electrical current (I)

WHAKAMĀRAMA

Ko te rere o te whana hiko. I te nuinga o te wā, ko te rere o te irahiko i tētahi pūkawe hiko hei kawe i te pūngao hiko, huri noa i tētahi ara iahiko. Ko te rahi o te iahiko, kei te āhua tonu o te parenga iahiko o ngā pūrere me nga waehanga i te ara iahiko, me te ngaohiko e puta ana i te puna hiko.

The flow of an electric charge. Usually this is the flow of electrons in an electrical conductor, and this carries electrical energy around a circuit. The size of the electrical current is dependent on the resistance of the devices and components in the circuit and the voltage of the electrical source.

Tauira KŌrero

Me pēhea te ine i te iahiko?

Mēnā he rahi te parenga hiko, he iti te iahiko.

Wehea te ngaohiko ki te parenga iahiko hei tātai i te iahiko.

Ka rere ngā irahiko mai i te pito tōraro o te pūhiko, huri amio i te ara iahiko ki te pito tōrunga o te pūhiko. He pēnei te rere o ngā irahiko nā te panapana o te pito tōraro i ngā irahiko:

 

Engari, nō mua kē atu i te mārama ki tēnei mea te irahiko, i tau te whakaaro o ngā mātanga pūtaiao kia whakaaturia te rere o te iahiko mai i te pito tōrunga ki te pito tōraro. Ahakoa te hē o tēnei tikanga, kei te mau tonu! Arā, koia nei te tikanga mō te whakaatu iahiko ki tētahi hoahoa:

 

He rahi ake te parenga iahiko mēnā e rua ngā pūrama i te ara iahiko. Nō reira, he iti ake te iahiko e rere ana. Nā tēnei, kāore i te pērā rawa te kanapa o ngā pūrama:

 

E rua ngā momo iahiko:

  • Ko te iahiko hohoko (AC):
    Ka hohoko haere te ahunga o te iahiko i te ara iahiko. Koirā te āhua o te hiko ka puta i ngā punahiko o te motu, ā, ka kawea ake ki ō tātou whare, ki reira whakakā ai i ngā pūrama me ngā pūrere hiko. Ko te painga o te iahiko hohoko, ka taea te whakapiki ake, te whakaheke iho rānei i te ngaohiko (V) mā te whitihiko. Ka whakapikihia ake ki te 10,000V, e pai ai te kawenga mā roto i ngā waea mātotoru ki tēnā wāhi, ki tēnā wāhi o te motu. Ka whakahekea iho ki te 240V i mua i te kawenga ake ki roto i ō tātou kāinga.
