WHAKAMĀRAMA

He momo matū, he pūrere rānei ka whakaiti i te iahiko i tētahi ara iahiko. Ka hurihia ētahi o te pūngao hiko, ka uru atu ki te parenga hiko hei pūngao kē atu, pērā i te pūngao pōkākā, i te aho rānei.

A material or device which limits the electrical current flowing in a circuit. Some of the electrical energy going into the resistor is changed into other forms of energy, such as heat or light.

Tauira KŌrero

Tohua ngā parenga iahiko i tēnei ara iahiko.

He aha i wera ai te parenga iahiko?

Tātaihia te parenga iahiko o te rama.

WhakamĀrama Āpitihanga

Ko te Ω hei tohu mō te wae parehiko.

Ka wehea te ngaohiko (V) o tētahi ara iahiko ki te iahiko (I) e rere ana hei tātai i te parenga iahiko o tētahi pūrere hiko (R). Arā te whārite:

Hei tauira, e 6 te wae ngaohiko (6V) o te pūhiko i tēnei ara iahiko, ko te 0.5 te wae iahiko (0.5A) e rere ana:

Nō reira, hei tātai i te parenga iahiko o te pūrama:
