Electric wires are used to conduct electric current around the motor vehicle. The wire is commonly braided multi-stranded copper core wrapped with plastic insulation. Copper is used as it offers low resistance and remains flexible even after years of use. Other wire configurations are shielded wires and ribbon.
Twisted or shielded wires have the same construction but are harnessed in pairs and twisted to cancel the effect of electromagnetic interference.
Ribbon cable is found inside computers and other electronic components. It is used for connecting between printed circuits.
