakautuMā ngā ātete taurangi, pērā i ngā potentiometer, ngā rheostat rānei, ka taea te whakarerekē i te ātete i roto i te ara iahiko. He mea whai hua tēnei mō te whakatikatika, te whakarerekē rānei i ngā tawhā ara iahiko, pērā i te oro i roto i ngā taputapu oro, te kanapa rānei o te mārama.
He aha te mea ka tupu mēnā ka rahua (ka tuwhera) tētahi ātete i roto i tētahi ara iahiko raupapa?
- WhakautuKi te kore e rahua tētahi ātete i roto i tētahi ara iahiko raupapa mā te huri hei ara iahiko tuwhera, ka tuwhera katoa te ara iahiko, ā, kāore he iahiko e rere mā roto. He rite ki te pakaru o tētahi paipa wai.
He aha te mea ka tupu mēnā ka rahua (ka tuwhera) tētahi ātete i roto i tētahi ara iahiko whakarara?
- WhakautuKi te kore e angitu tētahi ātete i roto i tētahi ara iahiko whakarara mā te huri hei ara iahiko tuwhera, ka mau tonu te iahiko i ngā manga whakarara e toe ana. Ka piki ake te ātete katoa o te ara iahiko mai i te mea kua tangohia tētahi o ngā ara whakarara.
He aha i whakamahia ai e ētahi ara iahiko ngā ātete he tino teitei ngā uara ātete, i ētahi wā i roto i te raupapa o ngā megaohms?
- WhakautuKa taea te whakamahi i ngā uara ātete teitei mō ngā kaupapa maha, pērā i te hanga wehewehe ngaohiko, te whakahāngai i ngā transistors, te mahi rānei me ngā tono iahiko tino iti. Ka taea e rātou te whakarite kia iti rawa te rere o te iahiko i roto i ētahi wāhanga o ngā ara iahiko, inā koa ka hiahiatia he aro, he tika rānei.
He pēhea te pānga o te pāmahana ki te ātete o te nuinga o ngā ātete?
- WhakautuMō te nuinga o ngā rauemi, ka piki ake te ātete i te pāmahana. Ko te nui o te huringa ātete i te pāmahana ka whakatauhia e te tauwehenga ātete pāmahana o te rauemi. Ko ētahi ātete he mea hanga motuhake kia iti noa te huringa o te ātete i te pāmahana (e kiia ana ēnei he ātete pumau-mahana, he ātete pāmahana-iti rānei).
He aha i whakamahia ai ngā ātete kukume-ake me ngā ātete kukume-iho i roto i ngā ara iahiko mamati?

WhakautuKa whakamahia ngā ātete kukume-ake me ngā ātete kukume-iho hei tautuhi i te āhua taunoa (kore mahi) o te pine tāuru mamati. Ka hono te ātete kukume-ake i te pine tāuru ki te ngaohiko pai ina kore he tohu hohe e whakamahia ana, kia mau ai te āhua TEITEI taunoa. I tetahi atu taha, ka hono te ātete kukume-iho i te pine tāuru ki te whenua, kia mau ai te āhua ITI taunoa.
