Tirohanga
Ko te tohu puoro wiri he whakauru ki roto i te arai haumaru motuhake, ka taea te mohio ki te 1: 1 te tuku taratahi o te whakaputanga tohu ngaohiko kino e te puoro wiri i roto i te waahi kino ki te waahi haumaru, ka taea te tuku tohu AC me te DC, he mahi anti-porearea teitei. Ko te ara iahiko he tuku hiko motuhake mo nga taputapu mara.
Ko tenei hua e hiahia ana ki te tuku hiko motuhake, a ka wehea te hiko, te whakauru me te whakaputa.
