Whārite o te Ātete Hiko
I roto i te kaupapa o te ture a Ohm, kua ahu mai he tātai e whakaatu ana i te whanaungatanga i waenga i te ngaohiko (V), te iahiko hiko (I), me te ātete hiko (R). E whakaatuhia ana mā te pāngarau mā roto i ngā whārite:
E whakaatu ana tēnei whārite he rite tonu te ātete hiko (R) ki te ngaohiko hiko (V) me te rite whakamuri ki te iahiko hiko (I). Mena he nui ake te ngaohiko matua i te ātete hiko, ka nui haere, engari, ki te kaha ake te iahiko hiko, ka nui ake te ātete hiko. Ka whakamāramahia e tēnei whārite te ture a Ohm ina pumau te ātete hiko (R). Mena kāore te ātete hiko i te pumau, kāore tēnei whārite e whakamārama i te ture a Ohm, engari e whakamārama ana i te ātete o te kaiārahi hiko.
I roto i te tuhinga mō te ture a Ohm, kua whakamāramahia te whanaungatanga i waenga i te ātete o te arataki hiko (R), te ātete momo, te ātete arataki rānei (ρ), te roa o te arataki (l), me te horahanga whakawhiti arataki (A). Kua whakaaturia i roto i te whārite mā te pāngarau:
I runga i tēnei whārite, ka whakatauhia ko te ātete hiko he rite tonu ki te ātete o te momo me te roa o te kaiārahi, engari he rite whakamuri ki te horahanga whakawhiti o te kaiārahi. Arā, ka piki ake te ātete hiko ina piki ake te ātete o te momo me te roa o te kaiārahi, engari ka heke te ātete hiko mena ka piki ake te horahanga whakawhiti o te kaiārahi.
Mena he pumau te roa o te arataki (l) me te horahanga whakawhiti-wāhanga (A), ko te ātete hiko (R) ka whakawhirinaki anake ki te momo ātete (ρ). Mena ka piki te momo ātete, ka piki te ātete hiko, engari ki te whakaitihia te momo ātete, ka heke te ātete hiko. Ko te uara ātete o ia momo arataki he rite tonu ki te pāmahana,
Ki te nui haere te pāmahana i te momo ātete, ka nui haere rānei, ki te iti haere te pāmahana, ka iti haere te ātete o te momo.
Ko te momo ātete rerekē (ātete) ko te kawe hiko. He rite whakamuri te kawe hiko ki te ātete, e ai ki te whārite i raro nei:
Mena ka whakaaturia ki te kawe hiko, ka huri te whārite 2 ki:
I runga i tēnei whārite, ka taea te whakatau ko te ātete hiko he rite whakamuri ki te kawe hiko,
Mena he nui ake te kawe hiko o te kaiwhakahaere hiko i te, ka iti ake te ātete hiko, mena he iti ake te kawe hiko o te kaiwhakahaere hiko i te, ka nui ake te ātete hiko.
Kei te ripanga i raro nei te uara ātete o ia momo rauemi.
Te wae o te ātete
Ko te waeine hiko ko Volt, ko te waeine iahiko ko Ampere, nō reira ko te waeine ātete hiko ko Volt/Ampere. E kiia ana hoki ko te Volt/Ampere ko Ohm, e tohuhia ana e Ω, hei whakanui i a Georg Simon Ohm (1789-1854), he tohunga ahupūngao Tiamana. Haunga te Ohm, e whakamahia ana hoki ngā waeine kilo-ohm me megaohm. 1 kilo-ohm (kΩ) = 1000 Ω = 103 Ω , ko te 1 mega-ohm (MΩ) = 1000,000 Ω = 106 Ω.
Ngā taputapu ine ātete
Ko te taputapu ine mō te ātete hiko he ohmmeter. Kua whakauruhia tēnei taputapu ine ki roto i te multimeter, he taputapu hei ine i te ngaohiko hiko, te iahiko hiko, me te ātete hiko.
