E mōhio ana pea te katoa ki ngā mita hiko. I ēnei rā, he maha ngā wā ka whakamahia ngā mita atamai hei ine me te utu i ngā hiko o te whare. Ki te titiro pai koe, ka kitea e koe he tawhā 5 (60) kua tuhia ki te tūranga kitea o te mita hiko.

Hei tauira, ko te tawhā i roto i te porowhita whero i te pikitia i runga ake nei: 5 (60) A. Ina tirohia te waeine, e mōhio ana tātou kua tuhia hei iahiko, nō reira he aha te whanaungatanga i waenganui i ēnei iahiko e rua? He aha te mea ka puta ina hipa te iahiko? Me kōrero tātou mō ngā mea e pā ana ki ngā iahiko e rua e ai ki ngā pūtu o waho (5) me roto i ngā pūtu (60).
Au i roto i ngā taiapa
Ko te iahiko i roto i ngā pareneti – 60A i roto i te tauira, e pā ana ki te iahiko whakatauranga mōrahi o te mita pūngao. He rerekē i ētahi atu taputapu, he nui te pānga o te taiao ki te iahiko whakatauranga o te mita pūngao hiko, nō reira he whānui te toenga ina puta mai i te wheketere – ko te iahiko whakatauranga mōrahi tuturu ko te 120% o te iahiko kua tohua. Nō reira, ki te mea ko te tau i roto i ngā pareneti he 60, ko tōna iahiko whakatauranga mōrahi ko te 72A – ki te kore e tino kino te taiao, ko te pānga ki te iahiko whakatauranga mōrahi e kore e eke ki te 20%. Nō reira, ko te iahiko whakatauranga mōrahi o te mita kua tohua ki te 60A he tata ki te 66A i te whakamahinga tuturu.
Ka aha mēnā ka hipa atu i tēnei uara? Ko te whakautu he ine hē – he nui ake pea, he iti iho pea.
Ngā taiapa o waho o nāianei
Ko te 5 i waho o ngā pareneti i konei e kiia ana ko te iahiko taketake, e kiia ana hoki ko te iahiko whakatikatika. Ka whakatauhia e te iahiko tīmatanga o te mita hiko – te uara iahiko iti rawa e taea ai e te mita hiko te hurihuri tonu me te ine tonu. Ko te iahiko tīmatanga o te mita atamai whānui he 0.4% o te iahiko whakatauranga. Arā, ka utua he mita me te iahiko whakatauranga o te 5A i te mea ka eke te iahiko i roto i te ara iahiko ki te 0.02A i te wā e whakamahia ana. Ka puta he ōwehenga i waenga i te iahiko whakatauranga me te iahiko whakatauranga mōrahi, pērā i te 5 (60) A, he whanaungatanga 4 ngā wā. Ka kiia tēnei ōwehenga ko te "whānui kawenga". I te nuinga o te wā, e 2 ngā wā, 4 ngā wā, 6 ngā wā, 8 ngā wā, neke atu rānei i te tekau ngā wā – ko te nui ake o te whānui kawenga, ko te kaha ake o te taumata hangarau e hiahiatia ana, ā, ko te utu mō te mita ka teitei ake.
Nō reira, kāore he pānga o ngā tau kei waho o ngā pareneti ki te whakamahinga tuturu a te kaiwhakamahi—kāore he pānga o te nui ake, te iti iho rānei i tēnei uara ki te inenga o te mita. E rua ngā āhuatanga matua e pāngia ana e te ia o te whakataurite: te utu o te mita (e pā ana ki te whānui o te kawenga) me te ia tīmatanga (e tatauhia ana e te ia o te whakataurite).
