PTCKo te tikanga "Poitive Temperature Coefficient" i roto i te whakamahana miihini.He nui te wera o te miihini o te motoka wahie ka tiimata ana.Ka whakamahia e nga miihini miihini te wera o te miihini ki te whakamahana i te motuka, te whakamahana hau, te whakakore i te hukapapa, te whakakore, te whakamahana nohoanga me etahi atu.Engari, i roto i te motuka hiko hou, ko te whakakapi mo te miihini ko te motuka hiko, he iti ake te wera o tana mahi i te miihini.Ko te whakakapinga o te penehīni ko te pākahiko, ko te kete pākahiko i roto i te pūtau pākahiko he tino tairongo ki te pāmahana, engari me hiahia hoki tetahi taiao pāmahana hei whakarite i tana rokiroki haumaru me te whai hua me te hurihanga.Ko te whakamahana, mai i te hurihanga hiko, te miihini mo te penehīni na roto i te wera ki te wera, te wera ki te hiko miihini, ko te motuka ko te huri tika o te hiko hiko ki te hiko miihini, mai i te tere o te hurihanga, ka pau te kaha o te miihini, tera waahanga o tino kore e taea te moumou te pūngao, i roto i te rangi makariri, ka taea e koe te whakamahana i roto i te pūnaha whāhauhau, i te mea e kore e ranea te wera o te motuka ki te whakamahana i te motuka katoa me te kete pākahiko.
Engari he iti te tinana o te tangata i te pāmahana e taea ai e ia te urutau, me pehea te mahi?
Tāpirihia he "whakarererangi mahana"PTC whakamahanaki te waka.
He rite ki te nuinga o nga taputapu whakamahana hiko, penei i te tunu raihi, te tunu tunu, te whakamahana hau, me era atu.Nga whakamahana PTCka whakamahia hoki ki te whakaputa i te wera nui ma te whakakaha i nga rauemi waiariki penei i nga waea whakaahuru / karaima hei whakarato i te wera e hiahiatia ana e te waka.Ki te kore e ranea tetahi, katahi ka taapirihia tetahi, ka whakanuia ano te mana.Ko te wera i hangaia Q=I²R*T, he pumau te ia, ka nui ake te uara parenga, ka nui ake te mana, ka nui ake te wera i puta mo ia wa wae;he u te naianei, he pumau te uara parenga, ka roa te wa, ka pau te kaha.
