Ka pāngia te kaha tohatoha o ngā takai whakawhiti hiko e ngā momo tikanga waea rerekē, ka pā tika ki te mahi a ngā whakawhiti hiko. I roto i tēnei tuhinga, ka arotahi tātou ki te tawhā o ngā whakawhiti hiko.
Ko te kaha tohatoha o te whakawhiti hiko he kaha pirinoa i hangaia nā te noho mai o ngā rerekētanga pūmanawa. He tawhā hiko whānui tēnei, kei reira te kaha tohatoha i waenga i ngā ārai e rua mena he rerekētanga ngaohiko. He iti noa te pānga o te kaha tohatoha ki ngā ara iahiko i ngā auau iti, engari me whai whakaaro ki ōna pānga i ngā auau teitei.
Ka taea te wehewehe i te kaha tohatoha o ngā takai whakawhiti ki ngā wāhanga matua e whā:
(1) te kaha i waenga i ngā hurihanga. He kaha i hangaia e te rerekētanga pūmanawa i waenga i ngā hurihanga tata. Ahakoa he iti te uara kaha i waenga i ngā hurihanga takitahi, mā te utu me te tukunga i waenga i ngā hurihanga ka arahi pea ki te hekenga o te whakamarumaru, tae atu ki te pakaru me te ara iahiko poto o te waea enamel i roto i ngā āhuatanga ngaohiko teitei, mana teitei rānei.
(2) Te kaha ā-paparanga. Ko te kaha ā-paparanga i waenga i ngā paparanga rerekē i roto i te takai kotahi. Ko te kaha ā-paparanga te pūtake matua o te kaha ā-paparanga tohatoha, e hanga ana i tētahi porowhita wiri me te aukati turuturu i ngā auau teitei, e whakanui ana i ngā raruraru pokanoa hikohiko me te whakanui ake i te ahotea ngaohiko i runga i te transistor whakawhiti.
3) Te kaha honohono. Ko te kaha i waenga i te tuatahi me te tuarua, te tuatahi me te VCC, me te tuarua me te VCC. Ka whakaratohia e tēnei kaha he ara honohono mō te pokanoa aratau noa, ka taea ai te tuku haruru mai i te taha tuatahi ki te taha tuarua, ka pā ki te pumau o te putanga.
(4) Te kaha hiko hē. Ko te kaha hiko o ngā takai ki ngā matua aukume, ngā paparanga ārai, ngā anga rānei, ka puta mai i ngā āhuatanga pēnei i te ara iahiko, te hanganga, te tahora rānei. Ahakoa he iti ēnei kaha hiko, tera pea ka pā ki ngā āhuatanga auau-tiketike i raro i ngā tahora motuhake.
He kino te kaha tohatoha o ngā takai whakawhiti, ā, ko tōna pānga ki ngā ara iahiko penei:
1. Ngā take hototahi hikohiko. Mā te kaha tohatoha ka whakaratohia he ara hononga i waenga i ngā takai tuatahi me te tuarua, ka puta te haruru i te taha tuatahi ki te taha tuarua mā te kaha, ka hanga he pokanoa aratau noa, ka kino hoki te pono o te tohu o te ara iahiko.
2. Te hekenga o te whai huatanga. Ka taea e ngā pūnga tohatoha i roto i ngā ara iahiko te hanga i ngā iahiko pūnga, ka hua ake te pikinga o te mana tauhohe o ngā whakawhiti hiko me te hekenga o te whai huatanga whānui. Tuarua, ko te tukanga utu me te tukunga o te pūnga tohatoha ka whakanui ake i ngā mate tāpiri, ka piki ake te whakamahana o te takai, ā, ka heke te whai huatanga.
3. Te kino o te ārai. Ka taea e te kaha tohatoha te whakararu i te kukū o te mara hiko ā-rohe i roto i ngā āhuatanga ngaohiko teitei, ka piki ake te ia turuturu me te pakaru o ngā rauemi ārai.
4. Te hekenga o te pumau o te mahi. Ka hangaia e te kaha tohatoha me te aukati turuturu he ara iahiko whakakorikori, ka puta te wiri ngaohiko i roto i te pūtake hiko whakawhiti, ka hua ake he ahotea ngaohiko nui ki runga i te transistor whakawhiti me te kino ki te taputapu.
I roto i ngā tono auau-tiketike, ka taea e te kaha tohatoha te whakarerekē i te tauira ara iahiko ōrite o ngā whakawhiti hiko, ka puta ai te urupare auau ki te uara hoahoa, ā, ka pā ki te pumau o te ara iahiko. Ka taea hoki e te kaha tohatoha te tuku haruru pana ki te pito putanga mā te hononga, ka whakanui ake i te riipene mana me te whakaiti i te kounga putanga.
5. Ngā herenga hoahoa me ngā utu kua piki ake. Hei pehi i te awe o te kaha tohatoha, me hoahoa pea ētahi atu ara iahiko whakaea RC, ka whakanui ake i te uaua me te utu o te hoahoa ara iahiko. I roto i ngā horopaki auau-tiketike, hei whakaiti i te kaha tohatoha, me whakamahi pea i ngā rauemi whakamahana utu nui ake me ngā tukanga uaua ki te hoahoa i ngā whakawhiti hiko, ā, ka piki ake ngā utu.
I roto i ngā whakawhiti hiko auau-tiketike, ka taea e tātou te whakaiti i te kaha tohatoha o te whakawhiti hiko mā te whakanui ake i te tawhiti i waenga i ngā takai, te whakanui ake i te matotoru o te whakamarumaru, te whakamahi i ngā rauemi whakamarumaru pumau iti-hiko, te whakapai ake i ngā tikanga takai, me te whakanui ake i te hoahoa paparanga whakamarumaru.
