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.
pare - turn aside, ward off, divert
iahiko - electric current
