He aha te rereketanga o te W me te Wh?

He rereketanga nui tenei, me maumahara ki te titiro ki nga korero o te teihana hiko kawe.

Ko W, Watts ranei te mana, oomph ranei ka taea e te teihana hiko kawe ki te taputapu taputapu ranei. Hei tauira, mena ka rere to whakamaroke makawe i te 1800W AC, ko te tikanga ka hiahia koe ki te tuku hiko ka taea te tuku i te 1800W (1.8kW) iti rawa o te waa tauutuutu (ara, penei i te tuku hiko hiko). I te nuinga o te waa, he mea utu ano kia nui ake te waahi o te upoko i runga ake i tenei uara - na reira ka tūtohu matou he putea pākahiko 2000W mo te keehi o runga ake nei.

Engari, ko te Wh he kupu poto mo Watt Hours. He waeine tino rerekee tenei, e tohu ana ki te nui o te rokiroki, te kaha ranei o te kete hiko puni - ara, kia pehea te roa o te kete hiko mai i te kaa ka whakakiia ki te watea i te wa e whakahaere ana tetahi taputapu. Hei tauira, mena he teihana hiko 30Wh te kaha o te tikanga ka taea e koe te whakahaere, te utu ranei i tetahi taputapu 30 watt (W) mo te 1 haora i mua i te paunga o te putea hiko.

Ka taea e nga kete hiko nui ake te kaha - hei tauira ko te iFlowPower's FP2000 he 2000Wh nui ka taea te tuku i te mana teitei o te 2000W mo te 1 haora. Ko te tikanga mena kei te whakahaere koe i te whakamaroke makawe 1800W ma te whakamahi tonu i tenei teihana hiko, ka mau tonu ~2000/1800 = 1.11 haora, 66 meneti ranei i mua i te noho kau. Kaore i te roa, engari katahi ano ka whakamahi koe i te whakamaroke makawe, i te ketere ranei i roto i te 2-3 meneti ka pakaru.
